NEW YORK-U.S. President George W. Bush has again fingered Ottawa for not doing enough to shut down large, homegrown pot operations, citing Canada for a special mention in the White House annual list of 20 worst drug pariahs.

While Bush mentions Canada as a footnote to his rogues' gallery, which includes Myanmar, Venezuela and Bolivia, he mixes in praise for Ottawa's battle against methamphetamines production and its overall co-operation in law enforcement.

Bush must report to Congress each year on notorious drug transiting and producing nations, and the most egregious offenders can face sanctions.

Canada's grow-ops have landed Ottawa in U.S. crosshairs before. "The principal drug concern was the continuing large-scale production of high-potency, indoor-grown marijuana for export to the United States," Bush said in his statement.

Yesterday's release also included some criticism of Afghan President Hamid Karzai, saying his country's security situation will worsen if it does not do more to stop opium production.
