Ice (crystal meth)

What is ice?

Ice (crystal meth) is an illegal methamphetamine, a member of the amphetamine family of drugs. It is very addictive and is linked to chronic physical and mental health problems.

Ice is a central nervous system stimulant that affects the messages sent between your body and your brain.

It is purer and more powerful than other types of methamphetamine, such as speed.

It comes as little crystals that look like ice, or as a white-to-brownish, crystal-like powder. It has a strong smell and bitter taste. It can be:

• injected
• smoked
• snorted
• swallowed

Ice is also known as:

• crystal meth
• meth
• shabu
• crystal
• glass
• Tina
• shard

What are the effects of taking ice?

Ice produces an intense rush that can make you feel happy, confident, energetic and alert.

You may also:

• have an increased sex drive
• feel itchy
• have enlarged pupils
• have blurred vision
• grind your teeth
• have a fast heartbeat
• sweat excessively
• have a dry mouth
• shake and tremble
• feel anxious

These effects can last for up to 12 hours.

Ice can affect people differently based on:

• how much they take
• how strong it is
• the person’s size, height and weight
• whether they are used to taking it
• whether they take other drugs at the same time

What can go wrong with ice?

Coming down from using ice may take several days. People who are ‘coming down’ may:

• feel exhausted
• have difficulty sleeping
• have a reduced appetite
• have headaches and dizziness
• feel paranoid or confused
• hallucinate
• feel very irritable and sad

High doses of ice and frequent use can cause ‘ice psychosis’, which can last a few days, causing:

• severe paranoid delusions and hallucinations
• unusual, aggressive or violent behaviour

People who take a large amount or a strong batch of ice are at risk of overdose. The signs of overdose include:

• heart palpitations
• chest pain
• breathing problems
• seizures
• uncontrolled jerking
• being very agitated and confused
• clumsiness
• sudden, severe headache

An overdose can lead to:

• cardiac arrest
• unconsciousness
• death

Can ice cause long-term problems?

People who use ice repeatedly can develop problems including:

• paranoia
• memory loss
• difficulty sleeping
• extreme weight loss
• dental problems
• regular colds
• trouble concentrating
• stiff muscles
• heart problems
• kidney problems
• depression
• stroke

People who use ice regularly may also:

• look much older than they are
• find everyday activities less enjoyable
• have rapid mood swings
• become depressed and easily stressed
• be susceptible to social, work and financial problems

People who snort ice are at higher risk of

• nosebleeds
• sinus problems
• damage to the nose

People who inject ice and share needles are at greater risk of:

• tetanus
• blood-borne infections such as hepatitis B, hepatitis C and HIV
• vein damage
• endocarditis (a heart infection that can cause damaged heart valves)

What if I use other drugs or alcohol together with ice?

Using ice along with drugs like speed or ecstasy increases the risk of a stroke.

A person is at an increased risk of overdose if they use ice with:

• alcohol
• cannabis (marijuana)
• medicines called benzodiazepines

Can I become dependent on ice?

People quickly need larger doses of ice to produce the same effect, making ice highly addictive.

Some users may feel like they need the drug just to get through the day. This can impact their:

• life
• work
• relationships

People can also become dependent on ice. They may find it difficult to stop using ice or control how much they use. This is often due to withdrawal symptoms.

Withdrawal can be difficult and can lead to:

• cravings
• increased appetite
• confusion
• irritability
• aches and pains
• exhaustion
• sleep problems
• anxiety
• depression
• paranoia
• psychosis

How can I stop using ice?

Getting off ice can be difficult. If you are struggling with withdrawal, speak with your doctor. They can help you manage withdrawal symptoms, and advise you on treatment options, such as:

• support groups
• counselling and therapy
• referral to an addiction specialist
• inpatient detox and rehabilitation
