Cannabinol (CBD) and tetrahydrocannabinol (THC) have the same molecular structure: 21 carbon atoms, 30 hydrogen atoms, and 2 oxygen atoms. The arrangement of the atom is the cause for the differing effects on your body.
Despite their similar chemical structures, CBD and THC do not have the same psychoactive effects. CBD is a non-psychoactive compound. THis means it doesn’t produce the “high” associated with THC.
THC binds with the cannabinoid 1 (CB1) receptors in the brain. It produces a high or sense of euphoria.CBD binds very weakly, if at all, to CB1 receptors. In fact, it can interfere with the binding of THC and dampen the psychoactive effects.
CBD and THC have many of the same medical benefits. They can provide relief from several of the same conditions. However, CBD doesn’t cause the euphoric effects that occur with THC. Some people may prefer to use CBD because of the lack of this side effect.
In June 2018, the Food and Drug Administration approved Epidiolex, the first prescription medication to contain CBD. It’s used to treat rare, difficult-to-control forms of epilepsy.
CBD is used to help with other various conditions. As of this writing the FDA has not approved CBD Isolate for the treatment of other conditions.
Likewise, hemp can produce some THC in addition to CBD, so a test could be positive for THC even if you’ve not used it.
