First, here’s a quick primer on the science behind marijuana/cbd. This herb works because it contains different cannabinoids, two of which you’ll see most often:
Cannabidiol (CBD). CBD has a number of health benefits, and is nonpsychoactive, meaning it doesn’t cause you to feel “high.”
Tetrahydrocannabinol (THC). THC, a psychoactive cannabinoid, is primarily responsible for that “high” feeling.
Something else THC is responsible for? Inducing sleep. So you’ll want a strain that contains more THC than CBD.
