Identification with drug use among young adults who are at risk of transitioning to more serious use.

Understanding the drug use trajectories for at risk young adults can help reduce harms associated with serious drug use. This longitudinal study tracked young people to assess whether implicit and explicit identification with substance use predicts changes in use over time and whether patterns of use impacts identification with drugs. Two hundred and twenty-eight participants were initially recruited from homeless shelters, youth centers, drug health services, and parks where young people who use drugs are known to frequent. Over a 20-month period, 78 of these original participants were successfully recontacted and surveyed again. The survey assessed implicit and explicit identification with drug use, along with known risk factors, to determine if identification predicts changes in drug use over time as assessed by frequency, recency, and multiple drug use. Results revealed that implicit and explicit identification with drug use were stronger among participants who used more frequently, more recently, and used multiple drugs, although this finding only emerged cross-sectionally and not longitudinally. Overall, these results suggest that patterns of drug use are associated with the identity of the individual and that identification with drug use is a marker of drug-using behavior, but identification with drug use does not appear to be predictive of future behavior nor an outcome of prior drug use.
