Methamphetamine (P)

A book ‘Secrets of Methamphetamine Manufacture (3rd ed.)’ by Uncle Fester, made the top 20 list of books supplied online by Amazon to New Zealand book buyers in 2002.

Since then the Government has been combating methamphetamine use with some positive results.

New Zealand’s Prime Minister, John Key, discusses the 2013 Progress Report.

"When the Government began this plan in 2009, New Zealand had one of the highest prevalence rates of P use in the world, with 2.1% of the population using the drug.

"The latest data [from the 2013 Progress Report] shows this rate has more than halved to 0.9%. While this is positive, the reality is there are still around 25,000 longer-term, heavy users of the drug, who are locked in a cycle of dependence, causing misery and angst for them, their families and loved ones,” says Mr Key.

Every time you use it, it’s bruising your brain

Neuro-imaging studies have demonstrated that methamphetamine use causes changes in the activity of your body’s dopamine system. Dopamine is a neurotransmitter that carries messages from one region of the brain to another.

These changes to the dopamine system can be associated with reduced motor speed (the speed at which muscles react) and impaired verbal learning.

Studies in chronic methamphetamine abusers have also revealed severe changes in areas of the brain associated with emotion and memory.
