Methamphetamine and cocaine users: differences in characteristics and treatment retention

Area of Science:

• Public Health
• Psychiatry
• Substance Abuse Research

Background:

• Methamphetamine and cocaine use present significant public health challenges.
• These psychostimulants share acute and chronic effects but differ in user demographics and outcomes.

Purpose of the Study:

• To compare patterns of use and consequences between cocaine and methamphetamine users.
• To assess treatment response in distinct stimulant-using populations.

Main Methods:

• Analysis of two large cohorts of treatment-seeking cocaine and methamphetamine users.
• Data collected from a single facility over a four-year period.

Main Results:

• Cocaine users exhibited more episodic use, higher spending, and greater alcohol consumption.
• Methamphetamine users had more daily use, higher marijuana co-use, a greater proportion of women, and more severe medical/psychiatric issues.
• Despite differences, both groups showed similar treatment responses to a multicomponent outpatient program.

Conclusions:

• Distinct patterns and consequences exist between cocaine and methamphetamine users.
• Outpatient, multicomponent treatment is effective for both populations, irrespective of drug of choice.
