1.	Normalising Desistance: Contextualising Marijuana and Cocaine Use Careers in Young Adults Sociology of Health and Illness 38,6 (July 2016): 916-938.

Although there is a vast literature on drug use and addiction, there is little work that addresses the long-term use of drugs within the general population. We take a more contextual look in examining longitudinal drug use patterns over the course of 14 years for a representative sample of young adults in their late teens and early twenties in the United States using the National Longitudinal Survey of Youth (NLSY). We use a growth trajectory modelling approach for cocaine and marijuana users to determine general use careers. Using contextual and life-course variables, we then estimate a multinomial logistic regression model to predict group membership. In addition to establishing general use career groups, we ask how well mainstream theories comport with our findings and how the different chemical makeup of cocaine and marijuana influence our findings. We find four general use career groups: (i) high use/late desistance; (ii) peaked use/strong desistance; (iii) low use; and (iv) stable use/gradual desistance. Our results suggest similar careers for users of both drugs, with desistance over time as the rule for all groups. We also find some support for life-course and contextual factors in drug using patterns, but our findings challenge other psychological and criminological theories.

2.	Situating Drug Use Over the Lifecourse: Using Empirical Findings to Attempt to Build Theory Presented: Vancouver, BC, Western Society Of Criminology, 38th Annual Conference, February 3-5, 2011. Also: http://westerncriminology.org/documents/conference_proceedings/WSC_2011_Conference_Program.pdf Cohort(s): NLSY79 Publisher: Western Society of Criminology Keyword(s): Census of Population; Crime; Drug Use; Geographical Variation; Modeling, Growth Curve/Latent Trajectory Analysis Permission to reprint the abstract has not been received from the publisher. This project explores drug use over the life course with data from the 1979 National Longitudinal Survey of Youth. We examine dichotomous indicators for multiple drugs for a sample of youth, using growth trajectory models to describe trajectories over 5 time points (1984-2002). Using individual NLSY variables and county data from the US Census, we frame our analysis within a structural context. Though criminological theorizing about issues of drugs and addiction is scattered, we draw on two perspectives that consider within-individual drug use over time. Caspi and Moffitt's developmental approach emphasizes the relative stability of antisocial behavior over the life course, including drug abuse. Sampson and Laub's life course perspective, on the other hand, acknowledges the heterogeneity of offending over time in the form of "turning points" such as marriage. Based on our preliminary findings, we would like to explore alternative theoretical frameworks for understanding addiction sociologically and criminologically.
