Heroin has a long history as being an effective pain killer, used in medicinal practice.

Diamorphine, more commonly referred to as heroin, is an opiate and sits within the morphine family, a drug that originates from naturally-occurring alkaloids found in the opium poppy plant. Opiates are best known for their ability to relieve pain symptoms. Currently in the UK, heroin is a class A substance under the Misuse of Drugs Act 1971, meaning that it is an offence to possess or supply the drug for recreational purposes. Under the Misuse of Drugs Regulations 2001, opiates, including heroin, are subject to schedule 2 regulations, meaning they can be prescribed and legally possessed and supplied by pharmacists and doctors. Drugs within this schedule can also be possessed lawfully by anyone who has a prescription. For more information about drugs and the law, check out Release.
