This drugs effects are similar to but more rapid than those of amphetamines. Additionally the effects of cocaine are short-lived, which may help explain why this drug is especially addictive both psychologically and physiologically.

Epilepsy is primarily known for causing convulsions. But, seizures can prompt a large variety of symptoms, from staring to falling to fumbling with clothes.
