Roger Morgan, who is spearheading the campaign against legalization, says cannabis really is a "killer weed."

As Bernie Sanders continues to cut Hillary Clinton’s lead en route to the Democratic presidential primaries, Martin O’Malley joins his fellow candidates for tonight’s Democratic debate. While the candidates will have plenty to say about very serious issues like health care, immigration, and unemployment, a politician’s stance on the use of medical marijuana and the legalization of recreational pot has become a more common issue of interest. Now that many states are legalizing medicinal (and sometimes recreational) marijuana, and members of Congress are introducing legislation to end the federal prohibition on medical cannabis, it’s a question all candidates must have an answer for.

Washington State’s newly legal cannabis capitalists don’t tend to agree on much. Ask any one of them about any current pot-business topic—the regulation of medical marijuana, indoor versus outdoor grows, whether labs fudge pesticide and potency test results for favored clients—and you’ll find yourself in the middle of a passionate harangue. But the more you talk to them, the more they seem to agree on one refrain: However volatile our market might seem, and however much investment capital is sloshing around trying to turn itself into profit, the big bucks haven’t even shown up yet.

Could your next job be in the legal marijuana industry? It's already the fastest-growing business in the U.S. and is expected to generate $10.8 billion in sales in 2019, a huge increase from $2.7 billion seen in 2014, according to Arcview Market Research.

About two dozen states have legalized medical marijuana. Colorado, Alaska, Washington State and Washington, D.C., permit recreational use of cannabis. Support for decriminalization of pot also is surging. A recent survey by Pew found that 54 percent of Americans support the idea.

TORONTO — Ross Rebagliati had just finished smoking his seventh joint of the day. But he was not high, he said, or stoned, or baked or whatever else one might assume another human being would be after smoking their seventh joint of the day — by 3:30 pm.

Marijuana activists are asking London police not to harsh their buzz Monday.

But police say anyone who lights up at a protest in Victoria Park could end up locked up.

The warning comes as pot proponents in cities around the globe, including London, prepare to celebrate cannabis culture on April 20, an annual day known as 420.

Organizers of London’s demonstration in Victoria Park are calling on police to drop the zero-tolerance policy enforced in the past.

“The zero-tolerance policy is expensive, unnecessary and increases the risk to public safety,” organizer Eric Shepperd said.

“It’s only going to cause more harm.”
