Kratom use is associated with cannabis use, so retail availability may also be related. Kratom and Delta-8 THC (a psychoactive cannabis product) are federally unregulated, marketed as "natural," and often used for pain relief and/or relaxation. Kratom may have greater retail availability in more socioeconomically deprived areas because harmful substances are frequently marketed to lower-income communities. This study examined kratom retail availability in Fort Worth, Texas. Locations with alcohol, tobacco, and/or CBD licenses were called in July 2022: 1,025/1,223 (84%) answered the phone. T-tests examined potential differences in socioeconomic deprivation scores surrounding outlets by whether they sold kratom. Cross-tabulations examined overlap in kratom and Delta-8 THC availability. Kratom was available in 6% of locations. Most kratom retailers had a tobacco license (92%). However, most stores with a tobacco license did not sell kratom (14%), whereas most stores with a CBD license did (55%). Kratom availability was not associated with area deprivation scores. Most kratom retailers (95%) sold Delta-8 THC and two-thirds (65%) of Delta-8 THC retailers sold kratom. This study was the first to examine retail availability of kratom. Findings indicate the presence of niche stores specializing in the retail of federally unregulated substances. [ABSTRACT FROM AUTHOR]

Background: Simultaneous alcohol and cannabis (SAC) use is associated with more negative consequences than independent use of alcohol or cannabis. Contextual characteristics of drinking episodes are associated with the quantity of alcohol consumed and related risk. This study examined whether drinking contexts may also be associated with SAC use., Methods: National Survey on Drug Use and Health (NSDUH) 2010-2019 data from past 30-day drinkers aged 12-20 (n = 39,456) were used. A weighted multivariable logistic regression model examined associations between contextual characteristics (alcohol source, number of people, drinking location) and SAC use during their most recent drinking occasion. Models adjusted for survey year, heavy episodic drinking, age, sex, race/ethnicity, student status, and metropolitan area status., Results: More than one-in-five drinkers reported SAC use. Compared to getting alcohol from parents/family, those who took it from a home (OR = 1.51,95 %CI = 1.24,1.84), got it for free another way (OR = 2.30,95 %CI = 2.05,2.59), paid someone else for it (OR = 2.83,95 %CI = 2.46,3.25), or purchased it themselves (OR = 3.12,95 %CI = 2.66,3.67) had higher odds of SAC use. Compared to drinking alone, drinking with more than one person was associated with higher odds of SAC use (OR = 1.36,95 %CI = 1.12,1.66). Compared to drinking in their home, drinking in a bar (OR = 0.51,95 %CI = 0.41,0.64) had lower odds of SAC use, whereas drinking in someone else's home (OR = 1.12,95 %CI = 1.02,1.22), a car (OR = 1.36,95 %CI = 1.04,1.77), or multiple locations (OR = 1.29,95 %CI = 1.09,1.53) had higher odds of SAC use., Conclusions: Findings suggest that alcohol-related contextual characteristics are associated with SAC use among underage drinkers. Laws addressing underage alcohol consumption, including social host liability and sales to minors laws, may also decrease simultaneous cannabis use., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

Human papillomavirus (HPV) is a common sexually transmitted infection. Binge drinkers often engage in HIV/HPV co-infection high-risk behaviors. We examined the association between binge drinking, HIV/HPV co-infection risk, HIV testing and HPV vaccination among young adults. Data from the 2017 Behavioral Risk Factor Surveillance System survey were examined. Participants (N = 430/450,016; 0.11%) were HPV vaccine-eligible young adults ages 18-26 years. Multivariable logistic regression examined the association between binge drinking in the past 30 days, HIV/HPV co-infection high-risk risk behaviors, HIV testing, and HPV vaccination (initiated/completed, unvaccinated) among young adults. Respondents were primarily cisgender (99.8%), non-Hispanic White (41.4%), employed (46.2%) or student (35.4%), and insured (68.2%). Most did not binge drink (55.2%). The majority did not engage in HIV/HPV co-infection high-risk risk behaviors (78.2%). More than one-half had never been tested for HIV (59%) nor vaccinated against HPV (60.6%). Although binge drinkers (44.8%) were significantly more likely to engage in HIV/HPV co-infection high-risk behaviors (OR = 2.1; 95% CI: 1.0-4.5), binge drinking was not positively associated with HIV testing (OR = 0.98; 95% CI: 0.63-1.53). After adjusting for demographics and HIV/HPV co-infection high-risk behaviors, one (aOR = 2.71; 95% CI: 1.11-6.65) and two episodes (aOR = 3.05; 95% CI: 1.26-7.41) of binge drinking in the past 30 days were significantly associated with HPV vaccination uptake. Positive associations between HPV vaccination and participants having an HIV test in 2017 (aOR = 3.86; 95% CI: 1.42-10.55) and before 2017 (aOR = 2.62; 95% CI: 1.23-5.56) were also statistically significant. Because young adult binge drinkers are more likely to engage in HIV/HPV co-infection high-risk behaviors, promoting HPV vaccination and HIV testing are important public health objectives., Competing Interests: Declaration of competing interest The authors declare that there are no conflicts of interests., (Copyright © 2020 Elsevier Inc.
