What This Study Found

Across multiple pharmacological systems, CBD, gabapentin, galantamine, nabilone plus zolpidem, nabiximols, naltrexone, PF-04457845 (FAAH inhibitor), quetiapine, varenicline, and topiramate all showed some superiority over control conditions in RCTs for CUD. All were reported as safe and tolerable.

Key Numbers

About 1 in 5 cannabis users develop CUD, rising to 1 in 2 for daily users. CUD accounts for 0.69 million disability-adjusted life years globally. Ten medication classes showed some benefit across eight neurotransmitter systems.

How They Did This

Narrative review of randomized controlled trials examining pharmacological interventions for cannabis use disorder, organized by mechanism of action across cannabinoid, glutamatergic, GABAergic, serotonergic, noradrenergic, dopaminergic, opioidergic, and cholinergic systems.

Why This Research Matters

There is currently no FDA-approved medication for cannabis use disorder, despite the condition affecting roughly one in five cannabis users. This review maps the entire landscape of pharmacological candidates that have reached the RCT stage.

The Bigger Picture

The diversity of promising targets across multiple neurotransmitter systems suggests CUD is not a single-mechanism disorder. The field is moving toward combining pharmacotherapy with psychotherapy, and drug repurposing offers faster paths to clinical availability than new drug development.

What This Study Doesn't Tell Us

Narrative review without formal meta-analysis. Individual RCTs varied in sample size, follow-up duration, and outcome measures. Many trials had small samples. "Superiority over control" ranged from modest to meaningful effects.

Questions This Raises

  • ?Which of these medications will prove most effective in larger confirmatory trials?
  • ?Can combinations of medications targeting different systems produce better outcomes?
  • ?Will personalized approaches based on patient characteristics improve treatment matching?

Frequently Asked Questions

Are there medications for cannabis use disorder?

There is no FDA-approved medication yet, but this review found 10 medications (including CBD, gabapentin, nabiximols, and topiramate) that showed some benefit in randomized controlled trials.

What is the best treatment approach for CUD?

According to this review, combining pharmacotherapy with psychotherapy appears to be the optimal approach, tailored on a case-by-case basis.
