What Works for Treating Substance Dependence: Medications Available for Some Drugs but Not Cannabis

A comprehensive review of randomized controlled trials found effective medications exist for nicotine, alcohol, and opioid dependence, but no approved pharmacological treatments had been established for cannabis or cocaine dependence.

What This Study Found

The review evaluated the evidence base for pharmacological treatments across multiple substance use disorders. First-line medications were available for smoking cessation (nicotine replacement, bupropion, varenicline), alcohol dependence (naltrexone, acamprosate, disulfiram), opioid dependence (methadone, buprenorphine), and pathological gambling (opioid antagonists).

For cannabis and cocaine dependence, no pharmacological treatments had demonstrated sufficient evidence for approval, though multiple compounds were being tested. The review also discussed strategies to improve existing treatments: combining medications, adding psychotherapy, and better matching patients to treatments.

Key Numbers

Effective medications identified for 4 of 6 conditions reviewed. Cannabis and cocaine dependence had no approved pharmacological treatments. Multiple compounds were in testing for both. Strategies to improve existing treatments included polypharmacy and psychotherapy combination.

How They Did This

Systematic review of evidence primarily from randomized controlled trials and meta-analyses. Covered first and second-line pharmacological treatments for nicotine, alcohol, opioid, cocaine, and cannabis dependence plus pathological gambling.

Why This Research Matters

This review highlighted a significant treatment gap: while effective medications exist for nicotine, alcohol, and opioid dependence, cannabis and cocaine dependence lacked approved pharmacological options, leaving clinicians relying primarily on behavioral interventions for these conditions.

The Bigger Picture

The treatment gap for cannabis dependence is particularly notable given increasing cannabis use and legalization. As more people use cannabis and a proportion develop problematic use, the absence of effective medications becomes a larger public health concern.

What This Study Doesn't Tell Us

Reviews of pharmacological treatments may not fully capture the role of behavioral interventions, which are often the primary treatment for cannabis dependence. The landscape of available treatments changes as new trials are completed. The review focused on first and second-line treatments, potentially overlooking emerging options.

Questions This Raises

  • ?Have any cannabis dependence medications been approved since this review?
  • ?Would combination approaches (medication plus therapy) work for cannabis dependence as they do for other substances?
  • ?Are certain subgroups of cannabis-dependent individuals more likely to respond to specific pharmacological approaches?

Frequently Asked Questions

Is there medication for cannabis dependence?

As of this 2012 review, no medications had been approved specifically for cannabis dependence. Several compounds were being tested in clinical trials, but none had demonstrated sufficient evidence for approval. Behavioral interventions remained the primary treatment approach.

What treatments work for other substance dependencies?

Effective medications exist for nicotine (nicotine replacement, bupropion, varenicline), alcohol (naltrexone, acamprosate, disulfiram), and opioid dependence (methadone, buprenorphine). These medications improve outcomes when combined with behavioral support and psychotherapy.
