Most research regarding sexual and gender minority (SGM) populations is limited to examination of cigarette or general tobacco use or does not examine heterogeneity across SGM groups other than lesbian or gay and bisexual individuals. This study examined differences in the odds of current use and age of initiation of five tobacco/nicotine products among three groups of SGM young adults who self-identified as (1) gay or lesbian, (2) bisexual, and (3) queer, transgender, or "other," compared to their heterosexual peers. ⋯ This study extends the current literature by including the sexual and gender minority identity options of queer, transgender, and "other," highlighting disparities in tobacco use between young adults in these subgroups compared to their heterosexual peers, particularly in noncigarette tobacco product use. Findings underscore the need for the Food and Drug Association and other health agencies to tailor health communication efforts specific to sexual and gender minority populations pertaining to the risks and harms surrounding tobacco product use.

Among United States teens during the 1990s, increasing cigar use coincided with increasing use of tobacco cigar shells filled with cannabis, called "blunts." Cigar smokers are more likely to use cannabis, and we hypothesized that starting to smoke cigars might be a probabilistic "trigger" of blunt smoking. We turned to the case-crossover approach to evaluate this hypothesis. ⋯ If this evidence is correct, increased market-targeting to promote youthful cigar and cigarillo smoking might be followed by increased rates of blunt smoking in a vulnerable population. As noted by others, enhanced risk of smoking-attributable harms might be a consequence of mixed tobacco-cannabis formulations.

A Proactive Smoking Cessation Intervention for Socioeconomically Disadvantaged Smokers: The Role of Smoking-Related Stigma.
Smoking denormalization has been paralleled by reduced smoking prevalence, but smoking rates among socioeconomically disadvantaged populations remain high. The social unacceptability of smoking has also led to increased perceptions of smoking-related stigma. By examining how smoking stigma influences cessation intervention effectiveness, we can better tailor interventions to socioeconomically disadvantaged smokers. ⋯ Smoking denormalization has led to increased perceptions of smoking-related stigma among many smokers; however, little is known about how this stigma influences the cessation process. In the present study, smokers with lower levels of perceived smoking-related stigma lived in social environments that were more conducive to smoking and were less motivated to quit than higher stigma smokers. Despite these barriers, our proactive outreach cessation intervention was more effective for lower stigma smokers, suggesting that interventions which utilize proactive outreach to stimulate interest in quitting and offer facilitated access to free cessation treatments are an effective treatment approach for these hard-to-reach smokers. These strategies may be particularly effective for motivating smokers enrolled in government-subsidized health insurance programs to take advantage of cessation resources.

Lesbian, gay, bisexual, or queer/questioning (LGBQ) microaggressions refer to often-unintentional insults, assaults, and invalidations that denigrate sexual minorities. While experiencing hostile discrimination and violence has previously been associated with elevated rates of smoking cigarettes for LGBQ college students, the relationship between LGBQ microaggressions and smoking is unknown. ⋯ Microaggressions related to sexual minority identity include subtle forms of discrimination experienced during daily interactions that can create hostile and stressful social environments for a socially disadvantaged group. Prior research has demonstrated that LGBQ college students have higher rates of cigarette smoking, and that experiencing identity-based violence is a risk factor. This study revealed that experiencing frequent LGBQ microaggressions on college campus is associated with increased likelihood of current smoking among LGBQ college students.

Modified-risk tobacco products are expected to reduce exposure to harmful and potentially harmful constituents of cigarette smoke, and ultimately reduce the health burden of smoking-related diseases. Clinically relevant risk markers of smoking-related diseases inform about the risk profile of new tobacco products in the absence of in-market epidemiological data. The menthol Tobacco Heating System 2.2 (mTHS) is a modified-risk tobacco product in development as an alternative to cigarettes (conventional cigarettes [CCs]). ⋯ In this three-way randomized study, switching from menthol cigarettes to mTHS for 5 days in confinement and 85 days in ambulatory settings was associated with reductions in biomarkers of exposure to cigarette smoke, and changes were observed in clinically relevant biomarkers of oxidative stress (8-epi-prostaglandin F2α), platelet activity (11-dehydro-thromboxane B2), endothelial function (soluble intracellular adhesion molecule-1), lipid metabolism (high-density lipoprotein cholesterol) and lung function (forced expiratory volume in 1 second), similar to the SA group. The results suggest that switching to the mTHS has the potential to reduce the adverse health effects of conventional cigarettes.
