Vic police catch 1970 ice affected drivers

Almost 2000 Victorian drivers were caught under the influence of ice last year.

Victoria Police figures show an average 38 drivers a week were detected on the drug, a more than 30 per cent increase on 2013.

Overall, more than 3500 drug affected drivers were caught on the state's roads in 2014, up almost 1000 in a year.

Premier Daniel Andrews says an increasing number of drug users will be detected as police step up drug testing.

"Sadly the more testing we do, the more people we're going to find because this is in our community," he told 3AW radio.

He said the government would be open to increasing penalties as a deterrent.

"If in talking to (Victoria Police chief commissioner) Graham Ashton and others and they say to me 'look we need tougher penalties around drug driving' - then absolutely we'll do what needs to be done there," he said.

Ice accounted for more than half of all drug detections by police in 2014.

Cannabis was a distant second with police catching 805 affected users.

More than 600 people were caught driving while on a cocktail of drugs.

The majority of drug drivers fell into the 26 to 35 age group.
