Speed is a street name for a drug that is primarily a form of methamphetamine or amphetamine, which are central nervous system stimulants. Specifically:
- Speed is often methamphetamine in a powder form that is less potent than crystal meth (also called ice)
- It is also used as a general term for amphetamine sulfate, which is chemically related but distinct from methamphetamine
- Both amphetamines and methamphetamines stimulate the brain and body, increasing alertness, energy, and feelings of euphoria, but they are illegal when used recreationally
Speed can be taken by swallowing, snorting, injecting, or smoking, and it causes effects such as increased heart rate, alertness, talkativeness, and decreased appetite. It also carries significant risks including addiction, paranoia, psychosis, and potentially fatal overdose
. In summary, "speed" refers to illicit stimulant drugs that are chemically amphetamines or methamphetamines, with methamphetamine being the stronger and more addictive variant
