Marijuana - also called weed, pot, reefer, grass, dope, ganja, mary jane and hash is the drug most often used in this country. It is a mix of dried, shredded flowers and leaves of the hemp plant. Most users roll loose marijuana into a cigarette. Hash users either smoke the drug in a pipe or mix it with tobacco and smoke it as a cigarette.

Ice - a slang term for smokeable methamphetamine, has a translucent rock-like appearance and is a highly addictive and toxic amphetamine.

Heroin - highly addictive drug derived from morphine, is obtained from the opium poppy. It is a "downer" that affects the brain's pleasure systems and interferes with its ability to perceive pain. Heroin can be injected into a vein or a muscle; smoked through a water pipe or standard pipe; mixed in a marijuana joint or regular cigarette; inhaled as smoke through a straw or as powder through the nose. Heroin users quickly develop a tolerance for the drug and need more and more to get the same high.
