Ontario Progressive Conservative Leader Tim Hudak has admitted to smoking pot in his younger days.

Hudak made the admission while at a campaign news conference in Toronto Thursday morning in which he announced a Progressive Conservative government would create a registry of homes that were previously used as marijuana grow ops or meth labs.

"I was a normal kid, I had a normal upbringing, a normal life in university so I experimented from time to time with marijuana," Hudak told reporters. When asked when he last smoked, Hudak replied: "Quite some time ago."

Hudak also said he does not support the decriminalization of possession of small amounts of marijuana.

Ontario Premier Dalton McGuinty has also said he has tried marijuana in the past.
