title: Methamphetamine and cocaine users: differences in characteristics and treatment retention.
abstract: The use of methamphetamine and cocaine have both produced significant public health problems during the past two decades. Although these powerful psychostimulants have many common acute and chronic effects, there are some important differences in who uses these drugs and the consequences of their use. This article reports on two large cohorts of treatment-seeking cocaine and methamphetamine users who entered treatment at the same facility over the same four-year period of time. Patterns of use differed significantly. Cocaine users have more episodic use patterns, spend more money on purchasing their drugs, and use alcohol more heavily. Methamphetamine users include a higher proportion of women, more frequently use on a daily basis, use marijuana more often, and experience more severe medical and psychiatric consequences. Despite the differences in the stimulant drug effects and consequences, the treatment response to a multicomponent, outpatient program is very similar.
