How America's $30 billion Legalized Cannabis Industry Is Causing An 'Explosion' Of Teenage Users

Pro-marijuana campaigners achieved mixed results on election night, with voters in Maryland and Missouri backing access to recreational pot, while those in Arkansas and North and South Dakota set to reject their ballot initiatives.

With most of the votes counted, weed looks set to become legal for those aged over 21 in those two states with a combined population of more than 12 million people.

In Maryland, 65.5 percent of votes were cast in favor of cannabis, with 34.5 percent against, as of Wednesday morning. Missourians backed legalization by a slimmer margin of 53.1 percent in favor and 46.9 percent against.
