If you research "CBD affects on mental health" you'll probably come to the same conclusion. CBD attaches to the same CB-1 receptors as THC and can mitigate the anxiety inducing affects of high THC dosages.
The reason this is surprising is because THC is the psychoactive ingredient in weed.
CBD is mostly accepted as a milder agent, and has had medications containing it approved by the FDA, like EPIDIOLEX.
