CBD is well tolerated in humans with doses up to 600 mg not resulting in psychotic symptoms (15). In the few small placebo-controlled studies performed, no significant CNS effects were noted. Oral CBD undergoes extensive first-pass metabolism via CYP3A4, with a bioavailability of 6%. Following single doses in humans, the half-life of CBD when taken orally is about 1 to 2 days.1 In vitro studies have shown that CBD is a potent inhibitor of multiple CYP isozymes, including CYP 2C and CYP3A (16, 17). Whether these in vitro observations are relevant at plasma concentrations likely to be seen in patients is unclear. In addition, given its metabolism via CYP3A4, clinical trials of CBD in patients receiving enzyme-inducing AEDs, such as carbamazepine or phenytoin, will require detailed pharmacokinetic studies.

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.
Rather, what most of these oils appear to be are extracts of the hemp seed. As we mentioned earlier, CBD oil can be made from either hemp or marijuana cannabis plants. No matter which plant they come from, however, they must be made using the flowers, leaves, stem and stalks of the plant, as these are the parts where the CBD compound is actually located.
