Australia has the unhappy privilege of leading the world in meth usage (followed very 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 very closely connected with amphetamine, but has longer lasting and more toxic effects on the central nervous system. It has a high potential for misuse and addiction. Methamphetamine use is on the rise around the country. It has reached rampant proportions predominantly because it is easy to make using common domestic ingredients.

Meth is habitually referred to as speed, chalk, ice, crystal, and glass. The drug increases wakefulness and bodily mobility and decreases desire for food. Chronic, long-term use can lead to psychotic actions, hallucinations, and stroke. People who use meth regularly don't sleep, often for days on end. They lose weight rapidly because the drug lessens the hunger.

Meth abusers regularly loose some of their teeth, look gaunt, and will have ulcers on their body from nervous energy they are attempting to get rid of. National health statistics in America report that over 12 million persons have at least tried methamphetamine, with many of them rapidly becoming habituated to the drug.

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

Methamphetamine causes the issue of very high levels of the neurotransmitter dopamine, which stimulates brain cells, escalating mood and body movement. Chronic methamphetamine abuse extensively changes how the brain works. Animal research going back more than 30 years proves that high doses of methamphetamine impair neuron cell endings.

Dopamine and serotonin-containing neurons do not die after methamphetamine use, but their nerve endings ("terminals") are cut back, and re-development appears to be limited. Human cerebral imaging studies have shown alterations in the activity of the dopamine structure. These changes are pertaining to reduced motor speed and decreased verbal learning.

Recent research in habitual methamphetamine abusers has also shown severe structural and practical changes in sections of the brain associated with emotion and recall, which may account for many of the psychological and cognitive complications seen in persistent methamphetamine addicts.

Taking even small doses of methamphetamine can result in increased respiration, rapid cardiac rate, haphazard pulse, elevated hypertension, and hyperthermia. Other effects of methamphetamine abuse may include bad temper, fear, restlessness, misperception, shakiness, fits, and cardiac collapse and death. As we've by now indicated, long-term effects may include suspicion, aggressiveness, life-threatening anorexia, recall loss, optical and audio hallucinations, delusions, and severe dental difficulties. Also, transmission of HIV and hepatitis B and C can be a consequence of methamphetamine misuse.

Among users who inject the drug, contagion with HIV and alternate infectious maladies is dispersed principally through the re-use of contaminated syringes, needles, and different injection equipment by more than one individual. The heady effects of methamphetamine, though, whether it is taken via hyperdermic needle or taken other ways, can modify good sense and inhibition and lead people to participate in unsafe deeds.

Methamphetamine misuse in reality may worsen the development of HIV and its consequences; research with methamphetamine users who have HIV indicate that the HIV causes greater neuronal harm and intellectual damage compared with HIV-positive people who do not use drugs.

Meth is a scary drug with appalling health implications. It is easy to manufacture, reasonably cheap to buy, and one of the most deadly types of unlawful drug ever to hit the streets.
