In small doses cocaine increases sexual arousal and makes orgasms and erections easier. In large doses cocaine intensifies aggressive sexual fantasies but decreases sexual performance. Some people feel increased sexual desire but are less able to achieve erection and orgasm. These pleasurable feelings motivate the user to repeat the high. Larger and larger doses of cocaine are needed to produce the feelings of the first few doses.
Cocaine intoxication occurs when a person smokes, snorts, or injects too much cocaine.
Cocaine users often binge. They take the drug continually over several hours, or even a week. Then they will not use it again until the craving returns, which happens sooner and sooner with prolonged use. People who use cocaine over a long period feel wired, irritable, and depressed. They can't sleep, lose their appetite, and don't feel content with life.
