New statistics from the Australian Crime Commission, released on Tuesday, showed an increase in the number of certain drugs seized by police in the territory in 2012-13.

Yet the number of arrests for drug possession and consumption was the lowest per head in the country.

ACT Policing drug and organised crime team detective sergeant Shane Scott said the report showed the unit's targeting of dealers over users had been a success.

''I think what it's indicating to us is that we're hitting the right mark in our strategy towards targeting the right individuals,'' he said.

''Over the last two years we've been … using the intelligence-led model to push our investigations and seizures up and we're sharing information with other jurisdictions at a higher level.''

More than 200 kilograms of cannabis were confiscated in Canberra over the past year, which accounted for 90 per cent of the weight of all illicit drugs seized in the ACT in 2012-13.

Police also captured 243 grams of heroin, 738 grams of amphetamine-type stimulants and 982 grams of cocaine, more of the substance than was taken by police in South Australia, Western Australia, Tasmania and Northern Territory combined.

Also, 1280 grams of steroids were seized by police over the past year, the third-highest amount in the country. But Detective Sergeant Scott said it was important to note the quantity of a drug seized did not indicate its use in the community or its popularity.

''All jurisdictions are reporting a larger seizure rate in terms of meth and cocaine, and cannabis is a staple across all jurisdictions in terms of its use by the public,'' he said. ''I wouldn't say it's definitive.''

Australian Crime Commission chief executive Chris Dawson said people should be pleased at ACT police's success rate.

''The number of seizures are probably telling us that the police in the ACT are having greater success in detection,'' he said.

While seizures were comparatively high, Canberra's arrest rate for drug possession and consumption was very low, less than a third of the national average.

In the ACT, the arrest rate was 14 people per 10,000, despite having the highest proportion of cocaine arrests in the country.

Canberra Alliance for Harm Minimisation and Advocacy manager Sione Crawford said he was concerned at the number of cannabis users being arrested compared to dealers. ''It's not quite as simple as users versus dealers,'' he said. ''Kids get a few ecstasy tablets for the weekend - that mightn't be dealing, but it might be a large quantity.

''Our perspective is that it isn't as simple as dealers versus users.''
