Background: Delta-8 THC is a federally unregulated psychoactive cannabis product rising in popularity. However, little is known regarding its retail availability. Method: We assessed Delta-8 THC retail by calling locations with alcohol, tobacco, and/or consumable hemp retail licenses in Fort Worth, Texas, before and after Texas announced ongoing litigation surrounding Delta-8 THC legality. We linked census block area deprivation index (ADI) scores (1-10; 10 = most disadvantaged) to locations. Logistic regression models examined associations between license type, ADI, ADI*license type interaction, and Delta-8 availability at each time. Results: Retail availability was 11% at Time 1 ( n  = 133/1,223) and 9% at Time 2 ( n  = 94/1,026). Alcohol (aOR Time1 = 0.18, 95%CI = 0.12,0.28; aOR Time2 = 0.14, 95%CI = 0.08,0.24), tobacco (aOR Time1 = 15.13, 95%CI = 6.78,33.74; aOR Time2 = 12.39, 95%CI = 4.97,30.91), and consumable hemp licenses (aOR Time1 = 21.85, 95%CI = 7.91,60.39; aOR Time2 = 22.93, 95%CI = 6.92,75.98) were associated with Delta-8 THC retail availability; ADI scores were borderline but not statistically significant. The multiplicative interaction at Time 2 indicated locations with both high ADI scores and alcohol retail licenses had higher odds of selling Delta-8 THC. Differential associations between ADI and Delta-8 THC availability were observed based on those with ( b  = 0.007) or without ( b = -0.023) alcohol retail licenses. Conclusions: Both timepoints had similar proportions of Delta-8 THC retailers, indicating that despite the uncertain legal landscape in Texas, interest in Delta-8 did not appear to be declining. Geographic socioeconomic disparities were observed among locations with alcohol retail licenses. Future regulations may include minimum distances from specific locations (e.g., schools), particularly in more disadvantaged areas. Increasing the compliance of Texas Delta-8 THC retailers to have the required hemp license is important for surveillance and product safety.

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.

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.
