Saskatchewan justice minister Gord Wyant says he supports decriminalizing marijuana. But he also says the public needs to be protected as well. His main concerns are there’s no way to monitor people who are driving on the roads while impaired by marijuana, and workplace safety if people are operating heavy machinery while impaired by it. Meantime, the federal government is expected to introduce long-promised legislation today that will lead to marijuana legalization and regulation over its sale starting next year. Measures are expected to include limits for legal possession, age restrictions for retailers, marketing rules, tougher penalties for impaired driving, and requiring producers to sell their pot in plain packaging.
