Canada can’t keep up with demand for newly legal weed. Four days after the country put marijuana legalization into effect nationally, retail shops are nearly sold out.

“It’s a mess. The supply is just a mess,” Patrick Wallace, owner of the Alberta shop Waldo’s 420 Store, told CBC.

Canada’s Parliament voted to legalize marijuana in June, and that decision went into effect on Wednesday, with differing rules across Canada’s provinces. The newly legal industry is expected to be worth $6.5 billion in annual sales.

Wednesday marked the "big day" that every cannabisand marijuana stocks enthusiast has been waiting for. The country firmly moved ahead with its program that legalizes the sale of recreationalmarijuana across Canada. As government cannabis retailers opened from Newfoundland to British Columbia, Canadian citizens battled long lines and waited for hours to buy the first state-approved cannabis.

Today we have identified some Canadian marijuana stocks that are well positioned to meet Canadian recreational cannabis demand for the foreseeable future.

Statistics Canada estimates that Canadians spent $5.7B on cannabis in 2017 and the demand for cannabis is expected to be extremely high now that it can be purchased legally. To meet such demands many Licensed Producers in Canada have made significant investments to increase their production capacity by renovating or building production facilities.

Ontario and B.C. alone have already snapped up more than half of the country’s existing grow-op space.

The rush for cannabis is on in Canada and so is finding the real estate to grow it.

The legalization of recreational weed on Wednesday has already fuelled a sixfold surge in pot-growing facilities to 8.7 million square feet (808,256 square meters) in the year through September, according to data from Altus Group Ltd. — space about the size of Amazon.com Inc.’s Seattle headquarters.

If you feel confused about the rules for using, buying, growing or doing anything with cannabis, you are not alone.

For starters, know this: the federal law, The Cannabis Act, lays the framework, but the provinces and municipalities ultimately set the ground rules. With that said, here’s are a few kind-of-confusing-cannabis laws that might trip you up, but could cost set you back thousands if you don’t remember.

Canopy Growth (TSX:WEED)(NYSE:CGC) was down 6.85%, Aurora Cannabis (TSX:ACB) was down 7.23%, and Aphria (TSX:APH) was down 6.08% on the day before legalization.

At the time of writing, it is the day of legalization — the day this massive market is officially opened and when the sale of marijuana begins to be taken away from the black market.

As a reflection of the volatility and the risk that is still inherent in marijuana stocks, let’s look at what is happening in the market.

As the high from Wednesday’s historic cannabis legalization wears off, there are a few legal footnotes worth taking note of before lighting up again.Despite being allowed to use or even grow marijuana, Canadians can still be charged if they’re caught breaking a number of important laws accompanying legalization.

CTVNews.ca has rounded up 10 actions that will still be considered crimes now that cannabis has been given the green light.

Popular marijuana stocks fell across the board Wednesday, paring extreme gains so far this year, as investors cashed in a bit of their bet as Canada became the largest country to legalize the recreational use of cannabis.

After months of political haggling and legal debate, Canada joined the U.S. states of California, Massachusetts, Maine, Alaska, Colorado, Washington, Nevada, Vermont and Oregon as the first Group of Seven country to OK adult use of pot. The major cannabis stocks ran up in anticipation of this day and offered investors on Wednesday a reminder of just how volatile some of the young pot companies have become amid a flurry of news and speculation.

Marijuana stocks were under pressure early Wednesday after Canada become the second country to officially legalize marijuana.
