Investing in the top marijuana penny stocks on the market can be an exciting way to grow your portfolio. They give investors an affordable entry point into one of the hottest markets in the United States.

In fact, the top marijuana penny stocks to watch in February 2019 can bring gains as high as 300%.

Local and federal governments have been legalizing cannabis more and more over the past year. That's only going to increase the size of markets and the amount of demand. Let's look at all the milestones. In mid-October 2018, Canada legalized pot all across the country. In late October, the incoming Mexican government said it would take steps to legalize cannabis.

It’s been a little over 3 months since Canada legalized recreational marijuana and the results from the National Cannabis Survey finally came in.

More than half (55%) of Canadians aged 15 and older indicated that they have never used cannabis, while 3 in 10 were former users who reported no longer using it.

Results say that about 4.6 million of Canadians aged 15 and older reportedly used cannabis in the last three months of 2018. This accounts for roughly 15% of the total population.

Medical users are more established

Consumption rates also continued to be higher among males (19%) than females (11%)—consistent with data from previous quarters.

The past two sessions have featured an interesting pullback in shares of Supreme Cannabis Company Inc (OTCMKTS:SPRWF). This has been one of the most notable comeback stories in the Canadian cannabis patch thus far in 2018, with the stock as much as doubling since late December on strong volume. We have been fans of the story over that time, would suggest traders and investors keeping a close eye on the action in case we see a confluence support test of both the 50-day and 200-day moving averages, which could align in the $1.35 area if the stock dips a little bit further.

Biome Grow Inc (CSE:BIO) (OTCQB:BIOIF) announced Tuesday that it has entered into a Memorandum of Understanding (MoU) with CBD Acres Manufacturer Inc providing Biome with preferential access to a high-quality, low-cost supply of Cannabidiol (CBD) concentrate.

The agreement is for a five-year period and positions CBD Acres as the supplier for Biome Grow with a commitment of up to 20,000 kg per year of locally sun-grown, hemp-based CBD extract using the company’s Nano lipid, solventless extraction process. CBD Acres extraction process is void of any harmful chemical solvents.

2019 has been quite the year for Canada’s leading marijuana stocks. So far, at least. There’s still a lot of time left.

Canopy Growth Corp (TSX:WEED)(NYSE:CGC) is a prime example. Shares ended 2018 on a severe down note, falling from a high of $76 each all the way down to $36. That’s more than a 50% drop from when marijuana was officially legalized to the end of the year, the exact time Canopy Growth shares were expected to soar into the stratosphere. But that’s nothing but a distant memory, at least for folks who held on. Canopy shares are up more than 64% thus far in 2019, and that’s even after a bit of a pullback in the last week.

A report going to the city’s intergovernmental affairs committee Thursday recommends the city use a public consultation period on edibles regulation to press for more funds from Ottawa and the province to cover a forecast $6.6-million shortfall in dealing with local cannabis issues.

While the province has given the city $3.84 million to help cover enforcement and regulation costs through 2019, city officials say they expect those expenses to reach $10.44 million by the end of this year.

“We’re picking up the tab for the provincial government at a time when we’re facing an economic downturn,” said committee member Coun. George Chahal.

The Quebec government faced strong opposition as public consultations began Tuesday on its bill seeking to increase the legal age of cannabis consumption and ban it from all public areas.

Junior Health Minister Lionel Carmant has said he tabled Bill 2 in order to protect young people and send a message that smoking marijuana is not a trivial matter. The proposed legislation restricts marijuana usage to people aged 21 and over and limits its smoking to private property.

You probably hear a lot about the biggest marijuana stocks that are sizzling hot right now.

But several other marijuana stocks are also performing really well so far in 2019, including The Green Organic Dutchman (NASDAQOTH:TGODF) and Green Thumb Industries (NASDAQOTH:GTBIF).

The Green Organic Dutchman is up nearly 40% year to date, while Green Thumb Industries stock has soared over 50%. Which of these two lesser-known but high-flying marijuana stocks is the better pick for investors?

While one can’t necessarily overdose on cannabis, there have been instances where potent edibles have resulted in hospital visits, Gizmodo is reporting. A new study published in the Canadian Journal of Cardiology detailed the story one 70-year-old man who used a THC-infused lollipop to get to sleep and ended up having a heart attack. It should be noted that this man did have a pre-existing heart condition — coronary artery disease, a condition where the buildup of plaque in arteries narrows blood flow to the heart. Still, the man hadn’t had a flare-up for the past two years and was regularly taking his medication.

Constellation Brands (NYSE:STZ) wasn't always a household name among investors. Even with high-profile holdings in the beer and spirits world, including brands like Corona and Modelo, Constellation largely took a back seat to other players in the alcohol industry.
