 Meth was first introduced in Japan in 1893 by a chemist named Nagayoshi Hagai.  1919 crystallized meth was introduced by adding red phosphorus and Iodine.

 colorless, odorless form  powerful and highly addictive synthetic (man-made) stimulant.  Clear crystal chunks, similar in appearance to actual ice or glass  individuals of all ages  gaining in popularity as a club drug  most abused hard drug on the earth,  about 26 million users worldwide 

 smoked in glass pipes  It may be injected (either dry or dissolved in water)  snorted  Swallowed  inserted into the anus or urethra  Meth stays in the system eight to twelve hours long  'Red, White, and Blue Process'  The red is red phosphorus  white is the ephedrine or pseudo ephedrine,  and blue is iodine used to make hydroiodic acid.  Making crystal meth usually involves reducing ephedrine or pseudo ephedrine, found in cold and allergy medicine  watch?v=L9oIQ7hvo-I watch?v=L9oIQ7hvo-I

 Euphoria  Increased energy and alertness  Diarrhea and nausea  Excessive sweating  Loss of appetite, insomnia, tremors, jaw-clenching  Agitation, irritability, talkativeness, panic, compulsive fascination with repetitive tasks, violence, confusion  Increased libido  Increased blood pressure, body temperature, heart rate, blood sugar levels, bronchodilation  Constriction of the walls of the arteries  In pregnant and nursing women secreted in breast milk

 Brain damage  Sensation of flesh crawling (fornication)  Paranoia, hallucinations, delusions, tension headache  Muscle breakdown which can lead to kidney damage or failure  "Meth Mouth" where teeth rapidly decay and fall out  Drug-related psychosis  Death due to stroke, cardiac arrest or elevated body temperature (hyperthermia) 

 contains chemical compounds that over work the central nervous system  It causes nerve damage that produces degeneration of brain tissue (like Alzheimer's)  dopamine is stimulated by crystal meth  Dopamine receptors fire neurons that recycle pleasure receptors.. Afterwards, cell receptors weaken, and pleasure is unattainable  Tachycardia and hypertension contaminates blood vessels in the brain  Brain tissue is able to re-grow after several years but many chronic users experience permanent cognitive ability damage.  Positron Emission Tomography (PET) is brain imaging techniques that study methamphetamine brain effects.  PET shows abnormal dopamine neurons are present after three years of abstinence.
