Is Cannabis Dependency Treatable?
Cannabis dependency can be effectively treated, offering various methods and support.

No medication is FDA-approved for cannabis withdrawal. The US has no drug labeled for this condition. Doctors who treat cannabis use disorder use a short list of off-label drugs. The evidence for each is limited. Most trials are small and few have been repeated.

Drugs tested in trials
- Dronabinol (oral THC). A 2007 lab study found lower withdrawal scores. Later trials did not show a gain in quit rates.
- Nabiximols (Sativex). A 2014 JAMA Psychiatry trial found lower withdrawal scores and better retention. The drug is not approved in the US.
- N-acetylcysteine (NAC). Trials used 1,200 mg twice daily. Results on cannabis use are mixed. NAC is sold as a supplement in the US.
- Gabapentin. A 2012 placebo-controlled trial found less cannabis use and lower withdrawal scores.
- Mirtazapine. Small trials report better sleep and lower withdrawal scores.
- Buspirone. Tested at 60 mg per day. Results on abstinence are mixed.
- Clonidine. Used for sweating, chills, and anxiety. Evidence is thin.
What guidelines list first
Psychotherapy comes before medication. Cognitive behavioral therapy and motivational enhancement are first-line care in US and Canadian guidance. Drugs are second-line or add-on options. No drug has enough evidence for routine use.

What to bring to a prescriber
Give the clinician your use pattern: grams per day, years of use, date of last use, and prior quit attempts. Report sleep and appetite changes. These details guide drug choice and dose.
