Schedule I

Schedule I refers to a classification in U.S. drug policy that includes substances considered to have a high potential for abuse, no accepted medical use, and a lack of accepted safety for use under medical supervision. Drugs like heroin, LSD, and ecstasy fall into this category. Being classified as Schedule I means these substances are illegal to manufacture, distribute, or possess, highlighting concerns about their harmful effects. This classification contrasts with Schedule II substances, which may have designated medical uses but still carry significant risks of abuse and addiction.
