Methamphetamines are part of the amphetamine drug family - a group of drugs that stimulate the central nervous system (amphetamine-type stimulants). They can be swallowed, snorted, smoked or injected.

There are different forms of methamphetamine used illegally in South Australia - the crystal form is known as ‘ice’, the powder form is known as ‘speed’ and the paste form is known as ‘base’. The short and long-term effects of all three forms of methamphetamine are similar, but the intensity of effect may vary depending on the form taken and the way it is used. ‘Ice’ has the most intense effects.

For information on the prevalence of methamphetamine use, the associated effects and harms, prevention and early intervention, treatment and where to get help, please see the Methamphetamines - your questions and answers fact sheet (PDF 222KB).
