Cannabis appears in different forms. Marijuana is olive green in color and looks like oregano leaves. Other types of cannabis can be different colors (dark brown, red, or even yellow).

Marijuana is usually smoked in a joint, blunt, or pipe. It can also be eaten or made into a punch and even taken as a pill.

Marijuana travels down the windpipe to the lungs. Once in the lungs, the THC passes into the bloodstream and to every cell in the body. Five to ten times more THC enters from this source than from any other.

Marijuana speeds up the heart rate and can temporarily weaken the heart. It can also cause reddening of the eyes. It also causes sleepiness, dry mouth and increased hunger. THC is fat-soluble, and can harm the tissues in the following areas: brain, Lungs, testes, ovaries, and body fat.

If marijuana is consumed it goes to the stomach and broken down. At this point THC enters the small intestines and is then absorbed into the bloodstream.

THC can stay in a person's body for as long as ten to forty-five days after smoking.

Marijuana produces a high feeling of euphoria and a state of relaxation. Reactions may be slower, short-term memory is effected, and at times people have experienced a altered sense of time and distance.

When people smoke marijuana it causes psychological reactions such as confusion, anxiety, panic, paranoia, decreased cognitive functioning and hallucinations.
