COCAINE and ecstasy use has risen sharply, along with a surge in drive-by shootings, as crime rates fall overall, according to the latest data.

Figures released yesterday from the NSW Bureau of Crime Statistics and Research show that Canterbury-Bankstown and the North Shore have emerged as hotspots, with crime rising in three categories in each, while the largest decline was recorded in the inner city followed by the central western suburbs.

Across the state, Sydney had the biggest decline in crime overall, with falls in robbery - with or without a weapon - break and enter, motor vehicle theft, stealing from a motor vehicle and stealing from a person.

Possession and use of cocaine surged by 63.3 per cent in the 24 months to March, which was outpaced by a 72.3 per cent leap in the possession and use of ecstasy. The possession and use of cannabis was up a more modest 18.3 per cent, with the possession and use of other drugs rising 29.4 per cent.

The head of the NSW Bureau of Crime Statistics and Research, Dr Don Weatherburn, said figures for other crimes such as offensive conduct and language had risen.
