Contrary to what many say, CBD is psychoactive. A psychoactive substance is simply any substance that has a significant effect on the mind. Which CBD does. But that doesn't mean that it will get you high or that it is not safe. Caffeine is also classed as a psychoactive substance. An in depth review from The World Health Organisation found that CBD is non-intoxicating, non-addictive and perfectly safe for regular consumption.
