Marijuana - Health Effects for All

Health Effects for All

Marijuana, hashish (hash) and hash oil all come from the Cannabis Sativa plant, a type of Hemp plant. All three contain tetrahydrocannabinol or THC, a chemical that changes the way you think, feel and act.

The Marijuana grown today is much stronger than in the past. Today, the level of THC found in marijuana is between 6%-30%. In the past levels the levels of THC found in marijuana were close to 0.5%-3%.

Marijuana is made from the dried leaves and flowering tops of the plant. Before the Cannabis Sativa flowers mature, they become coated with a sticky resin. This resin can be dried to make hash. Marijuana can be smoked, or eaten in baked goods.
