Amphetamines such as methamphetamine (ice and speed) belong to a group of drugs called stimulants. They work by speeding up the messages between the brain and the body. Their appearance can vary from powder, which can range in colour from white to brown, to an oily paste, or white or clear crystals.

Crystal methamphetamine is also known as ice, shabu, crystal or glass.

Legal Issues of Methamphetamine/Amphetamine
It is illegal to possess, use, supply, manufacture or sell amphetamines in Australia or to help someone else to do these things. Supply includes giving amphetamines to a friend. Penalties can differ in different states and territories but include heavy fines and imprisonment. The exception is if amphetamines were prescribed for you by a doctor for a medical condition and you are using them in the way that the doctor advised.
It is also illegal to drive while under the influence of amphetamines. Police may conduct random drug tests and if the test shows any amphetamines in your system you will be charged. Penalties may include heavy fines, imprisonment and loss of your driving license.
In some states and territories, it is illegal to possess, sell, or purchase equipment such as ice pipes.
