Drug Abuse Screening Test

Psych Test Homepage

This Drug Abuse Screening Test (DAST-20) can help determine whether you might have a problem with the use or abuse of drugs. It is one of the two standard tests that doctors and counselors use to determine if an individual is an addict.

Use the results to help decide if you need to see a doctor or other mental health professional to further discuss diagnosis and treatment of drug addiction or drug abuse. (This test does NOT measure alcohol use.)


The following questions concern information about your involvement and abuse of drugs. Drug abuse refers to:

  1. the use of prescribed or "over the counter" drugs in excess of the directions
  2. any non-medical use of drugs

The questions DO NOT include alcoholic beverages. The DAST does not include alcohol use.

The questions refer to the past 12 months. Carefully read each statement and decide whether your answer is YES or NO. Please give the best answer or the answer that is right most of the time.
