OTTAWA - A new study has found that Canadians most commonly see drug use and drug dealing as the biggest problem plaguing their neighbourhoods.

The Statistics Canada study looked at Canadians' perception of signs of crime across 12 major cities.

Signs of crime included both physical crime, such as graffiti, litter and vandalism, and social crime, such as loud parties, public drunkenness and prostitution.

Between nine and 19 per cent of people deemed drug dealing and drug use the biggest blight on their neighbourhood.

The least often observed signs of crime were prostitution and people sleeping on the streets.

Overall, nine per cent of people living in Canada's 12 largest cities saw garbage or litter lying around to be a problem in their neighbourhood.
