At sufficient doses (400-600 mg), CBD can alleviate situational anxiety, such as public speaking. Interestingly, cannabis cultivars, or strains, that are high in CBD and low in THC are better than other cultivars for alleviating depression. But when used over a long period of time, any kind of cannabis could make depression worse. Although clinical trials in people haven’t yet been completed, there is very compelling “petri dish” evidence that CBD can reduce inflammation, for painful conditions such as Crohn’s disease, and fight some cancerous tumors. There is a massive amount of scientific research being done on CBD right now, and we are likely to see many medical breakthroughs in the next decade.
