10. NARCOTICS AND DESIGNER DRUGS Drugs made from the opium plant are called narcotics. Some narcotics are used to treat severe pain. Narcotics are illegal unless prescribed by a doctor. For example, heroin is one of the most addictive narcotics and is always illegal. Heroin is usually injected, and users often share needles.
