America's northern neighbor plans to legalize recreational marijuana by July 2018. The government's proposal would permit small marijuana possession at the age of 18 and allows provinces to determine regulations on distribution and vendors. Some marijuana growers in Canada are excited to corner the market legally. Opponents in the U.S. worry about border control, as the bill applies to non-Canadians and could attract American citizens. USA Today says, "Bringing marijuana products across the border could cause confusion for citizens of both countries: Americans who may cross back into the U.S. still under the influence, and Canadians who enter the U.S. unwittingly in possession of marijuana."
