What is cocaine?
Cocaine is made from the leaves of the South American coca bush and is a stimulant, which means it speeds up the messages going to and from your brain.
Cocaine is a white powder with a bitter, numbing taste that comes in three main forms: cocaine hydrochloride, freebase and crack.
Cocaine hydrochloride is mixed with other substances and typically snorted through the nose, or injected, rubbed into the gums or added to food and drinks. Freebase and crack cocaine are usually smoked.
Cocaine is also called coke, charlie, pepsi, blow, C and nose candy. Crack cocaine is also called rock, base or sugar block.
People who use cocaine get a rush, making them feel happy, confident and alert. But they also have a racing heart, tremors, reduced appetite, overheating and sweating. People who use cocaine regularly can have fits, poor sexual performance, kidney failure, poor mental function and an increased risk of contracting infectious diseases by sharing needles. Snorting cocaine can also damage the inside of your nose including destroying the septum (middle part) of your nose, leading to collapse of the nose.
An overdose can cause seizures, or a stroke, leading to coma and death. If you think someone has overdosed on cocaine, call triple zero (000) for an ambulance. Ambulance officers don’t have to call the police.
