Smoking, Tobacco Research / 15.07.2024

We've all grown up knowing that smoking is bad for us. But beyond the basic warnings on cigarette packs, there are many myths and misconceptions about smoking that cloud the real picture. It's time to separate fact from fiction and understand the true impact of smoking on our health.

Myth: Smoking only harms your lungs

When we think about smoking, we often focus on how it affects our lungs. Sure, it's common knowledge that smoking can lead to lung cancer and breathing problems. But the truth is, smoking doesn't stop there. It affects every part of your body, from your heart to your skin. Nicotine and the chemicals in cigarettes get into your bloodstream, causing damage throughout. 

Fact: Smoking affects your whole body

Beyond the coughing and shortness of breath, smoking raises your risk of heart issues, strokes, and a host of cancers. It messes with your metabolism, weakens your immune system, and even affects your bones. It's a total body assault that goes far beyond what you see in the mirror. Smoking can also contribute to conditions like varicose veins and blood clots. Considerconsulting a vein doctor in Chattanooga to learn more about how smoking affects circulation and vein health.

Author Interviews, JAMA, Smoking, Tobacco, Tobacco Research, UC Davis / 05.08.2021

MedicalResearch.com Interview with: John Pierce, PhD Professor Emeritus Department of Family Medicine and Public Health Moores Cancer Center Director for Population Sciences Co-leader of the Cancer Prevention program UC San Diego MedicalResearch.com: What is the background for this study? What are the main findings? Response: Graphic Warning Labels are to be implemented in the US in July 2022, depending on litigation. This will be about 10 years after they were first proposed.  Meanwhile, 120 other countries have implemented them already. The FDA states that their purpose for the warnings is to provide a constant reminder to smokers about the health consequences of smoking, not to force them to quit. In our study, 3 months of having cigarettes repackaged into graphic warning packs was associated with smokers thinking more about quitting and not getting as much pleasure out of their cigarettes.  However, thinking about quitting is only the first step to conquering a nicotine addiction.

MedicalResearch.com Interview with: Dr. Michael Silverstein M.D., M.P.H Professor of Pediatrics Director of the Division of General Academic Pediatrics Vice Chair of Research, Department of Pediatrics Boston University School of Medicine  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Tobacco use is the leading preventable cause of disease, disability, and death in the United States and quitting is one of the best things people can do for their health. Additionally, smoking during pregnancy can cause serious harms to both the pregnant person and the baby. The Task Force continues to recommend that clinicians ask all adults and pregnant people about their tobacco use, advise those who use tobacco to quit, and connect them to proven, safe methods to help them quit.  (more…)

MedicalResearch.com Interview with: Dongmei Li, Ph.D., Associate Professor Clinical and Translational Science Institute University of Rochester Medical Center MedicalResearch.com: What is the background for this study? Response: Previous animal and human studies have found that nicotine exposure could harm adolescents’ brain development and impact their cognitive functions. Electronic cigarettes, which have become very popular among youth in the US in recent years, usually contain nicotine at equivalent or possibly higher levels than traditional tobacco cigarettes. Thus, it is reasonable to assume that vaping might be associated with self-reported cognitive complaints. MedicalResearch.com: What are the main findings?  Response: Main findings from our study are:
  1. Our cross-sectional youth and adult studies are the first to associate vaping with self-reported complaints of serious difficulty concentrating, remembering, or making decisions.
  2. Our youth study also found that students who reported starting to vape early – between eight and 13 years of age – had higher odds of reporting difficulty concentrating, remembering, or making decisions than those who started vaping at 14 or older.
  3. These studies add to a growing list of conditions and diseases (wheezing, COPD, cardiovascular disease, cancer) that have been associated with vaping/electronic cigarette use.

MedicalResearch.com Interview with: Bonnie Halpern-Felsher, PhD, FSAHM (pronouns: she/her) Professor of Pediatrics Taube Endowed Research Faculty Scholar Professor (by courtesy), Epidemiology and Population Health Professor (by courtesy), Psychiatry and Behavioral Sciences Director of Fellows’ Scholarship, Department of Pediatrics Director of Research, Division of Adolescent Medicine Co-leader, Scholarly Concentrations, Pediatrics Residency Program MedicalResearch.com: What is the background for this study? What are the main findings? Response: To examine adolescent and young adult e-cigarette use during the COVID-19 pandemic. There were 4 main findings:
  • About 2/3 of adolescent and young adult ever-e-cigarette users reported either quitting or cutting back on e-cigarette use since COVID-19 began.
  • Users least likely to quit or cut back e-cigarette use were those showing higher levels of nicotine dependence and those who had used e- cigarettes a large number of times.
  • Adolescent and young adult e-cigarette users found it harder to access e-cigarettes, but unlike studies before COVID-19, the dominant source of purchasing e-cigs was online instead of brick-and-mortar during COVID-19 pandemic.
  • Youth below 21 years were able to purchase e-cigarettes without any age verification, and those whose age was verified were asked to physically show ID or provided an email, which are less effective means to prevent underage youth use.

MedicalResearch.com Interview with: Mahmoud Al Rifai, MD, MPH Cardiovascular Disease Fellow Baylor College of Medicine Houston, TX Salim S. Virani, MD, PhD, FACC, FAHA, FASPC Professor, Section of Cardiovascular Research Director, Cardiology Fellowship Training Program Baylor College of Medicine Staff Cardiologist, Michael E. DeBakey Veterans Affairs Medical Center Co-Director, VA Advanced Fellowship in Health Services Research & Development at the Michael E. DeBakey VA Medical Center Investigator, Health Policy, Quality and Informatics Program Michael E. DeBakey Veterans Affairs Medical Center HSR&D Center of Innovation Houston, TX MedicalResearch.com: What is the background for this study? What are the main findings? Response: E-cigarettes have gained popularity since their introduction in the U.S. market nearly 20 years ago and their use has increased especially among younger adults. On the other hand, public health efforts aimed at curbing tobacco use over the past few decades have resulted in a decrease in cigarette use. However, state-specific laws and regional cultural differences with regards to perception of these products may result in variability in tobacco use patterns. We therefore evaluate temporal changes in e-cigarette and cigarette use in each U.S. state between the years 2016 to 2018. (more…)

MedicalResearch.com Interview with: Irfan Rahman, Ph.D. Principal Investigator. Center for Inhalation and Flavoring Toxicological Research University of Rochester MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our study aimed to determine whether vaping and smoking affect Covid-19 proteins and genes and whether that effect changes depending on the age of the vaper/smoker. SARS-Cov-2, the virus that causes Covid-19, enters cells by interacting with ACE2 and TMPRSS2-Furin proteins. We found that both of these proteins increase with age and are also increased by smoking or vaping. This suggests that older adults, smokers and vapers may be more prone to infection with SARS-Cov-2 and may be more likely to have severe complications. (more…)
Author Interviews, JAMA, Smoking, Tobacco, Tobacco Research / 21.11.2019

MedicalResearch.com Interview with: Amy L. Nyman, MA Research Associate Georgia State University, School of Public Health Atlanta, GA 30303 Coauthors: Nyman, Huang, Weaver, Eriksen MedicalResearch.com: What is the background for this study? Response: Though the negative health consequences of smoking combustible cigarettes have been well-established and widely accepted, there has been significant public debate about the health effects of Electronic Nicotine Delivery Systems (ENDS) use, and the extent to which use of ENDS may present less health risk to smokers than smoking combustible cigarettes. Many tobacco control researchers and scientists believe that ENDS use is safer than combustible cigarette smoking, though recent news of an expansive outbreak of vaping-related lung illnesses and deaths has led to continued speculation. A prior study of perceived comparative harm of combustible cigarettes and ENDS revealed the proportion of US adults perceiving ENDS to be as harmful as, or more harmful than combustible cigarettes increased substantially between 2012 and 2017. Given recently proposed regulations and the escalating focus on the impact of ENDS use on youth in the past few years, our study assessed changes in perceived comparative harm of combustible cigarettes and ENDS among US adults since the prior study, between 2017 and 2018.  (more…)

MedicalResearch.com Interview with: Melody Kingsley, MPH Epidemiologist, Massachusetts Department of Public Health  MedicalResearch.com: What is the background for this study? Response: The majority of youth who use tobacco use flavored products, which are available in thousands of distinct flavors with youth appeal.[i] In response, communities in states across the country, including Massachusetts, have passed flavored tobacco restriction policies which restrict sales of flavored tobacco; the Food and Drug Administration has proposed increased restrictions on the sale of flavored tobacco nationwide as well. To date, a few studies have found that flavored tobacco restriction policies reduce sales and availability of flavored tobacco, but to our knowledge, no prior evidence exists on the short-term impact of FTRPs on youth tobacco use. Timely evaluation of these policies is important to ensure that FTRPs are an effective strategy for curbing youth tobacco use. (more…)

MedicalResearch.com Interview with: Andrea Villanti, PhD, MPH Associate Professor Department of Psychiatry Vermont Center on Behavior and Health University of Vermont  MedicalResearch.com: What is the background for this study? Response: Our earlier work documented a significant association between first use of a flavored tobacco product and current tobacco use (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5522636/) in a cross-sectional sample. The goal of this study was to examine whether there was a prospective relationship between first use of a flavored tobacco product and subsequent use of that product in longitudinal data..  (more…)
Author Interviews, Heart Disease, Pediatrics, Smoking, UCSF / 23.09.2019

MedicalResearch.com Interview with: Gregory M Marcus, MD, MAS Professor of Medicine in Residence Endowed Professor in Atrial Fibrillation Research University of California, San Francisco Associate Chief of Cardiology for Research, UCSF Health University of California, San Francisco MedicalResearch.com: What is the background for this study? What are the main findings? Response: Smoking remains the most common preventable cause of death and disability. We previously found evidence that tobacco smoke exposure in the young may lead to atrial fibrillation, the most common heart rhythm disturbance, later in life. Here we leveraged the multi-generational nature of the Framingham Heart Study to demonstrate that parental smoking was a risk factor for offspring atrial fibrillation. At least some of this relationship was explained by a greater propensity to smoke in offspring of smoking parents. These findings demonstrate a potentially new harmful effect of smoking pertinent to the most vulnerable population, our children. It also demonstrates how parental behaviors can have meaningful adverse consequences to their children decades later. (more…)

MedicalResearch.com Interview with: Hongying (Daisy) Dai, PhD Associate Professor Department of Biostatistics | College of Public Health University of Nebraska Medical Center Omaha MedicalResearch.com: What is the background for this study? Response: Previous studies have reported a surge in e-cigarette use among youth during the 2017 - 2018. For instance, the prevalence of current (past 30-day) e-cigarette use increased by 77.8% (from 11.7% to 20.8%) among high school students and by 48.5% (from 3.3% to 4.9%) among middle school students. As a result, the Food and Drug Administration (FDA) warns that youth e-cigarette use is reaching an epidemic proportion in September 2018. Whether e-cigarette use prevalence also increased among young adults (aged 18-24 years), a population with high e-cigarette use rates and vulnerability to nicotine dependence, is unknown. (more…)

MedicalResearch.com Interview with: Sairam Jabba, Ph.D Senior Research Associate Department of Anesthesiology Duke University Durham, NC 27710 MedicalResearch.com: What is the background for this study? Response: Pulegone is a potential carcinogen contained in several mint oils. Due to its carcinogenic properties, FDA banned pulegone last year as a food additive. Previous chemical analytical studies from CDC have demonstrated that several mint/menthol-flavored e-cigarette liquids and snuff tobacco products contain pulegone in significant amounts. FDA currently does not regulate pulegone in e-cigarettes and snuff products and the health risk associated with it for the users is not well understood.  (more…)
Author Interviews, Smoking, Tobacco, Tobacco Research, Yale / 26.07.2019

MedicalResearch.com Interview with: Abigail S. Friedman, Ph.D. Assistant Professor Department of Health Policy and Management Yale School of Public Health   MedicalResearch.com: What is the background for this study? Response: Smoking is responsible for approximately 1 in 5 deaths in the United States each year. Despite the fact that all US states ban tobacco sales to minors, the vast majority of smokers begin this habit as adolescents. As of July 25, 2019, 18 states and over 450 localities have passed laws banning tobacco sales to those under age-21. The laws are commonly referred to as “tobacco-21” laws. Concurrently, 16 states without state-level tobacco-21 laws prohibit counties and municipalities from raising their legal sales age for tobacco products above the state-mandated age; typically, 18. If local tobacco-21 laws reduce youth smoking, then preemption policies impede population health. To consider this, we estimated the impact of county- and municipality-level tobacco-21 policies on smoking among 18 to 20 year-olds residing in MMSAs (metropolitan and micropolitan statistical areas). Specifically, regression analyses compared smoking among 18-20 year-olds in areas with more vs. less tobacco-21 coverage, before vs. after these policies were adopted. (more…)

MedicalResearch.com Interview with: Ian A. Maher, MD Department of Dermatology St Louis University, St Louis, Missouri  MedicalResearch.com: What is the background for this study? What are the main findings? Response: One of our wonderful trainees at Saint Louis University was interested in the role of smoking in flap failures.  Dogma has been that smoking was a major risk factor for flap failures.  Looking at our database as well as published data, flap failures are a rare event, so rare as to be difficult to definitively associate with anything.  We decided to look more broadly at complications both acute (infections failures) and chronic (mainly cosmetic scarring associated) in flaps and grafts.

Abdel Magid, MHS, PhDPostdoctoral ScholarDepartment of Health Research & PolicyStanford UniversityHoda S. Abdel Magid, MHS, PhD Postdoctoral Scholar Department of Health Research & Policy Stanford University MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Dr. Hoda Magid, my former graduate student, and I wanted to examine whether owning promotional items for e-cigarettes and other non-cigarette products predicted youth use of those products.  Other studies have examined whether ownership of coupons, samples, and other promotional materials influenced cigarette use, but no longitudinal study examined other tobacco products. Our findings show that non-tobacco using youth who own items to promote e-cigarettes and other alternative tobacco products are twice as likely to use alternative tobacco products a year later.

What are the main findings? Response:  Although e-cigarette aerosols are commonly perceived to be "harmless water vapors" they contain numerous potentially harmful chemicals including volatile organic compounds like formaldehyde, nicotine, heavy metals, and ultrafine particulates. Non-users can be exposed to these chemicals through secondhand exposure. We found that in the US 4.9% of adults who lived in a household with children were current e-cigarette users. (more…)
Addiction, Author Interviews, Cannabis, Pediatrics, Smoking, Tobacco, Tobacco Research / 30.04.2019

MedicalResearch.com Interview with: Joan S. Tucker, Ph.D. Senior Behavioral Scientist RAND Corporation Santa Monica, CA MedicalResearch.com: What is the background for this study?   Response: In light of young adults’ expanding access to cannabis through legalization for recreational use, there has been growing interest in the co-use of cannabis with tobacco/nicotine products.  Although existing data show that young adults who use cannabis products also tend to use tobacco/nicotine products, little is known about how these products are typically used together. Existing research on co-use has mostly focused on combustible products, not accounting for the recent proliferation in cannabis and tobacco/nicotine product types and methods of use (e.g., vaping). Further, not much is known about whether there are important differences between types of co-use (e.g., using both products on the same occasion, one right after another, but not mixing them vs. using both products by mixing them in the same delivery device) in terms of heaviness of use, consequences from use, or associations with young adult functioning. This study was designed as an important first step toward understanding cannabis and tobacco/nicotine co-use behavior among young adults and addressing these gaps in the research literature. (more…)

MedicalResearch.com Interview with: Jidong Huang, PhD Associate Professor Department of Health Policy & Behavioral Sciences School of Public Health, Georgia State University Atlanta, GA 30303 MedicalResearch.com: What is the background for this study?   Response: The US tobacco market has been transformed in the past decade by a rapid increase in awareness and use of e-cigarettes among youth and adults. This transformation has been accelerated in recent years by the emergence of new generations of e-cigarettes, such as JUUL e-cigarettes. The exponential growth in e-cigarettes has prompted a renewed interest in the tobacco harm reduction approach, which aims to rapidly curbing the smoking epidemic by encouraging smokers to switch to low risk tobacco products, such as e-cigarettes. There is an ongoing debate about whether the scientific evidence on the health risks of e-cigarettes in comparison with combustible cigarettes has been accurately communicated to the public. Large representative surveys are needed to examine how the public perceives the health risk of e-cigarettes and how their perception change over time. (more…)

MedicalResearch.com Interview with: Dennis Drayna, PhD Chief of the Laboratory of Communication Disorders and the Section on Genetics of Communication Disorders National Institute on Deafness and Other Communication Disorders Part of the National Institutes of Health MedicalResearch.com: What is the background for this study? Response: In the United States, there are striking racial differences in the rate of menthol cigarette use.  Tobacco use is a major preventable source of morbidity and mortality in the population, and menthol cigarette use by African Americans represents an important issue for attempts to address minority health disparities. There have been many studies that have documented the role of inherited factors that contribute to smoking or tobacco use.  However, no studies have examined the role of genetic factors specifically in menthol tobacco use.  The preference for menthol cigarettes among African Americans has previously been attributed to cultural factors or industry advertising practices directed at this group. In our study, we asked whether genetic factors could explain why African-American smokers choose menthol cigarettes over non-menthol cigarettes. Our initial hypothesis was that variation in genes that encode the known menthol receptors was important in this difference, although we designed our study to look at all 21,000 protein-coding genes in the genome.

MedicalResearch.com Interview with: Eric Leas PhD, MPH Stanford Prevention Research Center University of California, San Diego MedicalResearch.com: What is the background for this study? What are the main findings? Response: Recent research has demonstrated the importance that neighborhood context has on life opportunity, health and well-being that can perpetuate across generations. A strongly defining factor that leads to differences in health outcomes across neighborhoods, such as differences in chronic disease, is the concurrent-uneven distribution of modifiable risk factors for chronic disease. The main goal of our study was to characterize inequities in smoking, the leading risk factor for chronic disease, between neighborhoods in America's 500 largest cities. To accomplish this aim we used first-of-its-kind data generated from the 500 Cities Project—a collaboration between Robert Wood Johnson Foundation and the US Centers for Disease Control and Prevention—representing the largest effort to provide small-area estimates of modifiable risk factors for chronic disease. We found that inequities in smoking prevalence are greater within cities than between cities, are highest in the nation’s capital, and are linked to inequities in chronic disease outcomes. We also found that inequities in smoking were associated to inequities in neighborhood characteristics, including race, median household income and the number of tobacco retailers.  (more…)
Author Interviews, JAMA, Pediatrics, Smoking, Tobacco, Tobacco Research / 07.01.2019

MedicalResearch.com Interview with: Dr. Hongying Dai, PhD Associate Professor at the College of Public Health University of Nebraska Medical Center. MedicalResearch.com: What is the background for this study? Response: The 2009 Family Smoking Prevention and Tobacco Control Act (FSPTCA) banned cigarettes with characterizing flavors (e.g., candy, fruit, clove) except menthol. However, there are no restrictions on the marketing and sales of flavored non-cigarette tobacco products. This has led to a proliferation of flavored tobacco products in the marketplace. Flavoring has become one of the leading reasons for current tobacco use among youth. It is reported that 81% of e-cigarette users, 79% of hookah users, 74% of cigar users, 69% of smokeless tobacco users, and 67% of snus users attributed the availability of appealing flavors for their tobacco use in 2013–2014 among teenagers aged 12 to 17 years. In November 2018, the FDA proposed new restrictions on flavored tobacco products. (more…)
Author Interviews, NEJM, Pediatrics, Smoking, Tobacco, Tobacco Research, University of Michigan / 30.12.2018

MedicalResearch.com Interview with: Richard Miech Ph.D Professor Principal Investigator, Monitoring the Future Institute for Social Research University of Michigan MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Every year Monitoring the Future conducts a survey to examine trends in adolescent substance use.  We draw a random sample of schools from a list of all schools in the United States and conduct our survey in ~400 schools.  Our survey is representative of U.S. 8th, 10th, and 12th grade students.  In other words, our results are what you would find if you surveyed every single 8th, 10th, and 12th graders in the United States, within the bounds of a small sampling error of a few percentage points. An increase in vaping is the big news for 2018.  In 10th and 12th grade the increase in nicotine vaping was the largest we've ever seen for any substance in the past 43 years.  As a result of this increase in nicotine vaping, overall use of nicotine increased as well, which suggests that vaping is drawing youth into nicotine use.  We also saw a significant increase in marijuana vaping.

Alcohol, Author Interviews, Smoking / 28.12.2018

MedicalResearch.com Interview with: Dr. Sarah Dermody, PhD Assistant Professor School of Psychological Science Oregon State University Corvallis Oregon  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Drinking alcohol is a risk factor for sustained smoking. In a sample of daily cigarette smokers receiving treatment for alcohol use disorder, we examined if reductions in drinking corresponded with reductions in nicotine metabolism as indexed by the nicotine metabolite ratio. The nicotine metabolite ratio is important because it is associated with smoking level and lapses. We found that for men, alcohol use and the nicotine metabolite ratio reduced significantly; however, for women, neither drinking nor nicotine metabolite ratio changed. (more…)

MedicalResearch.com Interview with: Nis Brix M.D., PhD Student Department of Public Health Department of Epidemiology Aarhus University Hospital Nis Brix M.D., PhD Student Department of Public Health Department of Epidemiology Aarhus University Hospital  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Several studies have indicated a secular trend towards earlier puberty. This is a potential concern as early puberty has been linked to an increased risk of a number of diseases, such as obesity, diabetes, cardiovascular diseases and certain types of cancer. For this reason, our research team are interested in identifying potential modifiable causes of early puberty. Smoking during pregnancy may be such a modifiable cause of early puberty in the children. Former studies have already linked smoking during pregnancy to earlier age at the daughters’ first menstrual period, a relatively late marker of pubertal development, but other markers of puberty are less studied, especially in the sons. We studied 15,819 sons and daughters. The mothers gave detailed information on smoking during their pregnancies, and the children gave information on a number of pubertal milestones half-yearly from the age of 11 years. The milestones for the sons were age at voice break, first ejaculation of semen, pubic hair and testicular growth, armpit hair growth and onset of acne. For the daughters the milestones were age at their first menstrual period, pubic hair growth, breast development, armpit hair growth and onset of acne. Our results suggested that the more cigarettes the mother smoked during her pregnancy the earlier her children, both sons and daughters, went through puberty. If the mother smoked more than ten cigarettes a day during pregnancy, the children appeared to go through puberty, on average, three to six months earlier than the children of non-smoking mothers.

MedicalResearch.com Interview with: Pr Gilles Boire, M.D., M. ScService de rhumatologie Département de médecine Faculté de médecine et des sciences de la santé Université de Sherbrooke MedicalResearch.com: What is the background for this study? Response: Rheumatoid arthritis (RA) patients are heterogeneous at initial presentation, in response to treatments and according to their outcomes. No clinical features and very few biomarkers, except autoantibodies such as anti-Cyclic Citrullinated Peptides/Proteins (CCP), identify patients with divergent prognostic trajectories. To help improve early prognostic classification, we initiated 20 years ago the single center longitudinal observational Early Undifferentiated PolyArthritis (EUPA) study of consecutive patients presenting with recent-onset inflammatory polyarthritis, 90% of which fulfill classification criteria for RA at baseline. Our registry includes 739 very early RA patients (median symptom duration 3.6 months), rapidly treated to joint remission (i.e. 0/66 swollen joint) and followed over 5 years. Each patient visit is linked to biosamples and to sequential radiographs scored according to the modified Sharp/van der Heijde method. As we had the clinical impression that clinical features of recruited patients were evolving, we compared patients from 3 periods (1998-2004; 2005-2010; 2011-2017).  (more…)

Bhide, Ph.D. Professor | Jim and Betty Ann Rodgers Eminent Scholar Chair of Developmental Neuroscience Director, Center for Brain Repair Department of Biomedical Sciences Florida State University College of Medicine Tallahassee, FL MedicalResearch.com: What is the background for this study? What are the main findings? Response: Until now, much attention had been focused on the adverse effects of cigarette smoking by pregnant women on their children’s cognitive development. Some reports suggested that cigarette smoking during pregnancy can produce harmful effects in multiple generations of descendants (transgenerational effects). Not much had been known about the effects of paternal smoking, although more men smoke cigarettes than women. Our study shows that paternal nicotine exposure can be deleterious to the offspring in multiple generations. That is, cognitive function may be compromised in children and grandchildren of a nicotine-exposed male. Of course, our study was done in mice and not men.  However, since studies done in mice on maternal nicotine exposure produced results consistent with studies done in women and children, we believe that he findings from our present study likely can be extrapolated to humans.  (more…)

MedicalResearch.com: What is the background for this study? Response: E-cigarettes were introduced first in US market as a less harmful method of nicotine delivery which potentially would help smokers to have a less harmful option. However, overtime e-cigarette found its niche of consumers in the younger/tobacco naïve population. Our study is amongst the first studies that describes those who use e-cigarette without any history of combustible-cigarette smoking.  (more…)
