Cocaine is a highly addictive drug made from the leaves of the South American coca bush. Long-term users risk social and financial problems, and use has been linked to criminal behaviour. Users can also become psychotic.
Cocaine comes in three forms: cocaine hydrochloride, freebase and crack. Cocaine hydrochloride is a white powder usually mixed or ‘cut’ with other substances. It is typically snorted through the nose, but it can be injected, rubbed into the gums or added to food and drinks. Freebase is also a white powder, but crack cocaine is generally found in the form of larger crystals. Freebase and crack are usually smoked.
Cocaine is also known as coke, charlie, pepsi, blow, C and nose candy. Crack cocaine is also known as rock, base and sugar block.
Cocaine is a stimulant, which means it speeds up the messages going to and from your brain. Cocaine is highly addictive, and users crave the same experience over and over again. Learn about the many physical health effects of cocaine.

Coming down after using cocaine can take days. Users can feel tense and anxious, depressed and tired, and up and down.
