Tasmanian police are catching more drug drivers than drink drivers.
Police reported detecting 2206 drug drivers around the state in the 11 months to the end of May.
That was up from 2007 in the corresponding period a year earlier.
Meanwhile, detected drink driving offenders decreased from 2021 to 1744 (13.7 per cent).
The 10 per cent spike in drug driving detections was driven by significant increases in the police Western District (476 to 622) and Southern District (965 to 1028).
Drug drivers caught in the Northern District decreased from 560 to 549.
Detections of drink drivers decreased in all three districts.
Figures on how many of the offenders were found to be both drink and drug driving offenders were not available.
Ninety-five drivers refused breath and/or blood analysis during the period.
Police recorded 133 dangerous and reckless driving offenders during the 11 months, which was a slight increase on the previous corresponding period.
The Northern District was the only one with fewer such offenders than previously.
The number of unregistered vehicle offenders shot up from 4647 to 5539, with increases in all three districts.
Police clamped or confiscated the vehicles of 70 hoons, 410 drivers who evaded police, 70 people driving while disqualified and 27 drivers exceeding a speed limit by at least 45 km/h.
Offences against police had declined in all five categories, but still tallied 969 - nearly three per day - during the 11-month period.
That included 183 assaults of police, 381 instances of threatening, abusing or intimidating police, 319 instances of resisting police, 70 instances of obstructing police and 16 criminal code offences.
The figures suggested Tasmanians were becoming noisier or less tolerant of noise, or both.
Police attended 4400 noise disturbance incidents during the period, up from 3856 in the corresponding period a year earlier.
Such incidents increased in all three police districts.
Offensive behaviour incidents decreased by 306 statewide to 3731, despite a slight increase in the Western District.
Vandalism incidents decreased in all three districts, with the statewide total falling from 1590 to 1075.
Public disturbance incidents also decreased in each of the districts, and dropped by 1024 to 4498 statewide.
Overall offence numbers decreased in the Central West, Hobart, Glenorchy, South-East and Bridgewater police divisions, but increased in all the others.
The biggest increase (27.3 per cent) was in the Launceston division.
