Cannabis (marijuana, weed, buds, pot, dope, chronic, trees) is New Zealand’s most commonly used illicit drug. It comes in a dried plant, resin, or oil form. The two main ingredients are tetrahydrocannabinol (THC) and cannabidiol (CBD).

The psychoactive potency of cannabis depends on its concentration of THC, while CBD can reduce pain and anxiety but is not psychoactive. Cannabis is a depressant, which means it slows down your physical and mental reflexes.
