All forms of marijuana are mind-altering; they all contain THC (delta-9-tetrahydrocannabinol), the main active chemical in marijuana. In other words, they change how the brain works. Most of our cannabinoid receptors are located in areas of the brain associated with pleasure, memory, concentration, sensory, and time perception as well as coordination. Marijuana also contains more than 400 other chemicals. Marijuana's effects on the user depend on the strength or potency of the THC it contains.
