Chronic Pain Clinical Trial
Official title:
An Observational Study of the Effects of Edible Cannabis and Its Constituent Cannabinoids on Pain, Inflammation, and Cognition
This study tests the effects of cannabinoid levels in blood on pain relief, inflammation, and cognitive dysfunction in chronic pain patients who choose to use edible cannabis. Over a two-week period, participants use an edible product of their choice. Blood levels of 9-delta-tetrahydrocannabinol (THC) and cannabidiol (CBD) will be measured before, during, and after the two-week exposure period to determine whether there are associations with pain, inflammation, sleep, physical activity, anxiety/depression, and cognitive dysfunction. After the two-week self-administration period, participants will be followed for six months to collect self-report data on cannabis use, pain levels, sleep quality, and mental health symptoms.
The National Center for Health Statistics reports that approximately 76 million Americans suffer from chronic pain, affecting the lives of more Americans than cancer, diabetes, and heart disease combined. Perhaps because of its ubiquity and the challenge to its treatment, relief from chronic pain is by far the most commonly cited condition by patients for use of marijuana, with 87%-94% of medical marijuana users reporting using for relief of a pain condition. Although the mechanisms are still unclear, marijuana and its constituent cannabinoids, including 9-delta-tetrahydrocannabinol (THC), are thought to be involved in reducing pain and associated inflammation. However, THC is also associated with harm in the form of cognitive dysfunction. Synergistic interactions of multiple cannabinoids are believed to produce different effects on both pain relief and cognitive function as compared to THC alone. For example, cannabidiol (CBD) is another primary cannabinoid that may work synergistically with THC in a multi-target analgesic approach. This study examines the effects of cannabinoids in edible form on pain relief, inflammation, and cognitive dysfunction in chronic pain patients who choose to use marijuana in the context of a short-term (2 weeks), patient-oriented, observational design and a mobile pharmacology and phlebotomy lab. ;
