The most common misconception is that using marijuana leads to intoxication and impairment (i.e., getting “high”). In reality, the effects of THC, the principal psychoactive ingredient in marijuana, depend on the dose. A therapeutic effect can often be achieved using a dose low enough to avoid intoxication. More recently, a misconception has emerged that suggests CBD is the “medical” cannabinoid, while THC is the “recreational” cannabinoid. This is not the case. Both compounds can have therapeutic effects.
