HEALTH RISKS (long term) which includes withdrawal & tolerance:

Methamphetamine releases high levels of the neurotransmitter dopamine, which stimulates brain cells, enhancing mood and body movement. Oral or intranasal use produces euphoria - a high, but not a rush. Users may become addicted quickly, and use it with increasing frequency and in increasing doses.  Tolerance to methamphetamine develops quickly. The effects last from three to four hours. Like amphetamine sulphate, withdrawal is in two phases. Firstly, the "crash" or "come down" which produces tiredness and depression. In the second phase, users can become irritable and severely depressed, this will last for three to four weeks and in some cases can last for months.  Long-term use of methamphetamine can lead to severe weight loss, insomnia, exhaustion, paranoid psychosis (this is generally drug-induced and as such will be resolved within a few weeks after drug taking has stopped) and severe depression. Smoking "Ice" over long periods causes severe psychotic episodes with both visual and auditory hallucinations, presenting not unlike schizophrenia.


Methamphetamine - often referred to as crystal meth - was reclassified as a Class A drug on 18th January 2007. It is illegal to have, give away or sell. As a Class A drug, possession can get you up to seven years in jail and/or an unlimited fine. Supplying someone else, even your friends, can get you life imprisonment and/or an unlimited fine.
