glassWhat is heroin?

Heroin is one of a group of drugs known as "opioids". Other opioids include opium, morphine, codeine, pethidine, oxycodone, buprenorphine and methadone.
Heroin and other opioids are depressants. Depressants do not necessarily make you feel depressed. Rather, they slow down the activity of the central nervous system and messages going to and from the brain and the body.
