What is Methamphetamine?

Methamphetamine comes in three main forms:

methamphetamine crystalsIce/Crystal meth - Translucent crystals, sometimes shards
methamphetamine crystalsBase - White to brown, thick oily substance
   Speed - White or off-white powder

All forms of methamphetamine can be ‘cut’ (mixed) with other substances, which reduce the purity. Sometimes these other substances can also be harmful. Methamphetamine is often contained in pills sold as MDMA/ecstasy.

Table 1: This table describes the different forms of methamphetamine, potency, common names and uses.

Form Also known as Potency Mainly used by
Ice/Crystal meth Shabu, Shabs, Tina, glass, meth, crystal Medium to high; this is normally the most potent form Smoking, injecting
Base Pure, point, wax, meth Medium to high Swallowing, injecting
Speed Go-ey, meth Low to medium Snorting, swallowing, injecting

Ice or crystal usually have higher purity than speed, and for this reason it gives a stronger "high" and lasts longer. It also has stronger side effects while using and in the ‘comedown’ or ‘crash’ phase. There is greater potential for methamphetamine users to become dependent (addiction), develop psychosis, and suffer from long-term physical and mental health problems.

Personal Stories

How many young people have tried Methamphetamine?

According to the 2017 Australian secondary schools' survey, 1 in 100 students (1%) aged 12-17 used amphetamines in the past month.

Is "Ice" use increasing in Australia?

Survey research suggests that methamphetamine use in Australia has not risen significantly in recent years. In fact, usage has been relatively stable since 2007. However, trend data suggests an increase in ice use among users, compared to other forms such as powder or base.

Are harms from "Ice" use increasing in Australia?

While rates of use remain stable, the harms from ice use (e.g. deaths, hospital admissions for dependence and psychosis) have increased.

What are the effects of "Ice"?

Methamphetamine takes effect quickly. The effects can last between 4 and 12 hours, although it can take 1 to 2 days for the drug to completely leave the body.

The effects of Methamphetamine vary, but can be immediate or long term as listed in the table below:

Immediate Long Term
Increased heart rate and blood pressure Dependence (addiction)
Enlarged pupils Dental problems
Increased energy Heart, kidney and lung problems
Feeling of euphoria (a ‘high’) Malnutrition and exhaustion
Aggressive behaviour Depression
Trembling If injected there is an increased risk of infections like Hepatitis C and HIV
Bad headaches and dizziness Paranoia (feeling extremely suspicious and frightened)
A ‘comedown’ (see glossary) Psychosis (see glossary)
Insomnia Stroke
Stomach cramps  
Reduced appetite  
Blurred vision  
Anxiety and panic attacks  
Jaw clenching and teeth grinding
