Many people may desire the use of medical cannabis but fear any negative side effects. With cannabidiol (CBD) gaining in popularity for its high-safety profile and lack of psychoactive side effects, people wonder whether or not the cannabinoid is worth the hype. According to a new study, led by Dr. Ken Mackie from Indiana University, the answer is yes. In the study, scientists injected two groups of mice with tetrahydrocannabinol (THC), with one group only receiving the THC and the other also receiving CBD. Mice who received only THC experienced greater memory impairment and anxiety over the long term, while those who also received CBD did not experience these effects.

Previous studies surrounding THC and CBD have been mixed, but Mackie believes his study is more accurate because “this is the first study in a rigorously controlled animal model to find that CBD appears to protect the brain against the negative effects of chronic THC.” He continues to explain that this experiment "suggests that strains of cannabis with similar levels of CBD and THC would pose significantly less long-term risk due to CBD's protective effect against THC."

More research is left to be desired to understand how CBD is able to exhibit these effects. This information has been provided by Civilized and approved by our Chief Medical Officer.
