Insomnia and parasomnia induced by validated smoking cessation pharmacotherapies and electronic cigarettes: a network meta-analysis

We aim to assess the relationship between validated smoking cessation pharmacotherapies and electronic cigarettes (e-cigarettes) and insomnia and parasomnia using a systematic review and a network meta-analysis. A systematic search was performed until August 2022 in the following databases: PUBMED, COCHRANE, CLINICALTRIAL. Randomized controlled studies against placebo or validated therapeutic smoking cessation methods and e-cigarettes in adult smokers without unstable or psychiatric comorbidity were included. The primary outcome was the presence of "insomnia" and "parasomnia." A total of 1261 studies were selected. Thirty-seven studies were included in the quantitative analysis (34 for insomnia and 23 for parasomnia). The reported interventions were varenicline (23 studies), nicotine replacement therapy (NRT, 10 studies), bupropion (15 studies). No studies on e-cigarettes were included. Bayesian analyses found that insomnia and parasomnia are more frequent with smoking cessation therapies than placebo except for bupropion. Insomnia was less frequent with nicotine substitutes but more frequent with bupropion than the over pharmacotherapies. Parasomnia are less frequent with bupropion but more frequent with varenicline than the over pharmacotherapies. Validated smoking cessation pharmacotherapies can induce sleep disturbances with different degrees of frequency. Our network meta-analysis shows a more favorable profile of nicotine substitutes for insomnia and bupropion for parasomnia. It seems essential to systematize the assessment of sleep disturbances in the initiation of smoking cessation treatment. This could help professionals to personalize the choice of treatment according to sleep parameters of each patient. Considering co-addictions, broadening the populations studied and standardizing the measurement are additional avenues for future research.

"Isn't there a bunch of side effects?": A focus group study on the beliefs about cessation treatments of non-college educated young adult smokers

Smoking remains more prevalent among non-college educated and racial/ethnic minority young adults in the U.S. These smokers are less likely than their college educated/non-Hispanic white counterparts to use cessation treatments approved by the U.S. Food and Drug Administration (FDA). Alternative cessation methods (e.g., e-cigarettes) have also grown in popularity among smokers. Therefore, we conducted a focus group study to explore perceptions and beliefs about various cessation treatments among, racially/ethnically diverse, non-college educated young adult smokers. Seventy-five 18-29-year-old current smokers without a 4-year college education were recruited from the U.S. Washington, D.C. metropolitan area and attended one of twelve focus groups to discuss their awareness, beliefs, experiences, and intention for future use of cessation treatments. Focus groups were stratified by race/ethnicity (non-Hispanic white, non-Hispanic black, and Hispanic) and educational attainment (≤ high school vs. some college without obtaining a bachelor's degree). We used a thematic approach to analyze the discussions. We found that few participants were aware of cessation counseling or cessation related programs. Many participants reported previously using nicotine replacement therapies and e-cigarettes to quit smoking. Participants had little intention to use prescription medications due to perceived side effects. Participants' awareness, beliefs, and intentions of using other cessation treatments varied by race/ethnicity and educational attainment. In conclusion, our findings, if confirmed by subsequent quantitative studies, suggest that targeted media campaigns may be needed to explain the contents and benefits of behavioral cessation programs to non-college educated young adult smokers. Targeted media messages aim to overcome negative perceptions related to nicotine replacement therapy and prescription medications among non-college educated young adult smokers, especially those from racial/ethnic minority populations, may promote successful smoking cessation in this population.
