Summary

The use of cannabis for severe medical conditions is being legalized in different states, increasing the mandate to make cannabis legal for medically ill patients. However, there is a lack of placebo-controlled studies investigating the efficacy of cannabis. Dronabinol (synthetic, oral Δ-9-THC) is FDA approved for the appetite stimulation in AIDS-related anorexia and nausea/vomiting in chemotherapy patients. Nabilone, a synthetic analogue of THC, is approved for nausea/vomiting in chemotherapy patients. These medications have been found to be effective for these disorders, but there remains an interest in studying cannabis, partly due to the numerous cannabinoids contained within the cannabis plant. Among these is cannabidiol, which does not produce subjective effects, but has been shown to have potent anti-inflammatory effects. In addition, there is data indicating that cannabidiol may be effective for neuropathic pain and nausea/vomiting.

The goal is to investigate the effects of high CBD/low THC cannabis on symptoms such as pain, nausea/vomiting, and quality of life in seriously ill participants. While there is data beginning to emerge that cannabis may have a beneficial effect on these symptoms, there are few placebo controlled, double-blind studies. Additionally, the administration of cannabis to medically ill patients may be limited by its subjective effects, such as anxiety, intoxication, or paranoia. Most cannabis available today has high levels of Δ-9-THC (about 15%). By using cannabis that is high in CBD, but low in - Δ-9-THC, it is hypothesized that some of these effects can be avoid, while maximizing the therapeutic effects, if any.
