With 30 states and the District of Columbia having legalized medical cannabis in some form, it's clear where to find the top marijuana penny stocks...
The medical marijuana sector.
In the long term, Money Morning believes the cannabis industry is too big to stop. California just legalized recreational marijuana sales in January, and other states across the country can use California as a roadmap for their own legalization.
Legal cannabis sales in North America are expected to climb from $10 billion in 2017 to $24.5 billion in 2021, according to Arcview Market Research.
That's a 145% sales increase in just two years.
But right now, recreational marijuana is only legal in in eight states.
Meanwhile, medical cannabis is legal in nearly 70% of the country already.
That's why today, we wanted to share all the details with Money Morning readers about three of the top penny pot stocks to buy now.
The first cannabis pot stock on this list has climbed from $0.39 to $0.64 over the last 12 months - a 64% jump.
And if the stock price keeps that kind of momentum, it could climb another 64% over the next year...
