Substance Use Inventory

This brief measure asks detailed questions regarding participants' use and administration route of a variety of substances in the previous seven days, including alcohol, cocaine, heroin, and marijuana, along with shorter sections about sedatives, PCP, stimulants, and hallucinogens. Respondents are asked how many times in the past seven days each substance was used and what the administration route was (smoked, oral, injected, e.g.), as well as the average dollar amount of each drug used each day and the maximum dollar value of each drug used in a single day. The scale ends with a few questions about craving and urges to use. This scale can be used for baseline and follow-up assessments, as well as for treatment phase assessments. Population: Adults
