"Methamphetamine is FDA approved for the treatment of ADHD and exogenous obesity. * It is dispensed in the USA under the trademark name "Desoxyn"[17] and manufactured by Ovation Pharmaceuticals."

"Crystal meth, also called Blade, Crank, Hot Ice, Tina, and Trash, belongs to a large class of Schedule II drugs called methamphetamines. While some methamphetamines have therapeutic value and are prescribed for a variety of reasons such as weight loss, narcolepsy, and ADHD, crystal meth is produced in illegal meth labs and is an illicit 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."

"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 stroke. Chronic use of the drug can result in inflammation of the heart lining. Overdoses can cause hyperthermia (elevated body temperature), convulsions, and death."
