What Is the Drug Use Disorders Identification Test (DUDIT)?

The Drug Use Disorders Identification Test (DUDIT) is a screening instrument for identifying individuals who may have risky drug habits, are heavily dependent on drugs, or do not have drug-related problems. It was composed as a corresponding tool to the Alcohol Use Disorders Identification Test (AUDIT) for the first-stage assessment of drug-related problems.

The DUDIT contains 11 questions which address issues such as:

The frequency of drug use per week/month
Polydrug use (combining drugs at the same time)
The frequency of drug use per day
Heavy use of a drug or drugs
Craving (strong urge to continue substance abuse)
Loss of control (inability to stop once started)
Prioritization of drug use over other duties
The need to take a drug the morning after heavy use ("Eye-opener")
Guilt feelings over drug use
Harmful use (physically or mentally hurting others)
Concern from others

You can use the DUDIT calculator whether you're a medical professional or a layperson with concerns about drug-related habits.

How Does the DUDIT Calculator Work?

Answer questions about drug use as correctly and honestly as possible. The drugs the instrument accounts for include:

Cannabis
Amphetamines
Opiates
Hallucinogens
Solvents/inhalants
GHB and others (anabolic steroids, laughing gas, amyl nitrate)
Sedatives/sleeping pills
Painkillers

⚠️ Note: If you take pills in the recommended dosage prescribed by a medical professional, they do not count as drugs in this context. Pills only count as drugs if you consume a higher dosage than prescribed, consume them to achieve euphoria, consume pills given by an acquaintance, or consume pills purchased on a "black market" or stolen.

FAQs

How do I score the DUDIT?

Score questions 1–9 on a 0–4 scale, questions 10–11 as 0, 2, or 4, then sum all points. Maximum score is 44.

Am I addicted to drugs if I scored 26?

If you scored 25 or more, there is a high probability that you may be dependent on one or more drugs. Consider seeking professional support.

Can the DUDIT screen for harmful alcohol use?

No. The DUDIT does not screen for harmful alcohol use. If you are worried about alcohol consumption, consider using the AUDIT, the CAGE questionnaire, or the SADS-Q.

What is the difference between AUDIT and DUDIT?

AUDIT identifies harmful alcohol consumption patterns. DUDIT identifies individuals with unhealthy drug-related behaviors. They are complementary screening instruments.
