Marijuana is the most prevalent drug in the U.S. Approximately 70% of the 2.8 million individuals who initiated use of illicit drugs in 2013 reported that marijuana was their first drug. Despite extensive research examining potential links between marijuana use and other drug use, the literature is currently lacking data regarding which illicit marijuana users are most likely to engage in use of other illicit drugs.
A new study, published in the American Journal of Drug and Alcohol Abuse by researchers affiliated with New York University's Center for Drug Use and HIV Research (CDUHR), examines how reasons for illicit marijuana use relates to the use of other drugs individually, rather than grouping them into a single "illicit drug" group.
"Aside from marijuana, a wide range of illicit drugs are prevalent, each having different use patterns, and different effects and dangers associated with use," said Joseph J. Palamar, PhD, MPH, a CDUHR affiliated researcher and an assistant professor of Population Health at NYU Langone Medical Center (NYULMC). "Our research helped to identify subtypes of illicit marijuana users who use other drugs, as this may be able to inform prevention efforts."
