Abstract
This paper aims to describe cocaine use, markets and harms in Australia from 2003 to 2019.
Outcome indicators comprised prevalence of use from triennial household surveys; patterns of use from annual surveys of sentinel samples who use stimulants; and cocaine-related seizures, arrests, hospitalisations, deaths and treatment episodes. Bayesian autoregressive time-series analyses were conducted to estimate trend over time: Model 1, no change; Model 2, constant rate of change; and Model 3, change over time differing in rate after one change point.

Cocaine use, availability and harm have increased, concentrated in recent years, and accompanied by increased treatment engagement.
