Short-term effects of drug abuse on the body and mind

Stimulants such as cocaine and methamphetamine can increase heart rate, blood pressure, and breathing, while also causing heightened alertness, euphoria, and decreased appetite. Depressants like alcohol and benzodiazepines can slow down heart rate and breathing, leading to slurred speech, confusion, and impaired coordination. Opioids such as heroin and prescription painkillers can cause drowsiness, slowed breathing, and decreased pain perception. Marijuana can cause impaired memory, judgment, and coordination, as well as altered perception of time and mood swings.
