Cannabis Use Disorder Test (CUDIT-R): See Your Hazardous Use Score
This cannabis use test reproduces the Cannabis Use Disorders Identification Test-Revised (CUDIT-R) exactly as published, the 8-item screener researchers and clinics use to flag hazardous cannabis use. Get an instant score and an optional PDF report.
Reviewed by Michael Callans, MSW 
Cannabis Use Disorder Test (CUDIT-R) is a free, confidential 8-question self-assessment, the 8 CUDIT-R items, verbatim. It takes about 6 minutes, runs entirely in your browser, and gives you a plain-language score across 3 interpretation bands plus an optional in-depth report. It is an educational screening, not a diagnosis.
A straightforward number, no judgment attached
The CUDIT-R was built to be quick, honest, and free of moralizing: 8 questions about how often you use cannabis, what it costs you, and how much control you have over it. This test reproduces those exact questions and the published scoring.
The full CUDIT-R, verbatim
All 8 items from the Cannabis Use Disorders Identification Test-Revised (Adamson et al., 2010), worded exactly as published, covering frequency, intensity, and consequences of cannabis use.
The published scoring, exactly
Items 1 through 7 are scored 0 to 4 and item 8 is scored 0, 2, or 4, the same point structure used in the original research, for a total from 0 to 32.
The validated cutoff, explained honestly
A score of 13 or higher correctly identified cannabis use disorder in a clinical sample, with about 91 percent sensitivity and 90 percent specificity. The widely repeated 8 and 12 figures are scoring-sheet guidance, not that validated number. We show you where you land against all of it.

How scoring works
Answers are scored 0–32 in total. Your result falls into one of 3 bands:
| Score | Band | What it suggests |
|---|---|---|
| 0–8 | Low-risk range | Your CUDIT-R score falls below every population cutoff used in the research, including the lowest one reported. Your current pattern of cannabis use does not show the signs this screener flags. |
| 9–12 | Elevated, population-dependent range | Your CUDIT-R score falls in a range that different studies treat as their own cutoff. Depending on who was studied, a score like yours has been flagged as hazardous or clinically significant. |
| 13–32 | Likely cannabis use disorder range | Your CUDIT-R score is at or above 13, the cutoff that correctly identified cannabis use disorder in a clinical sample with about 91 percent sensitivity and 90 percent specificity. |
Tolerance and Withdrawal, Explained Plainly
Tolerance means needing more cannabis over time to get the same effect, which happens because the body's cannabinoid receptors adapt to regular exposure. Withdrawal refers to the cluster of symptoms, irritability, sleep trouble, decreased appetite, restlessness, and low mood, that can show up within about a day of stopping after frequent, heavy use. Cannabis withdrawal is real, documented in research, and one reason cutting down can feel harder than people expect, even when someone genuinely wants to use less.
Neither tolerance nor withdrawal means someone has a severe problem; they are simply how the body adapts to regular substance use, cannabis included. What they do mean is that cutting back gradually, or getting support for the first week or two, tends to work better than trying to stop abruptly with no plan, especially for anyone using daily or near daily.
Cannabis Legality Varies, and That Is Separate From This Score
Cannabis laws differ widely by state and country, from fully legal recreational use to strict prohibition, and this test does not factor legality into your score at all. The CUDIT-R measures patterns of use and their effects on your life regardless of whether cannabis is legal where you are, because legal status and personal impact are two different questions.
If cannabis is illegal where you live, that carries its own separate risks and considerations worth being aware of, but they are not what this screening measures. Whatever your score, and whatever the law in your area, this page is here to help you understand your own relationship with cannabis clearly, not to judge the choice to use it at all.
Cannabis and Psychosis Risk, Stated Carefully
Research has found an association between heavy, frequent cannabis use and an increased risk of psychosis, with one large meta-analysis finding the heaviest users had roughly four times the odds of a psychotic outcome compared to non-users, and the risk rising with the level of use. This is a real, documented association at a population level, particularly for high-potency products used frequently starting in adolescence or young adulthood.
An association is not the same as a guarantee for any individual, and most people who use cannabis, including regularly, do not develop psychosis. That said, if you have a personal or family history of psychosis, schizophrenia, or bipolar disorder, or if you have noticed unusual perceptual experiences, this is worth discussing honestly with a doctor. The Psychosis & Schizophrenia Screening looks at this territory in more depth if it feels relevant to you.
Methodology & sources
The 8 items in this test reproduce the Cannabis Use Disorders Identification Test-Revised (CUDIT-R; Adamson et al., 2010) exactly as published, including the exact response option wording for each item. Items 1 through 7 are scored 0 to 4 using frequency-based response options; item 8 uses a three-option scale scored 0, 2, or 4. The CUDIT-R is in the public domain and free to use with appropriate citation, which is why this page reproduces it word for word rather than adapting it.
This page displays the published 0 to 32 total, but is careful about what the cutoff actually is. The widely repeated figures, 8 or more for hazardous use and 12 or more for possible cannabis use disorder, are scoring-sheet guidance rather than a cutoff tested in the 2010 validation paper; the 8 in particular traces back to the earlier 10-item CUDIT (Adamson and Sellman, 2003). The cutoff that is validated against a clinical sample is 13 or higher, which correctly identified DSM-IV cannabis dependence with 91.3 percent sensitivity and 90.0 percent specificity in 144 treatment-seeking patients with co-occurring depression (Bonn-Miller et al., 2016, drawing on the Adamson et al., 2010 dataset).
There is no single cutoff that fits everyone. Later studies in different populations have found the optimal score shifts by who is being screened: about 9 in a community sample of young adults, 10 in veterans, and 12 in a youth clinical sample. This page treats 13 as the clinically validated reference point while showing your exact score, since a self-report screener taken online is not the same as a clinical sample. This is a screening tool for education and self-reflection, not a diagnostic instrument. Only a qualified clinician can diagnose cannabis use disorder, which requires a full clinical assessment beyond a self-report questionnaire.

Cannabis Use Disorder Test (CUDIT-R) FAQ
What is the CUDIT-R?
The CUDIT-R is an 8-item, validated screening questionnaire developed by Adamson and colleagues in 2010 to identify hazardous cannabis use and possible cannabis use disorder. This page reproduces the 8 items and the published scoring exactly as published.
What does my score mean?
The CUDIT-R total ranges from 0 to 32. The cutoff actually validated against a clinical sample is 13 or higher, which correctly identified cannabis use disorder with about 91 percent sensitivity and 90 percent specificity (Bonn-Miller et al., 2016). Scores from roughly 9 to 12 fall in a range other studies use as their own population-specific cutoff, so treat that band as worth attention rather than a fixed line. This is a screening indicator, not a diagnosis.
Is cannabis use disorder the same as being addicted?
Cannabis use disorder is the clinical term, and it involves a pattern of use causing real problems, tolerance, and difficulty cutting down despite wanting to. Not everyone who uses cannabis regularly meets this threshold, and this test cannot diagnose it; only a clinician can.
Is this test judgmental about cannabis use?
No. This page is built to give you an honest, research-based read on your own use, not to moralize about cannabis or push a particular conclusion. Whatever your score, the goal is clarity, not judgment.
Is this test a diagnosis?
No. Only a qualified clinician, such as an addiction counselor, psychologist, or physician, can diagnose cannabis use disorder through a full clinical assessment. This screening is for education and self-reflection only.
Is the test really confidential?
Yes. The test runs and is scored in your browser, and your individual answers are never sent to us. We count completions anonymously, and if you request the free PDF or a report we receive your summary scores with the email you give us, never your answers. No account is needed.
