Tobacco Research

Notice: Vaping and e-cigarette products contain nicotine, which is highly addictive. They are not approved by the FDA as cessation devices and are not recommended for non-smokers, pregnant individuals, or anyone under 21. If you do not currently smoke, do not start vaping. If you smoke and are considering switching or quitting, speak with a qualified healthcare provider about all available options, including FDA-approved cessation aids. This article is for informational purposes only.

The conversation about vaping has, for most of the last decade, run on a research track and a consumer track that didn't quite meet. The research track measured what specific devices did to specific populations under specific conditions. The consumer track evolved faster than the research could keep up with. What's changing in 2026 is that a third track — what vape users themselves are demanding — has started to shape the market in ways that research and regulation, on their slower clocks, haven't. The result is a faster pull toward transparency, third-party testing, and ingredient disclosure than either evidence-based or rule-making alone had produced.

What follows is a look at where those three tracks are converging: what the research has actually established, what the consumer market looks like now, what vape users themselves are asking for, and what the answer to all three together means for the conversation a clinician or current adult smoker is most likely to be having.

By age 16, 38% of participants reported having used at least one substance during their lifetime. Alcohol, cannabis and nicotine were the substances most commonly reported.</p> <p style="font-family:Georgia,serif;font-size:18px;line-height:1.8;color:#1a1a2e;">The researchers also identified differences by sex. Boys reported higher rates of substance use before age 12, but beginning around age 13, girls reported higher rates of alcohol, cannabis and nicotine use, with the largest differences seen for nicotine. Polysubstance use — using two or more substances — was also relatively common, with nearly 15% of participants reporting it during the study. The most common combination was nicotine and cannabis, and girls reported higher rates of polysubstance use after age 13, particularly combinations involving nicotine.</p> <p style="font-family:Georgia,serif;font-size:18px;line-height:1.8;color:#1a1a2e;">Importantly, estimates adjusted to better reflect the U.S. population were very similar to the study's unadjusted estimates, suggesting that the ABCD cohort provides a useful representation of national patterns of adolescent substance use.</p> <p style="font-family:Georgia,serif;font-size:18px;line-height:1.8;color:#1a1a2e;"><strong><em>MedicalResearch.com: What should readers take away from your report?</em></strong></p> <p style="font-family:Georgia,serif;font-size:18px;line-height:1.8;color:#1a1a2e;"><strong><em>Dr. Sullivan:</em></strong> The key takeaway is that substance use becomes increasingly common as young people move through adolescence, highlighting the importance of prevention and early intervention before or during the early teen years. The findings also show that substance use does not follow the same pattern for everyone. In particular, the shift toward higher rates of use among girls beginning around age 13 and the prevalence of nicotine-cannabis co-use point to the need for prevention strategies that account for differences in age, sex and patterns of substance use.</p> <p style="font-family:Georgia,serif;font-size:18px;line-height:1.8;color:#1a1a2e;">These findings also provide an important national benchmark for future research.

Additional research should examine the factors associated with polysubstance use, particularly nicotine and cannabis co-use, and determine whether using multiple substances is associated with different developmental or health outcomes than using a single substance. Future studies could also explore how family environment, peer relationships, mental health, social conditions and changing perceptions of substance-related risks influence when and how adolescents begin using substances.</p> <p style="font-family:Georgia,serif;font-size:18px;line-height:1.8;color:#1a1a2e;"><strong><em>MedicalResearch.com: Is there anything else you would like to add?

Dr. Sullivan: Adolescence is a critical period for brain development and a time when many young people begin experimenting with alcohol, cannabis, nicotine and other substances. Understanding when substance use begins, how it changes as young people get older, and which substances are most commonly used together can help researchers identify opportunities for prevention and better understand how early substance use may relate to later health outcomes. This study used data from the Adolescent Brain Cognitive Development (ABCD) Study, one of the largest longitudinal studies of youth in the United States, to provide an updated picture of substance use patterns from late childhood through mid-adolescence. Related MedicalResearch.com research has also found that cognitive brain circuits are altered in youth with significant cannabis use — underlining why tracking when and how adolescents begin using substances matters for understanding long-term neurodevelopmental outcomes.

Common examples include caffeine, nicotine, and amphetamines. This article explores how these compounds activate the brain’s reward pathway and produce effects that can range from a gentle lift in mood to an intense short-lived “buzz” that reinforces repeated use.

Understanding the Reward Pathway

 The brain’s reward pathway, known as the mesolimbic dopamine system, involves key regions such as the ventral tegmental area, nucleus accumbens, and prefrontal cortex. This network reinforces pleasurable behaviors by releasing dopamine which is a neurotransmitter linked to motivation and reward.  While natural activities like eating or socializing activate this system moderately, stimulants can hijack it. These trigger a much stronger and faster dopamine release. This heightened response can make the experience more compelling that encourages repeated use and increases the potential for dependence over time.

Editor's note:  Tobacco in any form is harmful to your health.  Please discuss your use of tobacco products, including vaping, with your health care provider.  [caption id="attachment_69305" align="aligncenter" width="500"]Understanding the Vaping Landscape Photo by Sabrina Rohwer:[/caption] The popularity of vaping products has surged in recent years, with flavored disposable vapes especially dominating shelves and online marketplaces. While these products are often marketed as smoother, more palatable alternatives to traditional cigarettes, the long-term health effects remain unclear. As researchers work to better understand the impact of vaping on respiratory and cardiovascular health, there’s growing pressure to also examine the behavioral and chemical patterns surrounding use.

The Role of Flavors in Usage Patterns

One of the more controversial elements of vaping is flavor availability. Products like fruit, menthol, and candy-inspired disposable vapes are particularly popular. A glance at the range of options shows how expansive and accessible these flavored products are. This variety in taste profiles plays a significant role in shaping user behavior. Many people who might otherwise avoid traditional tobacco products find the flavored alternatives more approachable. Public health experts worry that this may normalize nicotine use in broader demographics, leading to a cycle of regular consumption and potential health risks over time.

Living with Peripheral Artery Disease (PAD) can be challenging. But, there are practical lifestyle changes that can significantly improve your quality of life. This article explores how your diet, exercise, and quitting smoking can help you manage PAD symptoms.

Understanding PAD

PAD affects the arteries outside the brain and heart, usually in the legs. This happens due to plaque buildup. This narrowing restricts blood flow, causing symptoms like: - Leg pain - Cramping - Ulcers Recognizing these symptoms is key for early detection and management. Consult an interventional radiologist for accurate diagnosis and reduced pain treatment plans.

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

[caption id="attachment_62305" align="alignleft" width="200"]smoking-tobacco_pexels-iriser-798124 Image Source[/caption] 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.

The FDA regulates the manufacturing and distribution of e-cigarette and vape products in the United States, but anti-vaping laws are still heavily dependent on each state. Concerns over vaping’s impact on health, especially for youth, led many states and regions to restrict access to vape and e-cigarette products. Unlike cigarette, vapes are harder to detect. This creates a challenge when enforcing no-vape policies and anti-vape laws. Vape smoke cannot be detected through a regular smoke detector. They also do not contain a smell the way that cigarette smoke does. Both challenges make it easier for people who vape to use their products discreetly, even when inside. Youth Vaping in the U.S.: A Cause for Concern  vaping-e-cig-smoking-tobaccoYouth vaping is on the rise. The 2022National Youth Tobacco Survey (NYTS) reported that over 2.5 million youth in the U.S. use e-cigarettes. This epidemic has drawn serious health concerns across the United States. Aside from the nicotine’s addictive properties in e-cigarette and vape products, these products can also hinder brain development in youth and increase risks of cancer and lung disease. But, combatting the youth vaping issue has proved difficult. The youth attraction to flavored vaping products has contributed significantly to the vaping epidemic. It has even led to lawsuits, such as the JUUL settlement, in which vape and e-cigarette companies have been accused of using marketing tactics to make their products appeal to minors.

Spokane, WA 99210 Dr. Lazarus[/caption] Philip Lazarus, PhD Boeing Distinguished Professor, Pharmaceutical Sciences Professor, Dept of Pharmaceutical Sciences College of Pharmacy and Pharmaceutical Sciences Washington State University Spokane, WA 99210   MedicalResearch.com: What is the background for this study? Response: Smoking and tobacco use remains a major health issue. Smokers use cigarette over the course of the day because the levels of nicotine, the addictive agent in cigarettes and other forms of tobacco, dimmish with time in the bloodstream due to the breakdown of nicotine by enzymes in the body. By inhibiting the breakdown of nicotine in smokers, one would expect that the levels of nicotine would remain higher after smoking a single cigarette, and that these individuals may not require lighting up another cigarette so quickly, reducing the number of cigarettes smoked over the course of a day. This could have a profound effect on reducing the overall harm incurred from smoking or from using other forms of tobacco. In a single previous study, smokers who used a CBD inhaler exhibited a 40% reduction in cigarette use. In addition, while cannabis users are often smokers, previous studies have indicated that they smoke less cigarettes than non-cannabis-using cigarette smokers. In previous studies published in 2021, we found that major cannabinoids present in cannabis like THC and CBD inhibit major metabolizing enzymes in our body, including several that are important in drug metabolism. We hypothesized that CBD and its major active metabolite, 7-hydroxy (OH)-CBD, may also be inhibiting one or more of the enzymes important in the metabolism (or breakdown) of nicotine.

MedicalResearch.com: What is the background for this study? Response: Tobacco use landscape has been changing in the United States with fewer combustible cigarette smokers and more e-cigarette and other emerging tobacco users. Nicotine concentration level is a key product characteristic of modern e-cigarette products and high-nicotine vaping devices have recently become available. This study seeks to examine whether biomarkers of exposure to tobacco-related toxicants have changed since 2013 among adult nicotine e-cigarette users, non-nicotine e-cigarette users, and cigarette smokers.

Considering the increased popularity of e-cig use, especially among teenagers and young adults, and the known effect of high nicotine concentration in e-cigarette products, we conducted this clinical research to see if there were differences in periodontal health between e-cig users, traditional smokers, and nonsmokers. The study consisted of two visits, 6 months apart, where measures of oral and periodontal health were obtained. Our data showed significantly greater clinical attachment loss in the e-cigarette users and cigarette smokers than in the non-smokers at both study visits. In only e-cigarette users, we observed an over 0.2 mm average increase in the clinical attachment loss after 6 months.

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.

Response: The COVID-19 pandemic has been associated with mental health stressors, including anxiety, loneliness, and social instability. We hypothesized the pandemic may have led to increased alcohol and tobacco use as a coping mechanism for these stressors. National retrospective questionnaires had suggested higher reports of substance use, but these are limited by selection and recall biases, in addition to subjective report – we sought to address this knowledge gap by using a nationally-representative longitudinal cohort (Nielsen National Consumer Panel) tracking real-time purchases of households across the US.

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.

  • 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.

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.

What are the main findings? “Checking your phone and vaping as you do” by Alper Çuğun is licensed under CC BY 2.0 Response: The background for this study involves the associations of household rules and parental awareness with youth tobacco use using data from the Population Assessment Tobacco and Health Study. Health concerns regarding non-cigarette tobacco products, specifically e-cigarettes, have been on the rise. We wanted to explore whether parents are up to date with the trends of popular tobacco products today and what role they may play in youth tobacco cessation and prevention. The main findings of the study revealed that parents less often suspected their children’s tobacco use if their children reported using only e-cigarettes, and other non-cigarette tobacco products, when compared with cigarettes. Additionally, we found that youth who agreed with their parents that their home has strict rules for tobacco use were less likely to initiate of tobacco use compared to youth who had different understanding of the rules from their parents or youth from households with more permissive household rules.

Response: This is the first study to examine both nicotine vaping and cannabis vaping trajectories across adolescence and young adulthood, which allowed us to assess whether poly-substance vaping is common among adolescents and young adults. Poly-substance vaping (nicotine and cannabis vaping) was reported among a significant proportion of participants in the study (25% were identified as poly-substance vapers). For those that either escalated to frequent nicotine vaping use in adolescence or initiated frequent nicotine vaping use in young adulthood, the probability of engaging in cannabis vaping was very high (85%+).

Response: Trends in e-cigarette prevalence and population count of users according to cigarette smoking histories are unknown. These data are needed to inform public health actions against a rapidly changing U.S. e-cigarette market.

MedicalResearch.com Interview with: [caption id="attachment_55390" align="alignleft" width="200"]Irfan Rahman, Ph.D. Principal Investigator. Center for Inhalation and Flavoring Toxicological Research University of Rochester Dr. Rahman[/caption] 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.

Response: E-cigarettes are conceived by many individuals to be less harmful than combustible cigarettes, resulting in their use among young individuals and other vulnerable subpopulations. The recent outbreak of EVALI (e-cigarette, or vaping, product-use associated lung injuries) which was directly associated with e-cigarette use, and the rapidly evolving e-cigarette market, as well as regulations concerning them necessitates the need for up-to-date analyses of e-cigarette use trends. 

MedicalResearch.com Interview with: Susan Hocevar Adkins, MD Lead Author, Senior Medical Officer, and Commander United States Public Health Service CDC MedicalResearch.com: What is the background for this study? Response: Since August 2019, the Centers for Disease Control and Prevention (CDC), the US Food and Drug Administration (FDA), and state, local, and territorial health departments have been investigating a national outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI). Although clinical presentation and outcomes of EVALI patients generally have been reported, data on adolescent patients are more limited. This article fills this gap by using data from national EVALI surveillance at CDC to examine demographic, substance use, and clinical characteristics of adolescent EVALI patients relative to young adult and adult EVALI patients.

Response: The number of children and teens who use tobacco products continues to be a major issue in the U.S., driven largely by an increase in e-cigarette use, which makes preventing tobacco use among young people critical to the health of our nation. To help prevent kids and teens from starting to use tobacco, the Task Force recommends clinicians provide behavioral interventions, such as education or brief counseling.  

MedicalResearch.com Interview with: [caption id="attachment_51463" align="alignleft" width="165"]Hongying (Daisy) Dai, PhD Associate Professor Department of Biostatistics | College of Public Health University of Nebraska Medical Center Omaha Dr. Hongying (Daisy) Dai[/caption] Hongying (Daisy) Dai, PhD Associate Professor Department of Biostatistics | College of Public Health University of Nebraska Medical Center Omaha, NE MedicalResearch.com: What is the background for this study? Response: E-cigarette use increased dramatically from 11.7% to 27.5% for high school students and from 3.3% to 10.5% for middle school students during the periods of 2017 - 2019. In September 2018, the Food and Drug Administration (FDA) warned that youth e-cigarette use is reaching an epidemic proportion. Exposure to secondhand aerosol (SHA) from e-cigarettes is not harmless as e-cigarettes aerosol contains nicotine and potentially harmful substances, including carbonyl compounds, TSNAs, heavy metals, and glycols. This study analyzed the 2015-2018 National Youth Tobacco Survey (NYTS) and the main findings are:
  • The prevalence of secondhand aerosol exposure significantly increased from 25.6% in 2017 to 33.2% in 2018 (p<.001) after being stable during 2015 and 2017 (25.2% vs. 25.6%, p>0.05). The increase of SHA exposure from 2017 to 2018 was observed across socio-demographic groups.
  • Among never tobacco users in 2018 NYTS, students who reported secondhand aerosol exposure (vs. no) had higher odds of susceptibility to use e-cigarettes (38.8% vs. 21.0%) and cigarettes (30.7% vs. 21.2%) and higher odds of reporting exposure to e-cigarette marketing.

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. 

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.
