Narcotics are opioid-based drugs that act on the brain’s opioid receptors to relieve pain and often carry a high potential for dependence. Morphine is a textbook narcotic because it is an opioid derived from opium, widely used for severe pain, and well known for its analgesic effects and abuse potential. Cocaine is a stimulant, alcohol is a depressant but not a narcotic in this framework, and marijuana is a cannabis product not classified as a narcotic. So morphine best fits the narcotic category.
