The Bush administration's annual report on international drug trafficking says that Canada has not taken adequate steps to shut down marijuana grow operations across the border, the Toronto Star reported Sept. 19.

The report, which lists Bolivia, Venezuela, and Myanmar among 20 nations blacklisted by the U.S. for failing to address drug trafficking, slams Canada over marijuana but praises the country for its efforts on methamphetamine. Canada was not included on the list of 20 "rogue" nations.

"The principal drug concern [in Canada] was the continuing large-scale production of high-potency, indoor-grown marijuana for export to the United States," Bush said in a prepared statement. Afghanistan also came in for criticism for not doing enough to prevent opium production.
