Prospective associations of e-cigarette use with cigarette, alcohol, marijuana, and nonmedical prescription drug use among US adolescents.
As e-cigarette use continues to increase in the U.S., research is needed to understand its prospective risk for cigarette smoking and other substance use in young adulthood, including alcohol, marijuana, and nonmedical prescription drugs (NMPDs). ⋯ This study suggests that e-cigarette use may be an indicator of future substance use risk in young adulthood. Adolescent e-cigarette users may benefit from secondary prevention efforts to mitigate this risk.

Young adult e-cigarette use: A latent class analysis of device and flavor use, 2018-2019.
The myriad of e-cigarette devices and flavors used by young adults (YAs) complicates identification of the particular e-cigarette products that are associated with more frequent tobacco use and merit consideration for regulation. The current study used latent class analysis to identify distinct patterns of e-cigarette device and flavor use and evaluate their association with vaping and smoking frequency. ⋯ Although YAs that predominately used pod devices alongside non-tobacco flavors were most common, YAs characterized by a proclivity toward using many different devices and flavors were appreciably prevalent and smoked and vaped more frequently. Regulations targeting a wide spectrum of vaping products may be optimal in protecting YA health.

Evaluating the impact of COVID-19: A cohort comparison study of drug use and risky sexual behavior among sexual minority men in the U.S.A.
Sexual minority men who use drugs have high sexual HIV transmission risk. Sexual interactions may also increase COVID-19 risk.This study compared marijuana use, other illegal drugs use (i.e. cocaine/crack, methamphetamine, MDMA/ecstasy, GHB, and ketamine) and sexual behavior with casual partners among sexual minority cismen active on social networking and dating applications before and during the COVID-19 epidemic. ⋯ While the proportion of participants reporting drug use and condomless anal sex with casual partners declined in the COVID cohort, the association between drug use and sexual behavior was magnified. Sexual minority men who use drugs are significantly more likely to engage in sexual behaviors that place them at risk for HIV and COVID-19 transmission.

Assessing how the history of e-cigarette and cigarette use are associated with the developmental course of marijuana use in a sample of United States adolescents.
The purpose of this study was to determine the developmental course of marijuana use among adolescents based on their history of cigarette and e-cigarette use among a national U.S. sample of adolescents who were followed over a four year time-period. ⋯ While concurrent and non-concurrent dual use was strongly associated with marijuana use over the study period, marijuana use increased at a faster rate across the four-year span of the study among e-cigarette only users.

Trajectories of cannabis use and risk for opioid misuse in a young adult urban cohort.
Although much of the attention surrounding the opioid epidemic has focused on rural and suburban Whites and prescription opioids, heroin overdoses among urban Blacks are on the rise. While some argue that legalization of cannabis will combat the epidemic, there are concerns it ignores the shift in the epidemic and could increase vulnerability to opioid misuse. The goal of this study is to examine the association between cannabis use from adolescence to young adulthood with opioid misuse in a primarily urban Black cohort. ⋯ Adolescent onset cannabis use is associated with opioid misuse in young adulthood among urban Blacks even after adjustment for socioecological factors associated with opioid misuse.
