Unlike its southern neighbor, Canada legalized medical marijuana nationwide back in 2001. That means that the industry has evolved a lot more and is not plagued with restrictions across state lines, as is the case in the United States, where there are about 28 states where pot is allowed for medical use. Further, a task force commissioned by the Canadian government came out with a report in November 2016 with recommendations for changing the current regulations and paving the way for legalization of pot for recreational purposes as well. In the United States, currently only eight states have legalized marijuana for recreational use.

While uncertainty prevails in the United States, investors could get a piece of the pot action by investing in Canadian stocks traded in the country in the over-the-counter (OTC) markets. Most of these stocks can be labeled as penny stocks, so any investment may carry a significantly higher risk component. Here's a look at some of those companies.

1. Canopy Growth Corp.

Market Cap: $2.94 billion

With its market cap exceeding a billion dollars, Canopy (OTC: TWMJF) is touted as Canada’s first unicorn in the pot market. While the company sells its produce under various brand names, the brand ‘Tweed’ has had the most recognition, thanks to its affiliation with rapper Snoop Dogg. The one-year return for the stock in the OTC market has been 150.57% as of November 8, 2017.

2. Aurora Cannabis

Market Cap: $1.23 billion

Aurora Cannabis (OTC: ACBFF) debuted on the Canadian venture stock exchange (TSX) in October 2016.

5. OrganiGram Holdings

This company's portfolio includes dry cannabis and cannabis oil, along with accessories like vaporizers that can be purchased on its website. Although it promises organic produce, OrganiPharma (OTC: OGRMF) issued a product recall in December 2016 because the products contained pesticides not approved for marijuana growing. As of November 8, 2017 the stock has a return of 29.79% for the one-year period.

A big boost for THC BioMed (OTC: THCBF) came in December 2016, when it got the green light from the authorities to start shipping marijuana plants for licensed growers across the country.
