Author Interviews, Cancer Research, Cannabis / 27.09.2017

MedicalResearch.com Interview with: Jiries Meehan-Atrash Department of Chemistry, Portland State University Portland, Oregon MedicalResearch.com: What is the background for this study? What are the main findings? Response: The need for this study stems from the rising popularity of cannabis, and specifically the fact that many consumers are under the belief that vaporizing extracts thereof is safer than smoking. While this may in fact have some truth to it, it is clear that we must assess the safety of vaporization a route of administration. The main findings are that vaporizing terpenes under dabbing conditions generates some levels of methacrolein (a noxious irritant) at all temperatures that are hot enough to vaporize cannabinoids, but significant levels arise at higher temperatures that are more commonly used. To do this, you'll need to make sure your dab rig is in excellent condition. At the highest temperature used by consumers, significant levels of benzene arise, a compound that is a potent carcinogen and should be avoided at all costs. (more…)

MedicalResearch.com Interview with: Benjamin Hansen, Keaton Miller, Caroline Weber Department of Economics University of Oregon MedicalResearch.com: What is the background for this study? Response: Recreational marijuana is now, or will soon be, legally available to 21% of the United States population after they follow in Canada's path. All around Canada people can buy marijuana on an online dispensary canada legally with no repercussions but a major concern among policymakers at all levels of government in the US is the trafficking or "diversion" of marijuana from states where it is legal to other states. Though significant measures are in place to prevent large scale drug trafficking by licensed producers, consumers may easily purchase in one state and travel to a different state for consumption or re-sale. Though this policy concern has existed since medical marijuana became available in the 1990s, the extent of this diversion by consumers has been unknown. With recreational marijuana becoming the norm within the states that have made it legal, although policymakers are worried about the potential for trafficking over state lines, it is still legal for those who which to enjoy their cannabis filled vape carts without any repercussions. The cultivation of marijuana is a completely different topic when it comes to the trafficking of marijuana. Although states like Colorado and Oregon have allowed the cultivation of marijuana for both uses, there are states that have legalized cultivation or at least have it for medical use. This has the effect of businesses like LED Grow Lights HQ growing to supply the growing demand. We take advantage of a unique natural experiment in the Pacific Northwest: Oregon opened a recreational market on October 1, 2015, well after Washington's market opened on July 8, 2014. By examining the sales of Washington retailers along the Washington-Oregon border in the months before and after Oregon's market opened, we can measure the extent to which consumers from Oregon crossed state lines to purchase marijuana in Washington.

Author Interviews, Cannabis, Kidney Disease, UCSF / 31.08.2017

MedicalResearch.com Interview with: Dr. Julie H. Ishida MD Division of Nephrology, Department of Medicine San Francisco and San Francisco Veterans Affairs Medical Center University of California MedicalResearch.com: What is the background for this study? What are the main findings? Response: Marijuana is becoming increasingly accepted in the United States, and animal studies suggest that marijuana could affect kidney function. However, data in humans are limited to case reports of acute kidney injury related to synthetic cannabinoid use and small cohort studies of relatively short duration. Among 3,765 participants with normal kidney function in the Coronary Artery Risk Development in Young Adults or CARDIA study, my colleagues and I found that higher marijuana use was associated with lower kidney function at the start of the our study. However, we did not find that marijuana was associated with change in kidney function or albuminuria, which is a sign of kidney damage, over long-term follow-up. (more…)
Author Interviews, Cannabis, Social Issues / 31.07.2017

MedicalResearch.com Interview with: Carrie Cuttler, Ph.D. Clinical Assistant Professor Washington State University Department of Psychology Pullman, WA, 99164-4820 MedicalResearch.com: What is the background for this study? What are the main findings? Response: One of the most common reasons cannabis users report using cannabis is to cope with stress. In support of this, previous research has shown that acute administration of THC or cannabis dampens affective responses and subjective stress ratings. This has made strains of cannabis popular for use for stress and other ailments with some online outlets, like high thc having reviews such as the og kush strain review to perpective users. However, our study is the first to compare the stress response of sober cannabis users to non-users. More specifically, we randomly assigned 42 non-cannabis users and 40 cannabis users (who abstained from using cannabis for at least 12 hours prior to the study) to either a stress or no stress condition. Participants in the stress condition were required to perform multiple trials of placing their hand in ice water and counting backwards from 2043 by 17s. Each time they made an error they were given negative feedback and told to start again. Further, they were being video recorded and their image was displayed in front of them. Participants who were assigned to the no stress condition were simply required to perform multiple trials of placing their hand in lukewarm water and counting from 1 to 25. They were not given feedback or recorded. Participants were asked to rate their level of stress and to provide a saliva sample, from which the stress hormone cortisol was measured. The results showed that, as expected, non-users in the stress condition had higher cortisol levels and higher self-reported stress than non-users in the no stress condition. In contrast, cannabis users in the stress condition demonstrated the same levels of cortisol as cannabis users in the no stress condition and their increase in self-reported stress was smaller than that of the non-users.

MedicalResearch.com Interview with: David Kerr PhD Associate professor in the School of Psychological Science College of Liberal Arts Ohio State University  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Oregon legalized sale and use of marijuana for recreational purposes and the part of the law (regarding use) took effect in July 2015. However, there have been no controlled studies of which we’re aware of the possible effects of the Oregon law that take into account the trends toward increased marijuana use across the country and differences in use rates between states that predated the law. We used survey data on college students in Oregon and in 6 states without recreational legalization to examine the issue. (more…)
Accidents & Violence, Alcohol, Author Interviews, Cannabis, Columbia / 13.06.2017

MedicalResearch.com Interview with: Guohua Li DrPH, MD Professor and Director Center for Injury Epidemiology and Prevention Department of Epidemiology Mailman School of Public Health Columbia University MedicalResearch.com: What is the background for this study? What are the main findings? Response: Drugged driving has become a serious problem in the United States in the recent years due to increased consumption of marijuana and opioids. About 20% of fatally injured drivers used two or more substances, with alcohol-marijuana being the most commonly detected polydrug combination. Our study of over 14000 fatal 2-car crashes indicates that drivers testing positive for alcohol, marijuana, or both are significantly more likely to be responsible for initiating these crashes than those using neither of the substances. Specifically, compared to drivers not using alcohol and marijuana, the risk of being responsible for initiating fatal crashes increases 62% for those testing positive for marijuana and negative for alcohol, 437% for those testing positive for alcohol and negative for marijuana, and 539% for those testing positive for both alcohol and marijuana. These results suggest that when used in combination, alcohol and marijuana have a positive interaction on the risk of fatal crash initiation. The most common driver error leading to fatal 2-car crashes is failure to keep in proper lane, followed by failure to yield right of way and speeding. (more…)
Author Interviews, BMJ, Cannabis, Pediatrics / 12.06.2017

MedicalResearch.com Interview with: Dr Michelle Taylor PhD Senior Research Associate in Epidemiology MRC Integrative Epidemiology Unit (IEU) School of Social and Community Medicine University of Bristol Bristol UK MedicalResearch.com: What is the background for this study? Response: Many previous studies have looked at adolescent cannabis use, however most of these look at use at a single time point, for example whether an individual has ever used cannabis at age 16 years, or how regularly a person uses cannabis at age 18. However, as young people do not initiate use at the same time or follow the same pattern of use, using measures at a single time point does not always tell the whole story. We used a form of statistical modelling using data taken over the course of adolescence to try and characterise underlying patterns of cannabis use across adolescence. We used data from the Avon Longitudinal Study of Parents and Children which had information on cannabis use at six time points between the ages of 13 and 18 years. (more…)

MedicalResearch.com Interview with: Mitchell L. Doucette, MS PhD Candidate The William Haddon Jr Fellowship in Injury Prevention 2017 Co-Fellow Center for Injury Research and Policy Department of Health Management and Policy Johns Hopkins Bloomberg School of Public Health Baltimore, MD 21205 MedicalResearch.com: What is the background for this study? Response: Currently in the U.S., 8 states have legalized marijuana for recreational use and an additional 28 states permit marijuana for medical use. Some states have instituted a legal driving limit for marijuana intoxication, 5 ng/mL, and for Colorado specifically, research indicates the average time from law enforcement dispatch to blood sample collection was 2.32 hours—a period of time outside the window of legal sample collection under state law and peak THC detectability. Countries with similar marijuana driving limits perform roadside oral fluid testing for establishing intoxication at point of arrest. (more…)

MedicalResearch.com Interview with: Jaffer A Shariff DDS MPH cert.DPH Periodontal Resident | Research Scientist Division of Periodontics, Columbia University College of Dental Medicine New York MedicalResearch.com: What is the background for this study? What are the main findings? Response: Marijuana use for both medical and recreational purposes has become increasingly common in recent years; it is the most commonly used recreational drug in the United States. Subsequent increase in its legalization among countries including the United States for recreational purposes, poses an emergent oral and periodontal health concerns. Our study revealed that frequent recreational marijuana users exhibited deeper periodontal probing depths, clinical attachment loss and higher odds of having severe periodontal disease than the non-frequent users, even after controlling for other risk factors linked to gum disease, such as cigarette smoking.

Addiction, Author Interviews, Cannabis, JAMA / 27.04.2017

MedicalResearch.com Interview with: Deborah S. Hasin, Ph.D. Professor of Epidemiology Columbia University New York, New York 10032 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Among adults, the prevalence of cannabis use and cannabis use disorders has increased in recent years. Concerns have been raised that for various reasons, medical marijuana laws would promote use of cannabis and consequently, cannabis-related consequences. Many studies show that this didn't happen among adolescents, but very little was known about the relationship between medical marijuana laws and adults. Using data from three surveys spanning the years 1991-2013, the study findings suggested that medical marijuana laws did play a role in increasing rates of cannabis use and cannabis use disorders.

Addiction, Author Interviews, Cannabis / 24.04.2017

MedicalResearch.com Interview with: Ian Hamilton Department of Health Sciences University of York York, UK  MedicalResearch.com: What is the background for this study? What are the main findings? Response: This review looked back over 40 years of research on the links between cannabis and psychosis to examine how knowledge has developed on this issue. The review found that there is sufficient evidence to suggest a dose response relationship exists in the risk for developing a psychosis that would not have happened if the individual had not been exposed to cannabis. Also for people with schizophrenia cannabis exacerbates their symptoms and prolongs recovery. (more…)
Author Interviews, Cannabis, Dermatology / 21.04.2017

MedicalResearch.com Interview with: Jessica S. Mounessa, BS University of Colorado School of Medicine Aurora, Colorado and Robert Dellavalle, MD, PhD, MSPH Professor of Dermatology and Public Health University of Colorado School of Medicine Colorado School of Public Health Chief, Dermatology Service US Department of Veterans Affairs Eastern Colorado Health Care System Denver, CO 80220  MedicalResearch.com: What is the background for this study? What are the main findings? Response: One in 10 adult cannabis users in the U.S. use it for medicinal purposes. Medicinal cannabis is well studied for its uses in chronic pain, anorexia, and nausea. Numerous recent studies have highlighted other medicinal uses for cannabinoids and related compounds. We conducted a comprehensive review of the literature on the potential role of cannabinoids in conditions affecting the skin. Our study reveals the potential benefit of topically prepared cannabinoid compounds, especially for pruritus and eczema.  For example, creams containing Palmitoylethanolamide (PEA), which enhances cannabinoid-receptor binding, have been successful in relieving itch both in the literature, and anecdotally in our clinics. Though not strictly considered an endocannabinoid, as it does not directly bind to CB1 and CB2 receptors, PEA works by enhancing endocannabinoid binding to these receptors.** Furthermore, the majority of the cannabinoid compounds we studied did not contain psychoactive effects.

Author Interviews, Cannabis, Mental Health Research, Pediatrics / 04.04.2017

MedicalResearch.com Interview with: James McIntosh PhD Economics Department Concordia University Montreal, Quebec, Canada. MedicalResearch.com: What is the background for this study Response: Marijuana is about to become legal in Canada. Consequently, an analysis of its effects on users is a high priority. This issue has been explored by Canadian researchers to some extent but there are gaps in what is known about the effects of using marijuana. Most of the Canadian studies focus on youth or adolescent use. This is clearly important but adult use is as well. Establishing the link between early usage and the effects of use over an individual’s lifetime was a major objective of the study. (more…)
Author Interviews, Cannabis, Heart Disease, Stroke / 19.03.2017

MedicalResearch.com Interview with: Aditi Kalla, MD Cardiology Research Fellow Einstein Medical Center Philadelphia MedicalResearch.com: What is the background for this study? Response: As of the recent 2016 election, decriminalization of cannabis passed in several states bringing the total count up to 28 states and D.C. where cannabis is now legal for medicinal and/or recreational purposes. From a physician’s perspective, it is rare that a drug has “hit the market” so to speak without undergoing clinical trials to determine safety and efficacy. Hence, we sought out to study if cannabis had any effects (positive or negative) on the cardiovascular system. (more…)
Addiction, Alcohol, Author Interviews, Cannabis, Mental Health Research / 03.03.2017

MedicalResearch.com Interview with: Emil F. Coccaro, M.D. Ellen C. Manning Professor Department of Psychiatry and Behavioral Neuroscience The University of Chicago Chicago, Illinois 60637 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Aggressive behavior and drug use have been related for years but this study shows people with problematic aggression (Intermittent Explosive Disorder: IED) are in fact at risk for developing alcohol, tobacco, and cannabis use disorders and that the onset of problematic aggression (IED) begins before the onset of the drug use. The increased risk for alcohol use disorder was nearly six-fold higher, the increased risk for cannabis use disorder was seven-fold higher, and the increased risk for tobacco use disorder  was four-fold higher. In addition, the presence of IED increased the severity of the substance use disorder. (more…)
Author Interviews, Cannabis, Opiods / 01.03.2017

MedicalResearch.com Interview with: Philippe Lucas VP, Patient Research & Access, Tilray Graduate Researcher, Centre for Addictions Research of BC MedicalResearch.com: What is the background for this study? Response: In 2001 Canada become one of the first nations to develop a federally regulated program to allow access to cannabis for medical purposes with the launch of the Marihuana Medical Access Regulations (MMAR). The program has undergone numerous convolutions, culminating in the establishment by Health Canada of the Marihuana for Medical Purposes Regulations (MMPR) in 2014, which was replaced by the Access to Cannabis for Medical Purposes (ACMPR) in 2016. One of the primary changes in the new program(s) has been to move from a single Licensed Producer (LP) of cannabis to multiple large-scale Licensed Producers. This is the first comprehensive survey of patients enrolled in the MMPR/ACMPR, and with 271 complete responses, it’s the largest survey of federally-authorized medical cannabis patients to date.

Addiction, Alcohol, Author Interviews, Cannabis, Education, Pediatrics, Smoking / 23.02.2017

MedicalResearch.com Interview with: Dr. James Williams UCL Medical School UCL, London, UK MedicalResearch.com: What is the background for this study? Response: Despite a downward trend over the last decade in the usage of particular substances amongst adolescents in the UK, smoking cigarettes, drinking alcohol and smoking cannabis remain prevalent behaviours in this demographic. These risky health behaviours present a large problem in terms of public health due to the immediate and long-term health problems they cause, as well as negative non-health outcomes such as poor educational attainment and reduced employment. The role of academic ability in determining patterns of substance use is not clear and no study has evaluated academic ability at age 11 in relation to the onset and persistence of all three substances from early to late adolescence and into young adulthood. Our study sought to determine the association between academic ability and the onset and persistence of substance use in adolescence in a representative sample of English school pupils. This would answer for the first time whether ability was associated with ‘experimentation’ in early adolescence or if the association persists into late adolescence. (more…)
Alcohol, Author Interviews, Cannabis / 17.01.2017

MedicalResearch.com Interview with: Kathleen K. Bucholz, Ph.D. Professor, Department of Psychiatry Washington University School of Medicine St. Louis MO 63110-1547 MedicalResearch.com: What is the background for this study? Response: We know that development of alcohol use disorder progresses through several stages of alcohol use, from beginning to drink, to engaging in problem drinking, and then to developing alcohol use disorder, but we don’t know whether the same factors are associated with each step in this progression. Stage-specific associations have implications for prevention, where targeting certain characteristics might stave off progression to the next level of alcohol involvement, potentially. That is what this particular study set out to investigate. The data were from nearly 3600 adolescents and young adults, the majority of whom came from families with alcohol use disorder in their relatives. Thus, this sample was enriched with individuals who were at high risk for progressing to more severe stages of alcohol involvement. In studying the associations at each stage, we strengthened our analysis by defining wherever possible variables as risk factors only if they occurred before or at the same age as the particular alcohol stage. For example, we counted cannabis use as a risk factor for starting to drink only if it either preceded or occurred at the same age as taking the first drink. With this definition, we can infer that a particular factor is antecedent and not simply a correlated influence. (more…)
Author Interviews, Cannabis, JAMA, Pediatrics, UC Davis / 02.01.2017

MedicalResearch.com Interview with: Magdalena Cerda, DrPH, MPH Vice Chancellor's Chair in Violence Prevention Associate Director, Violence Prevention Research Program UC Davis Violence Prevention Research Program MedicalResearch.com: What is the background for this study? What are the main findings? Response: The potential effect of legalizing marijuana for recreational use has been a topic of considerable debate since Washington and Colorado first legalized its use for adults in 2012. Alaska, Oregon and Washington, D.C., followed suit in 2014, and voters in California, Massachusetts and Nevada approved recreational use this past November. In our study, we examined changes in perceived risk of marijuana use, and in use of marijuana among school-attending adolescents, in Washington and Colorado, following legalization of recreational marijuana use, and compared pre- to post-legalization changes in these two states to changes in the 45 contiguous US states that had not legalized recreational marijuana use. Marijuana use significantly increased and its perceived harm decreased among eighth- and 10th-graders in Washington state following enactment of recreational marijuana laws. There was no change in use or perceived harm among 12th graders or among similar grades in Colorado. In particular, the data showed that legalization of recreational marijuana use significantly reduced perceptions of marijuana’s harmfulness by 14 percent and 16 percent among eighth and 10th graders and increased their past-month marijuana use by 2 percent and 4 percent in Washington state but not in Colorado. Among states without legalized marijuana use, the perceived harmfulness also decreased by 5 percent and 7 percent for students in the two grades, but marijuana use decreased by 1.3 percent and .9 percent. Among older adolescents in Washington state and all adolescents surveyed in Colorado, there were no changes in perceived harmfulness or marijuana use in the month after legalization. (more…)
Author Interviews, Cannabis, Nature, UT Southwestern, Weight Research / 19.11.2016

MedicalResearch.com Interview with: Dan Rosenbaum, Ph.D. Principal Investigator Department of Biophysics The University of Texas Southwestern Medical Center Dallas, Texas MedicalResearch.com: What is the background for this study? What are the main findings? Response: This study focuses on the structure of the human CB1 cannabinoid receptor. The CB1 protein is a membrane-embedded G protein-coupled receptor (GPCR) in the brain and peripheral tissues that responds to a variety of different compounds, including endogenous lipid messengers (‘endocannabinoids’), plant natural products (such as THC from the Cannabis sativa plant i.e. marijuana), and synthetic antagonists (such as the taranabant ligand used for this study). The CB1 receptor is involved in regulating neurotransmission in vertebrates, and is a potential therapeutic target for numerous conditions including obesity, pain, and epilepsy. The main findings of this study entailed the solution of the high-resolution crystal structure of human CB1 receptor bound to the inhibitor taranabant. This structure revealed the precise shape of the inhibitor binding pocket, which is also responsible for binding THC and endocannabinoids. In addition to helping explain the mechanism of inhibitor and THC binding, our structure provides a framework for computational studies of binding to a large diversity of cannabinoid modulators of therapeutic importance.

Author Interviews, Cannabis, Gender Differences, Heart Disease / 14.11.2016

MedicalResearch.com Interview with: Amitoj Singh MD Chief Cardiology Fellow St. Luke’s University Health Bethlehem, Pennsylvania MedicalResearch.com: What is the background for this study? Response: Marijuana use in steadily increasing and it is the most commonly used illicit drug in the US and worldwide. There has been a recent increase in reports of heart and vascular complications associated with its use. These include Myocardial infarctions, stroke and takotsubo. We had two questions that we wanted to answer with our study: a) Is there an association between marijuana use and development of Transient Regional Ventricular Ballooning [TVRB] (aka Stress Cardiomyopathy /Broken Heart Syndrome/ Takotsubo)? b) If the above is true, what are the differences between Marijuana users (MU) and Non Marijuana Users (NMU) who developed Stress Cardiomyopathy.

Alcohol, Author Interviews, Cannabis, Schizophrenia / 27.10.2016

MedicalResearch.com Interview with: Dr Stine Mai Nielsen Copenhagen University Hospital Mental Health Center Copenhagen Gentofte, Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Response: Several studies have tested whether use of substances can cause schizophrenia. However due to methodological limitations in the existing literature, uncertainties still remains. We aimed to investigate the association between several types of substance abuses and the risk of developing schizophrenia later in life. We did a nationwide, prospective cohort study using the detailed Danish registers, which enabled us to address some of the limitations from prior findings. Our cohort consisted of more than 3.13 mio. individuals, that we were able to follow up for more than 104 mio. years at risk. We found that dealing with a substance abuse increased the overall risk of developing schizophrenia by 6 times, with abuse of cannabis and alcohol presenting the highest associations (5 and 3 times increased risk). The risk was found to be significant even 10-15 years prior to a diagnosis of substance abuse. (more…)
Author Interviews, Cannabis, Cognitive Issues, Depression, Pediatrics / 12.10.2016

MedicalResearch.com Interview with: Elizabeth Osuch, M.D. Associate Professor; Rea Chair Department of Psychiatry FEMAP--London Health Sciences Centre London, ON    MedicalResearch.com: What is the background for this study? What are the main findings? Response: As a researcher and psychiatrist doing clinical work in youth aged 16-25 with mood and anxiety disorders I often see patients who are depressed and believe that using marijuana (MJ) improves their mood.  Yet they remain depressed.  This was the clinical inspiration for this brain imaging study, where we investigated emerging adults with Major Depressive Disorder (MDD).  Subject groups included patients with MDD who did and did not use MJ frequently.  Our results showed that the MDD+MJ group did not have significantly less depression than the MDD alone group, and the brain abnormalities found in MDD were not corrected by MJ use in the MDD+MJ group.  In fact, some of the brain differences were worse with the addition of MJ, while others were just different.

Accidents & Violence, Author Interviews, Cannabis, Columbia, Opiods / 17.09.2016

MedicalResearch.com Interview with: June H. Kim Doctoral candidate,Department of Epidemiology Mailman School Public Health Columbia University MedicalResearch.com: What is the background for this study? What are the main findings? Response: A previous study indicated that states with medical marijuana laws had a reduced rate of opioid overdoses. If this is true, we'd expect to see similar reductions in opioid use associated with these laws. For this study, we used data from the FARS, a national surveillance system that records any crash events on US public roads that result in a fatality. Some states provide uniform testing of the majority of their deceased drivers, year to year. Among these states, we found that there was a lower prevalence of positive opioid toxicology tests among drivers crashing in states with an operational medical marijuana versus drivers crashing in states before a future medical marijuana law is implemented, particularly among drivers aged 21-40.

Author Interviews, Cannabis, Lancet, NIH / 06.09.2016

MedicalResearch.com Interview with: Dr. Wilson Compton MD, Deputy Director National Institute on Drug Abuse MedicalResearch.com: What is the background for this study? What are the main findings? Response: The study found that overall past year marijuana use by adults in the U.S. increased by more than 30% in the past dozen years, and 10 million more people were using marijuana in 2014 than in 2002. Use of marijuana on a daily (or near daily) basis increased even more markedly. In 2002, 3.9 million adults in the U.S. reported using marijuana daily or nearly every day, and the number more than doubled to 8.4 million by 2014. Along with this increase in use, we found that U.S. adults perceptions of the potential harms from using marijuana greatly decreased. Despite scientific evidence of potential harms, adults are much less convinced about dangers associated with using marijuana. These reductions in perceived harm were strongly associated with the increases in use. (more…)

AHA Journals, Author Interviews, Cannabis, Pulmonary Disease, UCSF / 27.07.2016

MedicalResearch.com Interview with: Matthew L. Springer, Ph.D. Professor of Medicine Division of Cardiology University of California, San Francisco San Francisco, CA MedicalResearch.com: What is the background for this study? Response: We've known for many years that secondhand smoke from tobacco cigarettes is harmful, and the vast majority of deaths thought to result from secondhand smoke are from cardiovascular disease. However, very little has been known about cardiovascular consequences of exposure to secondhand smoke from marijuana, and people tend to mistake the lack of evidence that it is harmful, for evidence that is it not harmful. As a result, many people seem relatively unconcerned about smoking marijuana and being exposed (or exposing others) to marijuana secondhand smoke. Politicians and policy makers also seem less willing to limit where people can smoke marijuana (under legal circumstances) than tobacco. What has been lacking is research into how exposure to marijuana smoke affects cardiovascular health. It has been difficult to do such experiments because marijuana is illegal in the eyes of the federal government. However, we have been studying the harmful effects of secondhand tobacco smoke on the function of rat blood vessels, which is similar to its harmful effects on human blood vessels, and we now have studied how the function of rat blood vessels is affected by exposure to secondhand marijuana smoke.

MedicalResearch.com Interview with: George Sam Wang MD FAAP Assistant Professor of Pediatrics Section of Emergency Medicine, Medical Toxicology Department of Pediatrics University of Colorado Anschutz Medical Campus Children's Hospital Colorado MedicalResearch.com: What is the background for this study? Response: Many states have allowed medical and now recreational marijuana. The impact on pediatric population has not been fully described. MedicalResearch.com: What are the main findings? Response: Unintentional exposures presenting to our children's hospital and calls to our regional poison center significantly increased after our state allowed recreational marijuana. MedicalResearch.com: What should readers take away from your report? Response: Exposures in children are increasing in our state that allows medical and recreational Marijuana, many were edible products. Marijuana products should be treated like medications and household products in home and properly and safely stored. States looking to legalize marijuana need to consider safety rules and regulations during rule making processes. (more…)
Author Interviews, Cannabis, JAMA, Mental Health Research / 06.07.2016

MedicalResearch.com Interview with: Mary P. Heitzeg, PhD Assistant Professor Department of Psychiatry University of Michigan MedicalResearch.com: What is the background for this study? What are the main findings? Response: We wanted to find out if marijuana use changed the way the brain’s reward system responded to natural rewards. To probe response to natural reward, we used the chance to win some money and we observed brain response using functional magnetic resonance imaging (fMRI). We looked at brain activity when participants were 20 years old on average, and then again 2 years later and 4 years later. We found that over time marijuana use was associated with a decrease in the brain’s reward response to the chance to win money. This finding is consistent with current theories of addiction that suggest that repeated use of a substance may dampen the brain’s reward response to things normally perceived as pleasurable and this alteration may drive the individual to continue substance use.
