Quizplus · Accepted Answer

Morphine, heroin, and methadone are all derived from opium. They are all opioids, which means they are depressants that act on the central nervous system to produce pain relief and feelings of pleasure and euphoria. They are not stimulants, do not increase the action of the central nervous system, and are not used to treat ADHD.
