Remember, because CBD oils are largely unregulated, there is no guarantee that a product is either safe or effective.

CBD’s exact mechanism of action is unclear. Unlike THC, CBD has a relatively low affinity for cannabinoid receptors in the brain. These are the molecules to which THC binds to elicit its psychoactive effects.
What to Look For
According to a 2012 study in the Journal of Experimental Medicine, rats injected with inflammatory chemicals in their hind feet experienced less inflammation and neuropathic pain when treated with an oral dose and spinal injection of CBD.
According to the investigators, men provided 300 mg of CBD exhibited less anxiety than those given a placebo. Interestingly, those provided 100 mg or 600 mg of CBD oil did not.
Common symptoms include:
Since some CBD oils contain trace amounts of THC, you should avoid driving or using heavy machinery when taking CBD oil, particularly when first starting treatment or using a new brand.
