Prevention of methamphetamine abuse: can existing evidence inform community prevention?

Little research exists on effective strategies to prevent methamphetamine production, distribution, sales, use, and harm. As a result, prevention practitioners (especially at the local level) have little guidance in selecting potentially effective strategies. This article presents a general causal model of methamphetamine use and harms that reflects the available findings from either research specific to methamphetamine or from alcohol and other illegal drugs, and suggests prevention approaches and strategies that communities might use based upon research evidence and experience. Community methamphetamine prevention can use the public health and safety perspective applied to other substance abuse prevention. Analyses of the complex system of intermediate variables that interact to affect methamphetamine use and harms suggest that multiple reinforcing prevention interventions may have the greatest potential effectiveness.
