Me t h a m p h a t m i n e Residue Testing

It is an addictive stimulant drug that strongly activates certain systems in the brain. m e t h a m p h e t a m i n e is closely related chemically to amphetamine, but the central nervous system effects of m e t h a m p h e t a m i n e are worse. Both drugs have some medical uses, primarily in the treatment of obesity, but their therapeutic use is limited.

Street m e t h a m p h e t a m i n e has many different names such as "speed," "m e t h," and "chalk." Clear chunky crystals resembling ice that can be inhaled by smoking is called m e t h a m p h e t a m i n e hydrochloride. This also has many different names such as “ice”, “crystal”, and “glass”.

 

m e t h a m p h e t a m i n e releases high levels of the neurotransmitter dopamine. This neurotransmitter dopamine stimulates brain cells, enhancing mood and body movement.  It also has a neurotoxic effect, damaging brain cells that contain dopamine and serotonin, another neurotransmitter. m e t h a m p h e t a m i n e appears to cause reduced levels of dopamine,  over time, which can result in symptoms like those of Parkinson's disease, a severe movement disorder.
  

m e t h a m p h e t a m i n es are taken orally or intranasally (snorting the powder), by intravenous injection, and by smoking.  The user experiences an intense sensation called a "rush" or "flash,” immediately after smoking or intravenous injection which lasts only a few minutes.  If the user takes it orally or intranasally, they receive a different sensation called a high.  Users that use m e t h a m p h e t a m i n e s with increased frequency and increased doses may become addicted quickly.
