Cannabis clinical trials at UCSD
3 in progress, 2 open to new patients

  • Trial of Dronabinol and Vaporized Cannabis in Neuropathic Low Back Pain

    open to eligible people ages 19-70

    This study will involve treating low back pain associated with nerve injury with oral delta-9-tetrahydrocannabinol (Δ9-THC) or whole plant cannabis for eight weeks. Research subjects will consume either oral Δ9-THC (dronabinol), vaporized 3.7% Δ9-THC/5.6% CBD, or placebo. An analysis will then be determined to assess the risk--benefit ratio of dronabinol and vaporized 3.7% Δ9-THC/5.6% CBD .

  • Using a Field Performance Test on an iPad to Evaluate Driving Under the Influence of Cannabis

    open to eligible people ages 21-55

    This study was authorized by the California Legislature (Assembly Bill 266, the Medical Marijuana Regulation and Safety Act (73) to help with detection of driving under the influence of cannabis. One hundred and eighty healthy volunteers will inhale smoked cannabis with either 0% (placebo), 5.9%, or 13.4% Δ9-THC at the beginning of the day, and then complete driving simulations, iPad-based performance assessments, and bodily fluid draws (e.g., blood, saliva, breath) before the cannabis smoking and a number of times over the subsequent 6 hours after cannabis smoking. The purpose is to determine (1) the relationship of the dose of Δ9-THC on driving performance and (2) the duration of driving impairment in terms of hours from initial use, (3) if saliva or expired air can serve as a useful substitute for blood sampling of Δ9-THC in judicial hearings and (4) if testing using an iPad can serve as a useful adjunct to the standardized field sobriety test in identifying acute impairment from cannabis.

  • Effect of Cannabis and Endocannabinoids on HIV Neuropathic Pain

    Sorry, not yet accepting patients

    Acute cannabis administration is reported to alleviate HIV neuropathic pain (HIV-NP), but there is limited knowledge about the effects of cannabis constituents (delta-9 tetrahydrocannabinol/THC and cannabidiol/CBD), the consequences of long-term cannabis use, and the impact of cannabis on endocannabinoid (EC) function in people living with HIV- NP. Our objective is to address these three fundamental gaps in our knowledge by: 1) examining the acute effects of various CBD/THC products on HIV-NP, 2) utilizing a mHealth text messaging protocol, Individual Monitoring of Pain and Cannabis Taken (IMPACT) to monitor daily real-world cannabis use and changes in pain; and 3) studying the relationship between cannabinoids, EC biomarkers, and chronic neuropathic pain
