What is methamphetamine?

Methamphetamine comes in three main forms:

methamphetamine crystals
Ice/Crystal meth - Translucent crystals, sometimes shards
methamphetamine crystals
Base - White to brown, thick oily substance
methamphetamine in powder form
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 on the illicit drug market as MDMA/ecstasy.

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 more potent side effects during use and in the ‘comedown’ or ‘crash’ phase. There is greater potential for methamphetamine users to develop dependence (addiction), psychosis, as well as long-term physical and mental health problems.

How many young people have tried it?

Majority avoid drugs
According to the 2014 Australian secondary schools' survey, 1 in 52 students (1.9%) aged 12-17 used amphetamines last year.

Is "Ice" use increasing in Australia?

Survey research suggests that methamphetamine use in Australia has not risen significantly in recent years, with rates of use reported to be relatively stable since 2007. However, trend data suggests an increase in preference for crystal methamphetamine (ice) use among users, compared to other forms of methamphetamine (e.g. powder, base).

Are harms from "Ice" use increasing in Australia?

While rates of use remain stable, the harms from ice use (e.g. hospital admissions for dependence and psychosis) have increased, aligning with the shift to higher potency forms of methamphetamine (ice) and increases in regular and dependant use.

What are the effects?

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.

 Effects of methamphetamine vary, but may include:

Immediate

  • Increased heart rate and blood pressure
  • Dilated (enlarged) pupils
  • Increased energy
  • Feeling of euphoria (a ‘high’)
  • Aggressive behaviour
  • Trembling
  • Bad headaches and dizziness
  • A ‘comedown’ (see glossary)
  • Insomnia
  • Stomach cramps
  • Reduced appetite
  • Blurred vision
  • Anxiety and panic attacks.

Long Term

  • Dependence (addiction)
  • Dental problems
  • Heart, kidney and lung problems
  • Malnutrition and exhaustion
  • Depression
  • If injected there is an increased risk of infections like Hepatitis C and HIV
  • Paranoia (feeling extremely suspicious and frightened)
  • Psychosis (see glossary)
  • Stroke.
