According to the Australian Crime Commission's latest drug report, only 9 per cent of Tasmanians over 14 used cannabis, almost half the Northern Territory's rate.

The report used data from the 2010 National Drug Strategy Household Survey, which found amphetamine use ranged from 1.1 per cent in Tasmania to 3.4 per cent in Western Australia.

The commission attributed the results to Tasmania's focus on early intervention for minor drug offenders through the Illicit Drug Diversion Initiative.

"The initiative seeks to divert minor drug offenders away from the criminal justice system,"commission chief executive John Lawler said.

"Some cases require the individual to receive counselling and treatment to assist minor drug offenders to address their drug use issues."

Despite the low rate of amphetamine use, the number of arrests relating to that drug increased from 104 in 2010-11 to 164 in 2011-12.

However, the overall amount of amphetamine seized declined.

Tasmania notched up a record for the most clandestine drug labs found in the state's history.

Eleven of the 15 labs related to amphetamine production.

Tasmania Police Commissioner Darren Hine welcomed the report as a unique contribution to law enforcement.

"The report is the only report of its type in Australia and provides law enforcement agencies and interested stakeholders with a national perspective of the illicit drug market," he said.
