A CBCVote Compass poll released Sept. 29 suggests piano-playing Prime Minister Stephen Harper is tone deaf about cannabis - even when it comes to his own support base.

In August, Harper, who is currently seeking re-election, argued that Canadians don't want cannabis laws changed, and promised to maintain the status quo.

The poll, however, revealed 76 percent of Conservatives were in favour of either legalizing or decriminalizing recreational cannabis.

Over half of the 14,502 respondents said that cannabis should be legalized. Thirty percent favored decriminalization, and only 14 percent said that it should remain illegal.

Positive attitudes toward cannabis reform were consistent across most of Vote Compass' categories, including age, income, and region.

The poll is good news for Harper's principal opponents: Justin Trudeau favors legalization while Thomas Mulcair pledged to decriminalize cannabis immediately upon taking office.
