Crystal methamphetamine (‘ice’) is a stimulant drug, which means it speeds up the messages travelling between the brain and the body. It’s stronger, more addictive and therefore has more harmful side effects than the powder form of methamphetamine known as speed.1
Ice usually comes as small chunky clear crystals that look like ice. It can also come as white or brownish crystal-like powder with a strong smell and bitter taste.1

Ice is generally smoked or injected and the effects can be felt in 3 to 7 seconds. It is sometimes swallowed (15 to 30 minutes to feel the effects) or snorted (3 to 5 minutes to feel the effects).3
There is no safe level of drug use. Use of any drug always carries some risk. It’s important to be careful when taking any type of drug.

Some people who regularly use ice may start to feel less enjoyment of everyday activities. They can get stressed easily and their moods can go up and down quite quickly. These changes can lead to longer-term problems with anxiety and depression. People may feel these effects for at least several weeks or months after they give up ice.9
The effects of taking ice with other drugs − including over-the-counter or prescribed medications − can be unpredictable and dangerous, and could cause:
