Amphetamine / Methamphetamine


Amphetamines are stimulant drugs which are manufactured from chemicals. Methamphetamine is one of the groups of amphetamine.

As a stimulant drug, amphetamine/methamphetamine speeds up the body’s functions.

Most commonly, amphetamine/methamphetamine drugs come in three main forms: speed, base and ice (crystal methamphetamine).

cocaine 2Speed generally comes in the form of a white or yellow powder, but can also come in tablet form. It is often ‘cut’ with other substances (which can have harmful effects) to dilute it and make it go further.

Base is an oily or wet substance which ranges in colour from white to yellow or brown. It is less common in Australia.

Ice (crystal methamphetamine) is a purer form of methamphetamine, which generally comes in a colourless or white crystal form, or a rough, crystal-like powder. Ice is claimed to be the most highly addictive form of methamphetamine, largely due to its purity, which causes a more powerful and dangerous effect.
