Let's start with the most officially proven medical use of CBD. Earlier this year, the FDA approved the first-ever drug containing CBD, Epidiolex, to treat two rare forms of pediatric epilepsy. To get to that point, the drug's manufacturers had to do a whole lot of randomized, placebo-controlled trials on humans. They had to study how much children could take, what would happen in case of overdose, and any possible side effects that would occur.
THC is the most well-known cannabinoid because of its psychotropic properties—it gets you high, and that’s because of the way that it interacts with the endocannabinoid system. Although high THC levels are often huge draws for pot consumers, too much THC can have negative effects including paranoia, anxiety, and panic attacks. Additionally, there is a huge market purely interested in the therapeutic aspects of cannabis, not the psychoactive ones.
Third-party testing: Once a CBD oil is manufactured, CBD oil companies will often submit their products for third-party tests, which are conducted by non-company personnel to ensure the product is safe for public consumption and meets quality standards.CBD oils should always be accompanied with information about third-party tests; best practice is to avoid oils that do not supply these details.
