Opiates

 

Opiates (sometimes called ‘narcotic analgesics') include morphine, codeine, pethidine, heroin and opium. Opiates are ‘depressant' drugs. Depressant drugs 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. This includes physical, mental and emotional responses.
