Ice Addiction

Metamphetamine, sold on the street as 'Ice', is the drug of choice for today's party-going teenagers. Australia has the unhappy privilege of leading the world in metamphetamine usage (followed closely by New Zealand) but most parents and community leaders don't have a clue what they are dealing with.

Methamphetamine is an addictive stimulant that is closely related to amphetamine, but has longer lasting and more toxic effects on the central nervous system. It has a high potential for abuse and addiction. Methamphetamine use is on the rise around the country. It has reached epidemic proportions mainly because it is easy to make using common household items.

Meth is often referred to as speed, chalk, ice, crystal, and glass.

The drug increases wakefulness and physical activity and decreases appetite. Chronic, long-term use can lead to psychotic behavior, hallucinations, and stroke. People who use meth often don't sleep, sometimes for days on end. They lose weight quickly because the drug suppresses appetite.

Meth addicts often have lost some of their teeth, look gaunt, and will have sores on their body from nervous energy they are trying to get rid of.

National health statistics in America report that over 12 million persons have tried methamphetamine, with many of them quickly becoming addicted to the drug.

Methamphetamine is taken orally, intra-nasally (snorting the powder), by needle injection, or by smoking. Abusers may become addicted quickly, needing higher doses and more often.

Methamphetamine increases the release of very high levels of the neurotransmitter dopamine, which stimulates brain cells, enhancing mood and body movement. Chronic methamphetamine abuse significantly changes how the brain functions.

Animal research going back more than 30 years shows that high doses of methamphetamine damage neuron cell endings. Dopamine and serotonin-containing neurons do not die after methamphetamine use, but their nerve endings ("terminals") are cut back, and re-growth appears to be limited.

Human brain imaging studies have shown alterations in the activity of the dopamine system. These alterations are associated with reduced motor speed and impaired verbal learning.

Recent studies in chronic methamphetamine abusers have also revealed severe structural and functional changes in areas of the brain associated with emotion and memory, which may account for many of the emotional and cognitive problems observed in chronic methamphetamine abusers. Taking even small amounts of methamphetamine can result in increased respiration, rapid heart rate, irregular heartbeat, increased blood pressure, and hyperthermia. Other effects of methamphetamine abuse may include irritability, anxiety, insomnia, confusion, tremors, convulsions, and cardiovascular collapse and death.

As we've already indicated, long-term effects may include paranoia, aggressiveness, extreme anorexia, memory loss, visual and auditory hallucinations, delusions, and severe dental problems. Also, transmission of HIV and hepatitis B and C can be a consequence of methamphetamine abuse. Among abusers who inject the drug, infection with HIV and other infectious diseases is spread mainly through the re-use of contaminated syringes, needles, and other injection equipment by more than one person.

The intoxicating effects of methamphetamine, however, whether it is injected or taken other ways, can alter judgment and inhibition and lead people to engage in unsafe behaviors. Methamphetamine abuse actually may worsen the progression of HIV and its consequences; studies with methamphetamine abusers who have HIV indicate that the HIV causes greater neuronal injury and cognitive impairment compared with HIV-positive people who do not use drugs.

Meth is a scary drug with horrible health implications. It is easy to manufacture, relatively cheap to buy, and one of the most deadly forms of illicit drug ever to hit the streets.
