How does crystal methamphetamine get absorbed by the body and get out of the human body?
Crystal methamphetamine is typically ingested orally, smoked, snorted, or injected. Once in the body, methamphetamine is rapidly absorbed into the bloodstream and crosses the blood-brain barrier, leading to its effects on the central nervous system. Methamphetamine is primarily metabolized in the liver and excreted in the urine, with a small amount eliminated unchanged through the breath and sweat. It has a relatively short half-life, with effects lasting from 8 to 24 hours.
