Crack cocaine

Cocaine is a stimulant that produces a fast and intense feeling of power and energy. Then it wears off (crack wears off in 5-15 minutes) and the user "crashes" and can feel tired, depressed and nervous for days.

Cocaine is so addictive that someone can get hooked after trying it just once and so dangerous that using it just once can make you have a heart attack or stroke and can kill you.
