8 % during the study period. There was a statistically significant interaction between traumatic injury death and AOD on both an additive scale and multiplicative scale. (Odds Ratio for interaction term = 1.76, 95 % CI = 1.53, 2.03).
 
  AOD use does not provide a protective benefit in the setting of trauma, but rather is an important contributor to traumatic injury mortality.

  Both marijuana and other illicit drugs (e.g., cocaine/crack, methamphetamines, ecstasy, gamma-hydroxybuterate, and ketamine) have been linked to the occurrence of condomless anal sex (CAS) with casual partners among sexual minority men (SMM) and these associations largely generalize to partnered SMM. Software advances now permit testing the day-level correspondence between participants' sexual behavior and their own drug use (actor effects) as well as their partners' (partner-effects).
 
  Participants comprised 50 couples (100 individuals) recruited in the New York City metro area. All were 18 or older and identified as cis male. In each couple, at least one partner was 18-29 years old, HIV-negative, reported recent (past 30 day) drug use and recent (past 30 day) CAS with a casual partner or CAS with a non-monogamous or sero-discordant main partner at screening.
 
  Marijuana was associated with CAS between main partners on days both partners reported its use. A similar pattern was observed for other illicit drugs. Respondents were more likely to report CAS with casual partners on days CAS between main partners occurred. Both marijuana and other illicit drugs were associated with increased likelihood of CAS with casual partners on days a main partner did not use drugs. These associations were attenuated on days where partners reported the use of different drugs.
 
  The co-occurrence of CAS with main and casual partners maximizes shared sexual risk. Results support the continued emphasis on dyadic HIV prevention interventions and the development of theoretically-based interventions that may address drug use by both partners in the relationship.

  Alcohol and cannabis co-users experience more negative alcohol consequences, but distal and mediating mechanisms of this association remain largely unstudied. Considering research suggests that individuals high in impulsivity and sensation seeking are more likely to be co-users, it is possible that co-users have more positive expectancies and become heavier drinkers, which confer risk for future negative consequences. Therefore, the current study tested prospective mediation models in which impulsive personality traits indirectly predicted negative consequences through co-use, heavier drinking, and expectancies.
 
  The current study used data from a study of familial AUD spanning 3 waves (1995-2010). Participants (N = 567) reported on impulsivity (via the Eysenck Personality Inventory and Sensation Seeking Scale) alcohol and cannabis use, alcohol expectancies, and negative consequences. Models tested the factor structure of impulsive personality traits and whether these traits predicted future negative consened variance in future negative alcohol consequences via heavier drinking (behavior) and positive expectancies (cognition). Personalized interventions targeting a lack of premeditation, and sensation seeking in co-users, may interrupt a developmental trajectory toward problem drinking.
  Alcohol policies reduce population-level binge drinking; however, they may not reduce binge drinking disparities between different populations. We examined the association between the alcohol policy environment and binge drinking among Lesbian, Gay and Bisexual (LGB) and heterosexual adults in the presence and absence of state laws protecting LGB people from discrimination.
 
  The 2015-2018 Behavioral Risk Factor Surveillance System (BRFSS) provided information about individual-level binge drinking, sexual identity, and individual-level covariates. The Alcohol Policy Scale (APS) score measures the strength of the alcohol policy environment. Presence of state-level nondiscrimination protections based on sexual orientation came from the Movement Advancement Project.  https://www.selleckchem.com/products/alkbh5-inhibitor-2.html  Logistic regression models were used to test whether nondiscrimination statutes modified the association between the alcohol policy environment and binge drinking and whether this interaction differed for LGB and heterosexual adults.

  Emerging literature shows increased drug use during the COVID-19 pandemic. However, limited research has examined the change in marijuana use among persons living with HIV (PLWH). This study aimed to investigate how marijuana use changed in a cohort of PLWH during the first year of the pandemic and identify factors associated with the change.
 
  222 PLWH (mean age = 50.2 ± 11.2, 50.9 % female, 14.5 % Hispanic, 64.7 % Black, 15.8 % White, 5 % other, 80.2 % persons using marijuana [at least weekly use], 19.8 % persons not using marijuana) completed a baseline survey on demographics and behavioral/health characteristics between 2018 and 2020 and a brief phone survey between May and October 2020 that assessed changes in marijuana use and overall/mental health, and perceived risks/benefits of marijuana use during the COVID-19 pandemic.
 
  During the pandemic, 64/222(28.8 %) of the whole sample reported increased marijuana use, 36(16.2 %) reported decreased use, and 122(55 %) reported no change. Multinomial logistic regression results indicated that Compared to those reporting no change, increased marijuana use during the pandemic was associated with more frequent marijuana use and PTSD symptoms at baseline, worsened mental health during the pandemic, and not perceiving marijuana use as a risk factor for COVID-19 infection. More frequent marijuana use at baseline was the only factor significantly associated with decreased marijuana use during the pandemic.
 
  The COVID-19 pandemic has resulted in changes in marijuana use among a considerable proportion (45 %) of PLWH. Future research is needed to understand the temporality of the increases in marijuana use with worsening mental health.
