Toronto Mayor Rob Ford denied Friday that he smokes crack cocaine and said he is not an addict after a video purported to show him using the drug. Ford did not say whether he has ever used crack.

Ford did not take questions from reporters at a news conference at City Hall held after close allies released a letter urging him to address the purported video. The video apparently shows Ford smoking crack.

"I do not use crack cocaine, nor am I an addict of crack cocaine," he said before going on to criticize the media.
