Aims: Investigate changes to a prospective cohort of methamphetamine users over 12 months, predictors of remission from methamphetamine dependence and past-month abstinence from methamphetamine use.
Method: Structured interviews were administered to 255 regular methamphetamine users at baseline (2010) and 12 months (2011). A multivariate generalised estimating equation (GEE) model identified adjusted associations with past-month abstinence at follow-up. A multivariate logistic regression analysis identified factors independently associated with remission from methamphetamine dependence.
Results: Most (60%) participants were methamphetamine-dependent at baseline. Remission from dependence (n = 38) was independently associated with age (OR: 0.93; 95% CI: 0.88–1.00), maintaining/gaining employment since baseline (OR: 3.14; 95% CI: 1.21–8.14) and a greater increase in self-perceived social support (OR: 1.08; 95% CI: 1.01–1.16). Past-month abstinence at follow-up was independently associated with being female (OR: 1.94; 95% CI: 1.10–3.44), recent criminal behaviours (OR: 0.46; 95% CI: 0.26–0.82), recent ecstasy (OR: 0.30; 95% CI: 0.12–0.72) and benzodiazepine use (OR: 0.53; 95% CI: 0.29–0.96), and being less methamphetamine-dependent (OR: 0.79; 95% CI: 0.72–0.88). Drug treatment was not independently associated with either outcome at follow-up.
Conclusions: Our findings highlight the potential for natural remission from methamphetamine dependence; however, targeted interventions should be developed for individuals who are likely to maintain dependent/harmful use patterns.

- VMAX: Understanding meth use in Victoria
To help us better understand what is happening in the community with meth use, Burnet is undertaking this study of 800 people who use meth n Melbourne and regional Victoria.
