Experts including Theisen agree that more research is required to determine the interaction between cannabis and nausea
Eloise Theisen, RN, MSN, AGPCNP-BC, faculty member at Pacific College of Health and Science’s medical cannabis program, and president of the American Cannabis Nurses Association, says more research is needed to determine if CBD is truly effective in treating nausea. There have not yet been any double-blind, randomized, controlled studies in humans on CBD and nausea, although there have been preclinical studies to demonstrate that components of cannabis can treat nausea in some respects. Most of the research on cannabinoids and nausea so far has looked at THC, not CBD.
Theisen warns that, because CBD is not regulated, product purity and potency can vary widely. “It is important to research the company for transparency and to review the certificate of analysis (COA) to ensure that the product label matches the final tested product,” said Theisen.
There’s just not enough data yet to know if CBD’s effects on nausea are pharmacologically-based or placebo, but until there is, you can ask your doctor about using THC to treat it.
