Do you feel like you’ve missed out on the massive gains reaped by early investors in Canada’s marijuana stocks? With marijuana stocks tanking in tandem over the past few months, is it time for wary investors to jump in?

Up until the last few months, cannabis stocks had been on a tear. Cronos Group, for example, rewarded its early investors with a gain of 1,200% over the past two years, until the downturn began.

If you’d been smart or lucky enough to have been an early investor in Canopy Growth, the results would have been even more impressive. You would have seen your investment grow 3,250% before the pullback.

For years, cannabis stocks have been showing investors the green. Early investors in some of the most popular pot stocks are likely sitting on triple-digit or quadruple-digit gains today, with more than a dozen cannabis stocks gaining at least 70% during the first quarter.

However, the green rush has come to a crashing halt since April began. Few cannabis stocks are near their 2019 highs, with most registering double-digit losses during the month of July.

Ontario will triple its pot-store count beginning in October, just two months before the introduction of new product formats that are expected to significantly boost sales in Canada’s most-populous province.

While chatter about the next wave of legalization in Canada tends to focus on products like edibles and beverages, many of the biggest players entering the space say consumers will opt for the more conventional format of vapes.

Thanks to some quirky regulations, there are some odd realities for cannabis stocks . For example, Canadian cannabis producerAphria (NYSE: APHA) is listed on the New York Stock Exchange (NYSE) while U.S. cannabis operator Green Thumb Industries(OTC: GTBIF) is listed on the Canadian Securities Exchange (CSE) and is available in the U.S. only on an over-the-counter market.

Because it doesn't have as much visibility, some investors could be overlooking Green Thumb Industries. But is it a better cannabis stock to buy right than Aphria? Here's how the two stocks stack up against each other.

Shares of water resource specialist Cadiz (NASDAQ: CDZI) have jumped 19.5% this month through Aug. 23, while the S&P 500 , including dividends, is down 4.3%. That brings the stock's 2019 gain to 25.5%, versus the broader market's 15.1% return.

The catalyst for Cadiz stock's August pop was the company's announcement that it has entered the U.S. hemp market. Hempis a strain of cannabis that contains a negligible concentration of tetrahydrocannabinol (THC), the psychoactive substance responsible for giving marijuana users a "high."

Here's what you should know.

Management’s strategic choices at the outset of a new business venture can significantly influence future financial successes or failures, and it’s encouraging to see executives at a cannabis growth stock like Aphria (TSX:APHA)(NYSE:APHA) quickly learning from and correcting a seemingly early mistake made in 2018 to give the company a new market access.

KushCo Holdings (OTC:KSHB) is the latest marijuana stock to announce a round of fresh borrowings. The company, which focuses on the supplies and packaging used to consume cannabis, said it secured a $50 million credit facility, to be provided by Monroe Capital, a credit asset management company.

The facility consists of a $35 million revolving credit line, plus a $15 million accordion (i.e., the right for the borrower to expand the facility if need be). Its availability is contingent on "covenant compliance and borrowing base ability," KushCo said.

Canadian consumers don't have to wait until mid-December to legally consume some cannabis-infused gummies — if they're willing to make some themselves.

For those who may be wary or intimidated by cannabis cooking, Victoria-based company Paracanna has developed a do-it-yourself kit to which consumers can add drops of legally procured oil to create gummies in flavours such as "punchy pink grapefruit."

The kits, called Zen Zingers, allow people to control the cannabinoid dosage and make gummies at a lower price at home in about 10 minutes, said Paracanna chief executive Andrea Butterworth.

Small cannabis companies -- and some that aren't so small -- don't have a lot of avenues for raising capital. That's especially true in the U.S., where federal laws place tight restrictions on financial institutions' ability to do business in the cannabis industry.

Canopy Rivers (OTC: CNPOF) and Innovative Industrial Properties (NYSE: IIPR) provide alternatives for cash-strapped cannabis companies. Investors have rewarded Innovative Industrial Properties more for its efforts, with the stock soaring more than 120% year to date while Canopy Rivers shares have dropped over 20%. But which of these two cannabis stocks is the better pick looking ahead?

Investors aren’t buying the growth story of cannabis stocks anymore. They are getting impatient and want to see a clear path to profitability now.

The reflection of this thinking can be seen in the stock prices of top marijuana producers that are plunging — and not showing any sign of bottoming out.

Canopy Growth Corp. (TSX:WEED)(NYSE:CGC) and Tilray Inc.(NASDAQ:TLRY) are the two big victims of this bloodbath in marijuana stocks, as these companies have yet to show a clear path to profitability.
