Premiers meeting in the Yukon say they want quick action from the federal government on the legalization of marijuana to prevent a patchwork of enforcement and distribution across the country.

"There's real concerns," said Manitoba Premier Brian Pallister before heading into the meeting Thursday in Whitehorse.

"It's one of the issues I want to raise today," he said. "I would hope we can develop a national approach, a co-operative approach."

British Columbia's Christy Clark echoed Pallister's worries around public health, safety and distribution.

"We need to see the federal legislation," she said. "We will build a system focused on safety."

Saskatchewan Premier Brad Wall said he's most concerned about consistent enforcement across Canada when it comes to marijuana use.
