Heroin
SummaryHeroin is a drug that comes from the opium poppy. It is one of a group of very strong pain-killing drugs called narcotic analgesics or opioids. Some opioid drugs are opium, morphine and codeine. There are other human-made opioid drugs, such as pethidine and methadone. These drugs can all be used legally, for medical reasons, but heroin is not legal. Heroin (also called 'smack', 'skag', 'hammer', 'h', or 'horse') is in the class of drugs called 'depressants', because it slows down the brain and the central nervous system.
