Amphetamine and Methamphetamine are stimulant drugs. Although amphetamines have some therapeutic uses such as the treatment of obesity, they are more well known as recreational drugs. Common names for these drugs include speed, meth, chalk, ecstacy, ice and glass. Amphetamines are addictive and tolerance can develop, causing the user to need more of the drug to get the same effect.
Long term amphetamine use has been linked to paranoid psychosis, hallucinations, violent and aggressive behavior, weight loss and tremors.
As amphetamine use is usually self-reported, inaccuracies in the data are likely to occur due to:
- The legal status of amphetamine use and the percieved level of enforcement of these laws.
- General public opinion of amphetamine use.
Amphetamine possession (without a doctors prescription), use, supply and manufacture is illegal in most countries including Australia, the United Kingdom and New Zealand.
Countries with high rates of amphetamine use also have high rates of cannabis use but usage rates of common legal drugs such as alcohol (spirits, beer,
wine) and tobacco are not unusually high.
