Substance use self-check

The past 12 months. Separate nonmedical substance use from craving, control and daily impact. Taking treatment as prescribed is not itself treated as a problem.

This original self-check draws on research concepts; it is not a standardized test or diagnostic tool. Its questions, weights and minimum-answer rules are editorial choices without clinical validation. You may decline or choose not applicable, and interpretation depends on your circumstances and responses. Use experience alone does not establish dependence or addiction. We do not ask for substances, sources or use methods; do not stop or change prescribed treatment based only on this result.

Not applicable and declined answers are excluded from scores. Declining the experience question lets you finish without any inference about use.
