NM ASSIST – FAQ

What is the NM ASSIST?

A NIDA tool adapted from WHO’s ASSIST to check involvement with illicit or nonmedical prescription drugs by substance, with risk bands for each.

Who should use it?

Adults after a positive NIDA Quick Screen for drugs. It’s a screen, not a diagnosis.

How is it scored?

For each substance, add scores on Q2–Q7 to get a Substance Involvement (SI) score. 0–3 lower, 4–26 moderate, 27+ high.

Do you include alcohol or tobacco here?

This version focuses on illicit and nonmedical prescription drugs. Alcohol and tobacco are covered in the NIDA Quick Screen and other dedicated tools.

Do you store my answers?

No. Answers stay in your browser using localStorage. The share link encodes results in the URL hash, so nothing is stored on our server.

What should I do with a moderate or high score?

Consider brief intervention and talking with a licensed clinician. Use our tools to support motivation and coping and see the Get Support page for services.
