Cannabis Use Disorder Symptoms

The symptoms of Cannabis Use Disorder aren’t about how the drug makes you feel while high — they’re about the pattern of behavior and consequences that build up around use over time.

The core signs

Clinicians look for things like: needing more cannabis to get the same effect, spending a lot of time obtaining, using, or recovering from it, giving up other activities you used to enjoy, and continuing to use even after it’s caused problems at work, school, or in relationships.

Cravings and loss of control

A strong urge to use, along with repeated unsuccessful attempts to cut back, is one of the more telling signs. Many people describe intending to use “just a little” and consistently ending up using more than planned.

Withdrawal as a symptom

Experiencing physical or psychological withdrawal — irritability, sleep problems, decreased appetite, restlessness — when cutting back or stopping counts as a diagnostic criterion in itself, and is one of the clearer signs that use has crossed into dependence.

Physical symptoms that can point to something more

Heavy, sustained use that meets criteria for CUD is also the exact use pattern associated with Cannabinoid Hyperemesis Syndrome. If cyclical nausea and vomiting have entered the picture alongside these behavioral symptoms, that’s worth looking at through our CHS symptoms checklist.

FAQ

How many symptoms are needed for a diagnosis?

Two or more of the eleven DSM-5 criteria within a 12-month period is enough for a mild diagnosis.

Do symptoms show up immediately or build over time?

Generally they build gradually, which is part of why they’re easy to miss or rationalize in the moment.
