Methamphetamine use among gay, bisexual and non-identified men-who-have-sex-with-men: an analysis of daily patterns.

This study sought to understand the patterns, methods of administration and contexts for methamphetamine use (MA) in a sample of racially diverse men who have sex with men (MSM). Inclusion into the study required participants to be classified as clinically dependent on MA, but indicate no other illicit substance use. Use was assessed using Timeline Followback for a period of 30 days.
