This study examined methamphetamine (MA) initiation patterns in 352 users, finding the average age of first use was 19. Early initiation was linked to non-African American ethnicity and sensation-seeking behaviors.

Area of Science:

  • Addiction Research
  • Adolescent Substance Use
  • Drug Policy

Background:

  • Limited data exists on methamphetamine (MA) initiation patterns among adolescent and adult users.
  • Understanding the sequence of drug use is crucial for effective prevention and intervention strategies.

Purpose of the Study:

  • To describe substance initiation patterns for 352 methamphetamine (MA) users.
  • To identify predictors of age of MA initiation and its sequencing within the broader context of substance use.

Main Methods:

  • Random sampling of 352 MA users from treatment admissions in a large California county.
  • Utilized an extensive natural history protocol for detailed interviews.
  • Collected data on age of initiation, sequence of drug use, and reasons for initiation.

Main Results:

  • The average age of MA initiation was 19 years.
  • Most participants (95%) initiated alcohol, marijuana, and tobacco use by age 13.
  • Earlier MA initiation was associated with being non-African American, earlier first substance use, criminal behavior, and sensation-seeking.
  • Later MA initiation was linked to being African American and using MA as a substitute for other drugs.

Conclusions:

  • Findings highlight diverse pathways to MA initiation, with significant variations in age and sequence.
  • Results can inform targeted prevention programs and the development of tailored interventions for MA users.
  • Understanding the role of ethnicity and reasons for use is critical for public health strategies.
