What is Cocaine?
In Australia, Cocaine is known as coke, blow, charlie, C, dust, flake, nose candy, snow, white, crack, rock, freebase.
Cocaine is produced from the leaves of Erthroxylon coca plant, and comes in three main forms:
- A paste which is often off-white or light brown
- A powder which is often white or off-white
- A white or off-white crystal rock known as crack cocaine.
In Australia, cocaine is most commonly in a powder form which is often snorted. As with all powder drugs, it is often sold ‘cut’ (mixed) with other white powder substances which can sometimes be harmful in their own right.
Personal Stories“It started off only occasionally. But soon I was taking cocaine in the morning just to get through the day. My friends stopped talking to me. My girlfriend left me and I had to steal from my own family just to pay for drugs.”
–Francis, 17
