The countdown is on.

In just 10 days, the global cannabis industry will be dramatically reshaped. On Oct. 17, Canada opens the market for the legal adult use of recreational marijuana.

The impact from the first major economic power to allow recreational marijuana on a nationwide level will be enormous.

Dozens of companies that have previously supplied only medical cannabis in Canada anticipate a surge in revenue.

Medical marijuana producer Sun Pharm Investments Ltd. is moving to create Zenabis Global Inc., a publicly-traded company with growing operations in British Columbia, New Brunswick, and eventually in Nova Scotia.

The privately-held cannabis company is merging with a subsidiary of propagated agricultural plants supplier Bevo Agro Inc. via reverse takeover, in which a smaller firm takes over a public company.

Just upriver from downtown Montreal, the Kahnawake First Nation council office takes pride of place in the reserve’s modest skyline, along with a youth centre and a pair of churches.

Soon, however, these old edifices may all be dwarfed by a sprawling, state-of-the-art greenhouse sprouting with cannabis plants and buzzing with cultivators of Canada’s newest legal commodity.

The Mohawk Council of Kahnawake has signed a non-binding agreement with Canopy Growth Corp. The potential deal would see the First Nation host a 4,650-square-metre production facility, plus a processing and packaging space nearly half that size, in partnership with Canada’s largest cannabis company.

Pot stocks are extremely expensive, and most investors know this. The question is: just how expensive and/or valuable are these securities?

In an attempt to conquer my thirst for curiosity with respect to marijuana stocks, I decided to dive into just how valuable these companies are relative to the entire Toronto Stock Exchange. The numbers are staggering.

Below is a chart of Canada’s top nine marijuana producers by market capitalization (as of time of writing):

You've probably heard Tilray (NASDAQ:TLRY) mentioned or read about the stock more times than you can keep track of over the last few weeks.

The marijuana stock's phenomenal rise, fall, and rebound have certainly attracted plenty of attention. 

Tilray's performance has made Auxly Cannabis Group's (NASDAQOTH:CBWTF) year-to-date gain of around 25% seem puny in comparison. Auxly definitely hasn't gotten even a fraction of the hype that Tilray has.

But which is the better marijuana stock now? Here's a quick look at how Tilray and Auxly stack up against each other. 

Cannabis stocks have been on the rise this year ranking among the best portfolios so far. This comes as Canada legalized the use of recreational marijuanawhile more states within the U.S are following the same path. Grow Tech Labs, a subsidiary of the Victory Square Technologies that was formed to accelerate the innovations within the Cannabis industry, recently collaborated with Launch Academy enhance efficiency.

With marijuana legalization just around the corner, it's no secret that there's going to be a massive spike in usage across Canada. 

Because of this, law enforcement as well as the Canadian military want to make sure all of the effects of being high are known and can be put to the test to see how impaired a person really becomes.

That's why they just spent $35,000 on "weed goggles."

Canadian investors who missed the rally in marijuana stocks over the past two years are wondering which cannabis companies are the best stocks to buy.

Let’s take a look at Canopy Growth (TSX:WEED)(NYSE:WEED) to see if the stock is priced right to add to your portfolio today.

Early consolidation

Canopy Growth quickly emerged as the leader in the Canadian cannabis space and is positioned to be a major player on the world stage.

The billion-dollar beverage giants have set their eyes on an entirely new industry, an industry that they fear will soon swallow them up if they don’t get ahead of it.

So, if you think you missed the cannabis boom…. Now may be the time for you to get in.

In a matter of days, Canada will legalize recreational marijuana—and it will be the staging ground for other parts of the world.

The highest estimates have global legal cannabis sales reaching nearly $146 billion by 2025. With recreational pot in Canada, the legal recreational sales bonanza is beginning.

Michael Serruya has never used cannabis. “But I am anxiously awaiting October 17,” says the managing director of Serruya Private Equity, referring to the date on which Canadians can legally consume the plant. “I think there are a lot of people like me out there.” It’s more than an idle observation: He’s deeply invested in the cannabis sector.
