"What is methamphetamine?
"Methamphetamine is a stimulant drug usually used as a white, bitter-tasting powder or a pill. Crystal methamphetamine is a form of the drug that looks like glass fragments or shiny, bluish-white rocks. It is chemically similar to amphetamine [a drug used to treat attention-deficit hyperactivity disorder (ADHD) and narcolepsy, a sleep disorder].

"Other common names for methamphetamine include chalk, crank, crystal, ice, meth, and speed.

"How do people use methamphetamine?
"People can take methamphetamine by:
"inhaling/smoking
"swallowing (pill)
"snorting
"injecting the powder that has been dissolved in water/alcohol

"Because the "high" from the drug both starts and fades quickly, people often take repeated doses in a "binge and crash" pattern. In some cases, people take methamphetamine in a form of binging known as a "run," giving up food and sleep while continuing to take the drug every few hours for up to several days."
