What is Ice?

Glass, Shabu, Crystal, Crystal Meth, Shard, Crystal Meth, Puff, P.

Ice (Crystal Methamphetamine) is a is a high purity crystalline form of methamphetamine that functions as a stimulant on the body’s brain and nervous system, meaning that it speeds up the messages that are travelling from the brain to the body. Compared to other forms of Methamphetamine (i.e. Speed or Base) Ice is considered the strongest form, making it more addictive and more likely to have harmful side effects compared to the other forms of methamphetamine. 

A synthetic drug, Ice is manufactured from a range of common products including household chemicals and pharmaceutical drugs. Ice will normally come as chunky, small, colourless and odourless crystals. However, depending on how it is cut ice can also come in a white or brownish crystalline powder with a bitter taste and strong smell. Given that Ice is an illegal drug there are no controls on how it is manufactured, which can result in this drug including harmful or unknown ingredients. This impacts the purity of the drug and makes its effects on the body even more unpredictable. 

Ice is generally smoked or injected as the effects of the drug can be experienced rapidly (three to five seconds). It is also swallowed, smoked with other drugs (i.e. cannabis, snow cones), snorted, and heated on aluminium foil and vapours inhaled (chase). 

How do you know Ice use is becoming a problem?

In comparison to other forms of methamphetamine, Ice can result in stronger and longer lasting highs for user and has more serious effects both during (short-term) and after (come-down) use. Ice is therefore regarded as highly addictive and having the greatest potential for a person to become dependent and experience long-term physical and mental health effects. There is no safe level of Ice use. 

If you or someone you know begins to feel the urge to use Ice to get through everyday activities such as study, socialising and work, this can be a warning sign of Ice dependency. A dependency on Ice can have some tell-tale signs, including:

  • Needing higher doses of Ice to get the same effect.
  • Experiencing intense cravings and withdrawal symptoms.
  • Overlooking work, personal life or family to use Ice.
  • Spending a lot of time securing, using or recovering from Ice use.
  • Unsuccessful efforts to cut down.
  • Engaging in criminal activities such as theft to secure money to buy Ice.

How does Ice make me feel?

Irrespective of the manner in which an individual ingests (i.e. smoke, inject or oral) Ice, once it travels to the brain it triggers the circulation of dopamine, serotonin and norepinephrine that produces a rapid and deeply pleasurable effect on the user. These three chemicals are common in the human body as they are responsible for making us feel excited or alert when we engage in interesting and enjoyable activities (i.e. eating food). However, overloading the body with these chemicals can damage how these chemicals are produced and absorbed in the body, which can lead to long-term complications.


The effects of Ice use may vary for everyone based on their health, body type, the amount taken, how frequently is it consumed and whether it is used with other drugs. As such, the effects of this drug vary greatly and the expected outcomes should not be based on someone else’s experience. However, the effects of ice are rapid and can remain for up to 12 hours and impede on sleep for days after using.

The short-term effects of using Ice may include:

The use of depressant drugs (i.e. alcohol or cannabis) as a way to reduce the effects of a come-down may result in a cycle of dependence for all of the drugs that are used.

What to do in case of Ice Overdose or Harmful Use

Please seek medical attention immediately if you or your friends experience any harmful effects of Ice use (i.e. large amount or strong batch that has been ingested). Phone 000 for an ambulance immediately and tell the operator that there has been an overdose. If you are calling about your own use, do not try to hide the fact that you have taken Ice – be completely honest about the amount and how recently it was used. Whilst waiting for emergency services, immediately inform a friend or family member who can support you during this time.

The signs of overdose to be aware of include:

  • Unconsciousness.
  • Racing heartbeat.
  • Severe chest pains.
  • Sudden and severe headache.
  • Breathing problems.
  • Extreme confusion, clumsiness or agitation.
  • Stroke or heart attack.
  • Uncontrollable jerking.
  • Fits.

Fast action could save someone’s life. You can help them by phoning 000 for emergency services and informing them how long ago they took Ice, how much was consumed and form it was. Try to find out if the person has taken other drugs (including alcohol) as this can increase the risk of serious complications. The quicker and more accurate information that is passed on, the easier it is to help someone experiencing adverse effects from Ice. The priority is making sure the person gets the right help immediately in an emergency. Stay with the person and call a friend or family member for assistance immediately. Place the person on their side in a recovery position to prevent risks of choking until emergency services arrive.

Withdrawal and Recovery from Ice

Dependence of any kind can make people feel anxious or scared about giving up using, which can result in the cycle continuing. The best way to reduce the risks of Ice use and dependence and to begin the road to recovery is to reach out and ask for help from medical professionals. Giving up ice can be challenging, as the body and the brain have to adjust to functioning without the drug. Withdrawal and physical detox symptoms can be unpleasant, which may result in strong temptations to use Ice again to avoid these symptoms and feel a sense of being able to get through the day. These symptoms lessening after the first week and in most cases disappearing after four weeks. Withdrawal symptoms may differ from person to person and ranging from mild to severe. These symptoms may include:

  • Intense cravings for Ice.
  • Aches and pains
  • Disrupted sleep and nightmares.
  • Fatigue.
  • Increased appetite.
  • Confusion and irritability .
  • Loss of motivation.
  • Paranoia and hallucinations.
  • Fever.
  • Nausea.
  • Anxiety and Depression.
  • Tremors

It is important to know that relapse is common as individuals navigate the road to recovery. Acknowledging that relapse is not a failure and that recovery is challenging is a great approach to take. Taking each day as it comes is important as there are situations in which withdrawal symptoms may persist for over twelve months and also periods of time in which the desire to use Ice again exists. It can take a long time for a person to feel normal and learn to surf the urges that may arise due to physical, mental and social cues link with Ice Use. Recovery is challenging but not impossible.

Legal Issues

It is prohibited to possess, supply, manufacture and attempt to drive or supervise learner drivers under the influence of Ice in Australia. In most areas of Australia, it is also illegal to use and/or have in your possession tools (i.e. pipes, needle and syringe) that are used to consume Ice.
Many people are unaware that whilst they may not feel the effects of Ice, it may still be present in their system and consequently can be charged with driving under the influence of an illicit drug. Police have the power to use a random roadside drug test to check for ice and other illicit drugs that may be present in an individual’s system. Driving or supervising a learner driver with the presence of Ice in your system is a serious criminal offence.


The legal consequences associated with Ice can vary depending on the seriousness of the drug offence and the personal circumstances of the individual charged. Penalties may include fines, rehabilitation and drug treatment and education programs orders, disqualification from driving, imprisonment and permanent criminal records. Should a criminal conviction occur this may result in negative consequences for an individual’s employment and social (i.e. overseas travel) realms. The information presented here is an overview of the legal consequences associated with Ice and should not be used as comprehensive legal advice for drug offences.
