Cocaine is a highly addictive drug that ups your levels of alertness, attention, and energy. You may hear it called a stimulant. It’s made from the coca plant, which is native to South America. It’s illegal in the U.S. Other names for it include:

  • Coke
  • Snow
  • Rock
  • Blow
  • Crack

It comes in a few different forms. The most common is a fine, white powder. It can also be made into a solid rock crystal.

Most cocaine users snort the white powder into their nose. Some rub it onto their gums or dissolve it in water and inject it with a needle. Others heat up the rock crystal and breathe the smoke into their lungs.
