The DAST-10 is the drug-use counterpart to the AUDIT. Skinner published it in 1982 as the brief version of the original DAST-28, and CAMH has maintained it as a free-clinical-use instrument since. It covers drugs other than alcohol — prescription misuse, cannabis, stimulants, opioids, sedatives, hallucinogens — over the past 12 months.

​
What it measures

Drug-use problems and consequences across 10 yes/no items:
  • Loss of control (using more than intended, inability to stop)
  • Social and occupational consequences (family, work, legal)
  • Withdrawal and dependence symptoms
  • Treatment history
Item 3 is reverse-scored: “Are you always able to stop using drugs when you want to?” A “No” answer counts as 1 point; “Yes” counts as 0. Rivet’s template encodes this directly in the answer-option scoring, so the live-scoring pill is correct without any manual adjustment.

​
When to send it

  • Intake substance-use baseline alongside the AUDIT (alcohol) for a full picture
  • Treatment-response monitoring during substance-use work
  • SBIRT protocols where AUDIT alone is incomplete
  • When a CAGE-AID positive screen surfaces drug use specifically and you want the severity gradient
The 10 items take 2–3 minutes. Async administration works well — endorsement of drug use without a clinician present in the room is sometimes more candid.

How Rivet scores it

Sum of yes-scored items, range 0–10.
TotalBand
0No problems reported
1–2Low level
3–5Moderate level — further assessment indicated
6–8Substantial level
9–10Severe level
Cutoff ≥3 surfaces the “further drug-use assessment indicated” flag.

When not to use it

The DAST-10 is silent on alcohol — pair it with the AUDIT or AUDIT-C when alcohol is part of the picture. For adolescents (12–21), the CRAFFT is the validated alternative and covers alcohol and drugs in one form.
