Methamphetamine Methamphetamine is a drug that acts more powerfully as a CNS stimulant than amphetamines. Common street names include Speed, Meth, Chalk and Cat. Methamphetamine is sometimes used as a cheap replacement for cocaine. Methamphetamine can be smoked, snorted, injected or taken orally. The effects are similar to amphetamines in that users report being more alert, increased physical activity and speech, heightened respiration and a decrease in appetite.
Many users feel euphoric or an intense rush of pleasure.
Other effects include confusion, apprehension, anxiety and irritability, as well as an inability to sleep. Users may experience physical side effects including tremors, convulsions, high blood pressure, increased body temperature, breathing problems, irregular heartbeat and extreme anorexia, some of which can result in death. Methamphetamine use has also been linked to irreversible brain damage. Use over extended periods of time may lead to deep depression due to a depletion of neurotransmitters in the brain. Withdrawal symptoms include depression, lack of energy and the inability enjoy pleasurable experiences.
