ABSTRACT
PURPOSE: No studies of young adults have compared symptoms of nicotine dependence among exclusive past 30-day (P30D) ENDS users versus exclusive P30D cigarette smokers. METHODS: Participants at Wave 14 (Fall 2021) of The Texas Adolescent and Tobacco Marketing Surveillance System (TATAMS) (n = 2,341; mean age = 20.95 years old) who reported P30D exclusive ENDS use (n = 212) and P30D exclusive cigarette smoking (n = 46). Symptoms of nicotine dependence were measured with the Hooked On Nicotine Checklist (the 10-item HONC scale). An independent samples t-test compared average HONC scores between groups, and a Pearson (or Fisher's Exact) Chi-Square (X2) test compared the prevalence of symptom(s) between groups. RESULTS: The average HONC score was significantly higher for exclusive P30D ENDS users than exclusive P30D cigarette smokers (3.51 vs. 1.91, p ≤ 0.001). Compared to exclusive P30D cigarette smokers, a significantly higher proportion of exclusive P30D ENDS users reported having felt addicted (45.28% vs. 15.22%, p ≤ 0.001), having strong cravings (50.00% vs. 28.26%, p = 0.007), difficulty not using in prohibited places (i.e., school or work) (24.06% vs. 4.35%, p = 0.002), difficulty concentrating (21.23% vs. 6.52%, p = 0.021), and feeling nervous, restless, or anxious (28.77% vs. 10.87%, p = 0.012). CONCLUSIONS: Symptoms of nicotine dependence were elevated among young adults who were exclusive P30D users of ENDS relative to exclusive P30D cigarette smokers.

Background: With the widespread legalization of cannabis and use among all age groups, location and source of cannabis remains to be researched, especially among minority populations. Methods: We pooled data from the 2018-2019 National Survey on Drug Use and Health and investigated differences by sexual minority status of where individuals obtained cannabis. Results: Results found that gay/lesbian and bisexual individuals who reported use were more likely to get marijuana from buying it, trading it for something else and getting it for free or sharing someone else's, compared to heterosexual individuals. Furthermore, more than one in five lesbian/gay individuals reported obtaining marijuana from someone they just met while nearly 25% of bisexual women reported obtaining marijuana from a friend. Conclusions: Findings from the present study may inform harm reduction and policy initiatives.
