Drinking among young adult users of amphetamine-type stimulants (ATS) during episodes of ecstasy and methamphetamine use is reported to have a number of possible functions, such as mitigating the unwanted effects of the drugs, enhancing intoxication and pleasure, and increasing drinking capacity. While there is evidence to suggest a high prevalence of risky drinking among users of ATS in Australia, little is known about how they combine their use of ATS with the consumption of alcohol or why they do so. This paper considers how ATS users consume alcohol during ecstasy and methamphetamine use, and also addresses alcohol abuse and dependence among low-risk and at-risk ATS users.

At-risk users are more likely to have experienced alcohol abuse and dependence during adolescence or early adulthood, suggesting that higher-risk use of ATS may be linked with problematic drinking patterns. The paper suggests that problematic behaviour relating to alcohol and ATS use is interlinked, and may be important in developing appropriate policy responses.
