Abstract: This project used ecological momentary
assessment (cell phones and interactive voice response technology)
to examine the separate versus combined use of malt liquor (a cheap
high-alcohol beer) and marijuana among young adults (age 18 –
30 years) who regularly use both substances. These young adults may
be at high risk for substance dependence and other negative
consequences. Knowledge of a variety of episode-specific
antecedents and correlates of substance use will help to inform
efforts to prevent excessive use and to treat substance-related
