Users might feel happy, bright and alert after taking cocaine, but there are downsides. Users can feel paranoid and agitated, have hallucinations, take risks, ignore pain and display unpredictable or violent behaviour.
An overdose can cause seizures (fits), a stroke or a cardiac arrest, 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.

Can cocaine cause long-term problems?
Snorting cocaine can also damage the septum (middle part) of the nose, leading to collapse of the nose. Cocaine can harm your baby if you use it while you are pregnant.
Some long-term users may develop psychosis, which makes them paranoid, experience hallucinations or unusual thoughts and behave out of character. These effects usually disappear when the person stops using cocaine.
Long-term users risk social and financial problems, and use has been linked to criminal behaviour.
