This is a drug which may be prescribed by a doctor to treat people dependent on opiate drugs such as heroin. It may also be available on the ´underground drugs market´. This is a class A drug. Only legal to possess if prescribed. Known As: Linctus, Amps, Mixture, Tabs, Phy. Looks Like: What it looks like: Methadone comes in three main forms: a thick bright green or yellow liquid; white tablets; ampoules which contain a clear liquid. The tablets and ampoules are often known by their trade name: physeptone. Apparent Positive Effects: It is a painkiller. It is a sedative. It can give a buzz which is less intense but longer lasting than heroin. It produces a warm feeling in the body. It calms the emotions and can make you drowsy. The Downside: It can cause sweating, a dry mouth, constipation and itching. It makes concentration difficult and energy levels low. Users become physically dependent upon it. This causes major issues as with heroin. Withdrawal symptoms are very unpleasant. These include a high temperature, flu like symptoms, feeling shaky and sick, diarrhoea, restlessness, insomnia and anxiety. There is a high risk of overdose in the early stages of use, and when using erratically. Methadone can slow the breathing until it stops. This may affect the brain and can lead to a coma or even death. This drug is sometimes injected which carries its own risks. There is a higher risk of overdose if alcohol is used with methadone.
