Marijuana is a mixture of dry shredded stems, leaves, seeds or flowers from the hemp plant. The active chemical in Marijuana is THC delta-9-tetrahydrocannabinol.


THC stimulates cells in the brain to release dopamine, creating euphoria. It also interferes with how information is processed in the hippocampus, which is part of the brain responsible for forming new memories.
