Crystal meth, also known as ICE, is a stimulant drug. Stimulants speed up the messages travelling between the brain and the body. Speed is a powdered form of ice and is not as strong or as addictive. When using ice, the brain releases a chemical known as Dopamine. Dopamine is released during pleasurable activities such as eating and sex. Having just one hit of ice releases 10 times the amount of dopamine as sex.

Flooding the brain with this much Dopamine can overload the brain and cause users to be unable to sleep for days and can even cause psychosis. It also changes the pleasure pathways in the brain and rebuilds them to expect huge amounts of dopamine, this means activities that the user used to find pleasurable such as picnics, spending time with loved ones or skateboarding, no longer interest them.

It can take up to 12 months for the Dopamine receptors to return to normal.
Taking the steps to attend rehab group sessions, counselling, and gain knowledge from Seahaven Private, will set you up for success.

Long-Term Effects of ICE/Methamphetamines

Those who use a large amount or use regularly may see the following effects:

– Extreme weight loss due to reduced appetite

– Trouble concentrating, restless sleep

– Dry mouth and dental problems

– Regular colds or flu

– Breathlessness, muscle stiffness

– Anxiety, paranoia, and violent behaviour

– Depression

– Heart and kidney problems

– Increased risk of stroke

High doses of ICE and frequent use may result in a psychological condition known as ‘ice-psychosis’, characterised by paranoid delusions, hallucinations and bizarre, aggressive, or violent behaviour. These symptoms usually disappear a few days after the person stops using ICE (

Regular users may also feel they need ICE to get through their regular day to day activities, they can become stressed easily and have regular mood swings. These side effects can cause anxiety and depression which can remain up to several months after quitting, this is why support such as rehab is so important to get through this period.

It can take up to two weeks to come down from ICE. During this time, the user can feel completely exhausted, anxious, socially awkward, and uncomfortable in their own skin. The following effects may also be experienced during this time:

  • Difficulty sleeping or exhaustion
  • Headaches, dizziness, and blurred vision
  • Paranoia, hallucinations, and confusion
  • Irritability and feeling depressed or down

To combat the negative effects of coming down after using, people may use alcohol, cannabis, or benzodiazepines such as Valium. This can result in a cycle of dependence on both types of drugs (  Combining cannabis with methamphetamines places enormous stress on the body and can result in overdose as the stimulant effects of methamphetamines can mask the effects of the depressant drugs (

Withdrawal can be a difficult as the body needs time to readjust after being dependent on ICE. Withdrawal symptoms usually are at their most intense in the first week and which proceeds to settle down for approximately a month until completely disappearing.

Some of the symptoms can include:

– Cravings for ICE

– Increased appetite

– Confusion and irritability

– Aches and pains

– Exhaustion

– Restless sleep and nightmares

– Anxiety, depression, and paranoia


If you take a large amount or have a strong batch, you could overdose. Call an ambulance straight away if you have any of the following symptoms. Ambulance officers do not have an obligation to involve the police.  Your wellbeing and safety is their paramount concern:

  • Racing heart and chest pain
  • Breathing problems
  • Fits or uncontrolled jerking

  • Sudden and severe headache
  • Unconsciousness
