Crystal Methamphetamine is a colorless,
odorless form of d-methamphetamine, a powerful and highly addictive
synthetic (man-made) stimulant. Crystal Methamphetamine typically
resembles small fragments of glass or shiny blue-white "rocks"
of various sizes. Like powdered Methamphetamine (another form
of d-methamphetamine), Crystal Methamphetamine is used because
of the long-lasting euphoric effects it produces. Crystal Methamphetamine,
however, typically has a higher purity level and may produce even
longer-lasting and more intense physiological effects than the
powdered form of the drug.
Crystal Methamphetamine typically is
smoked using glass pipes similar to pipes used to smoke Crack Cocaine.
Crystal Methamphetamine also may be injected. A user who smokes
or injects the drug immediately experiences an intense sensation
followed by a high that may last 12 hours or more depending on dose
and how the drug is administered.

Crystal Methamphetamine increases arousal
in the central nervous system by pumping up levels of two neurotransmitters,
norepinephrine and dopamine. At low doses, it boosts alertness and
blocks hunger and fatigue. At higher doses, it causes exhilaration
and euphoria. At very high doses, the drug can cause agitation,
paranoia, and bizarre behavior.
Crystal Methamphetamine
use is associated with numerous serious physical problems. The drug
can cause rapid heart rate, increased blood pressure, and damage
to the small blood vessels in the brain--which can lead to a stroke.
Chronic use of the drug
can result in inflammation of the heart lining. Overdoses can cause
hyperthermia (elevated body temperature), convulsions, and death.
Individuals who use Crystal Methamphetamine
also may have episodes of violent behavior, paranoia, anxiety, confusion,
and insomnia. The drug can produce psychotic symptoms that persist
for months or years after an individual has stopped using the drug.
Crystal Methamphetamine users who inject
the drug expose themselves to additional risks, including contracting
HIV (human immunodeficiency virus), hepatitis B and C. Chronic users
who inject Methamphetamine also risk scarred or collapsed veins,
infections of the heart lining and valves, abscesses, pneumonia,
tuberculosis, and liver or kidney disease.
