Methamphetamine aka crystal aka syabu aka ice, what it can do to you!!!!!!!
Methamphetamine aka crystal aka syabu aka ice and so on is a highly addictive drug, whether injected, snorted or smoked, that affects the brain and central nervous system. Its increase levels of the neurotransmitter dopamine, which stimulates brain cells, enhancing mood and body movement. When methamphetamine is injected or smoked it immediately produces an intensely pleasurable sensation known as a “rush” or a “flash” by releasing high levels of dopamine in the brain. Snorting methamphetamine produces an euphoric sensation, but not a rush.
Unlike other drugs, a methamphetamine overdose gives no immediate signs to users. Users can take a lethal dose and not immediately realize that they have just done so. An overdose results in a rapid onset of physiological deterioration, eventually leading to a heart attack or stroke. Because of the rapid onset, death occurs suddenly and unexpectedly. A meth overdose produces profuse sweating, rapid breathing, increased heart rate and dilated pupils. A person who has overdosed on meth with have a high temperature, kidney failure and cardiovascular collapse — and it will all happen very quickly.
Methamphetamine is highly addictive and users become physically dependent upon the drug quickly. Meth, like amphetamine, produces a rapid pleasurable feeling, which is followed by feelings of depression and irritability when the drug wears off. Users will seek and use more methamphetamine in order to get back to that state of pleasure, or to just feel “normal” again, which results in a physical dependence on the drug. It is a never-ending cycle.
