Marijuana was the main focus of an in-depth injury prevention conference in south London Thursday afternoon.

The 16th annual “Not By Accident” conference, hosted by the Ontario Injury Prevention Resource Centre, ran from 8:15 a.m. to 4 p.m. at the Best Western Lamplighter Inn, and looked specifically at the possible safety implications marijuana’s legalization or decriminalization could have on healthcare workers and society at large.

During last night's Republican debate, Jeb Bush, one of the leading Republican candidates and former Governor of Florida, admitted yet again to smoking marijuana when he was young.

"Forty years ago I smoked marijuana, and I admit it."

This is commonplace now if you're running for President. Clinton admitted it, Jeb's brother George W. admitted it, and so did Obama. Apparently, one of the side effects of marijuana use may be the Presidency of the United States -- use with caution.

And that is the hypocrisy. The hypocrisy that Sen. Rand Paul of Kentucky pointed out on stage last night: "The people going to jail for this are poor people, often African-Americans and often Hispanics, and yet the rich kids who use drugs aren't."

The temporary tax break could cost Colorado up to more than $NZ6m in revenue.

Colorado saw a sales increase last year in all three tax classes of alcohol.

Here’s how it all fits together. By comparison, state alcohol excise taxes raked in about $42m (£27m) – up 2.4% from 2013, the state said. The one-day pot tax holiday came after the state underestimated its overall state tax collections last year.

Curt Steiner, a political consultant and spokesman for Ohioans Against Marijuana Monopolies, said the report is handwriting on the wall if Ohio approves legalizing marijuana for recreational and medicinal use.

SALEM — The Oregon Liquor Control Commission continues to move ahead with implementing its seed-to-sale tracking system for recreational marijuana, despite a lawsuit filed by an unsuccessful bidder.

When talk turned to weed at the tail end of last night's three-hour Republican primary debate, the candidates delivered some of the most spirited exchanges of the evening.

Rand Paul, the libertarian-leaning senator from Kentucky who has long championed cannabis legalization, wasted no time in calling out what he described as the hypocrisy of enforcing laws against marijuana. In doing so, he also put the heat on Jeb Bush, calling out the former Florida governor on his pot-smoking days in high school.

Legal marijuana commerce - to some extent a reality in 24 states and the District of Columbia - may be the fastest growing industry in the United States. Regardless of what we think about pot use, these facts beg the question: if voters continue to push for legalization, what is the best way to end prohibition of a popular business activity?

I thought Republicans supported reason and free enterprise, and yet here's Steve Schuh, the Republican executive of Anne Arundel County, getting his socks in a knot about the prospect of someone growing, processing and dispensing marijuana for medical purposes along the banks of the Severn. He wants to ban in his county what a new state law allows. Schuh worries that people who get therapeutic cannabis might end up becoming dealers.

Senator Rand Paul talks about how marijuana legalization should be protected by states like Colorado and Washington. Paul has always defended letting the states legalize marijuana and that incarcerating people for consuming weed has been a disaster and needs to change. Paul stood out on the Republican stage as the only candidate to defend marijuana and states' rights.

In early 2015, Denver officials cited a handful of commercial marijuana growers for misusing pesticides in indoor grow houses. Some of those businesses were also advertising their products as “chemical-free” and “organic.”

Because the drug is still illegal at the federal level, and state regulators are still playing catch up, growers can make all kinds of unchecked claims about their plants, without drawing the ire of consumer fraud regulators. That could soon change.

The US has again "decertified" Bolivia over what it calls a failure to comply with international narcotics agreements, despite recent data showing the country has achieved an unparalleled decrease in coca cultivation compared to other Andean nations in South America.

The decision, while widely expected, was roundly criticized by drug policy experts, who called the move hypocritical given that the US may be in contravention of UN drug conventions due to legalized marijuana markets in several states.
