Cannabis stocks had a case of the Mondays and declined steeply in a rough start to the week, with broad drops across North American markets. The North American Marijuana Index, which tracks the top cannabis stocks in the US and Canada, was down 4.2% to 268.6 points by Monday midday. The Horizons Marijuana Life Sciences Index ETF was down 4% at C$19.50.

The CSA Group is currently working on a new standard to address cannabis impairment in the workplace, which is scheduled to be released spring 2020, attendees heard at the Partners in Prevention Health and Safety Conference and Trade Show in Mississauga, Ont. on April 30.

Just over six months have passed since cannabis has been legalized in Canada, and there remains limited regulatory guidance or legislative directives for employers and safety professionals to manage the effects of the substance in the workplace, especially in safety sensitive positions. The standard will aim to bridge this knowledge gap.

HEXO Corp (NYSE:HEXO)(TSX:HEXO) is one of the best performing marijuana companies on the stock market in 2019. Its performance—so good, that HEXO stock has already doubled since the beginning of the year. This is the result of revenue reports that reflected year-over-year growth of 1,269%. A sales increase of 144% from the previous quarter, also helped.

Following a move into Jamaica with a retail storefront opening, Canadian company The Green Organic Dutchman Holdings (TSX: TGOD; US: TGODF) announced another international expansion by entering the German CBD market. 

The expansion is taking place through The Green Organic Dutchman’s (TGOD) subsidiary HemPoland, which was just granted organic certification for European markets in late April. 

Tilray Inc (NASDAQ:TLRY) was one of the stars of last year’s marijuana madness. During the rally kicked off by Canopy Growth Corp’s (TSX:WEED)(NYSE:CGC) $5 billion acquisition, Tilray actually briefly eclipsed Canopy itself, going on a 750% rally that sent its market cap to unprecedented levels. At the time, there was a lot of hype surrounding the company, a recent IPO that had the blessing of some high-profile Silicon Valley venture capitalists.

Last year, the marijuana industry broke down more than a dozen barriers. We witnessed an industrialized country legalize recreational pot, saw the U.S. Food and Drug Administration approve the very first cannabis-derived drug, and watched as numerous marijuana stocks uplisted from the over-the-counter exchange to either the New York Stock Exchange or Nasdaq.

But after a year of promises, 2019 and beyond will feature a new focus. With the industry blossoming under the umbrella of legalization through much of North America and Europe, it's now up to pot stocks to deliver the green. In other words, operating results actually matter now.

Village Farms International (TSX:VFF)(NASDAQ:VFF) has been one of the best performing pot stocks since the beginning of the year. Equity markets have been on fire, and many marijuana companies are performing well, but Village Farms’ year-to-date 200% jump in share value dwarfs that of most of its peers.

As a result, the marijuana company has been getting an increasing amount of attention among investors trying to pounce on the growing cannabis market. Is Village Farms’ recent performance a fluke? Or is the firm a good buy at the moment?

The much-maligned Aphria Inc. (TSX:APHA)(NYSE:APHA) is notably beating the odds of late. This $2.3 billion producer and seller of medical cannabis almost got delisted from the TSX two years ago on allegations of non-compliance to listing requirements. Short selling issues also hounded the Leamington-based firm.

However, the dust has settled and Aphria remains on the big board, both in Canada and the U.S. Now that the turbulence is over, the excitement is back. Investors are taking Aphria more seriously this time. The growth potential is there given the positive developments happening in the present.

Philip Bennett could soon be homeless.

The 57-year-old is getting kicked out of his apartment building because he smoked and vaped medical marijuana on his balcony. 

He uses the marijuana to treat the pain caused by a genetic disorder that's slowly destroying his body. It has already robbed him of his ability to walk long distances.

Outside of his apartment, Bennett requires a motorized wheelchair to get around. 

Bennett's landlord wants him out of the apartment building in Dartmouth by May 1, saying that Bennett broke the building's ban on marijuana use and that his smoking caused another tenant to move out.

That's led to a legal fight that questions what right a landlord has to decide the kind of medication a tenant can use.
