Cannabidiol for reducing heroin's addictive effects and breathing problems

Functional efficacy of cannabidiol in modulating the adverse effects of heroin in primates.

NIH-funded research University of Pittsburgh at Pittsburgh · NIH-11250396

What this research studies

Researchers will give heroin and cannabidiol (CBD) to non-human primates and monitor changes in drug-seeking behavior and breathing. They will compare CBD's effects with clinically used medications such as naltrexone and buprenorphine. The team will run behavioral assays that reflect abuse liability and measure respiratory depression to see if CBD lessens these harms. This primate work builds on rodent findings and is intended to inform whether human trials should be pursued.

Who could benefit from this research

Good fit: People with heroin or other opioid use disorder, or those at high risk of opioid overdose, would be the likely candidates for future clinical trials informed by this research.

Not a fit: People who are not affected by opioid use or who need immediate clinical care are unlikely to gain direct benefit from this preclinical primate research.

Why it matters

Potential benefit: If successful, the work could point to CBD as a treatment that lowers heroin craving and reduces overdose-related respiratory depression.

How similar studies have performed: Rodent studies have shown promise that CBD can reduce heroin-seeking triggered by drug cues, but evidence in humans is still very limited.
