Schedule I is the most restrictive category of drugs determined by the Drug Enforcement Administration, ranked the highest in abuse potential and addictive quality.
A highly addictive opioid, heroin originated in Southeast and Southwest Asia, Mexico and Colombia. The drug is made by extracting juice from a poppy flower and transforming the juice into an opium and morphine state, and finally a heroin form. Heroin is usually sold as white or brownish powder, in varying degrees of potency, and is ingested by injecting or snorting. Users may experience an intense high followed by sudden fatigue and confusion.
LSD is a potent hallucinogen made from lysergic acid, a chemical found in ergot fungi. Odorless, colorless and bitter in taste, LSD is usually consumed as a drug-laced blotter paper placed under the tongue. The effects of LSD vary: Dilated pupils, elevated heart rate and blood pressure, and feelings of extreme euphoria, fear or depression are common. A user's judgment is distorted when on an LSD "trip," potentially putting them in dangerous situations.
