Earliest Known Psychoactive Cannabis Use Discovered in 2,500-Year-Old Tomb
A round the world, approximately 147 million people use cannabis. For many of them, the goal is to feel the effects of the plant’s psychoactive compound, ∆-9 tetrahydrocannabinol, better known as THC. While today it’s no mystery that marijuana can get you high, it’s unclear when humans made this discovery. On Wednesday, in Science Advances, an answer emerged: Humans have used cannabis for its psychoactive effects for at least 2,500 years.
