These Canadian Marijuana Stocks Have Grown Sales by More Than 1,200% Since 2015

There's a very good reason the legal marijuana industry has been referred to as the "green rush" -- it's making marijuana-stock investors a lot of money. Far more pot stocks than not have had their valuations double or triple over the past year.

The catalysts behind this bullishness are a combination of legal sales growth potential, and a consistent shift in the way the public thinks about cannabis.

In terms of sales, cannabis research firm ArcView is forecasting a compound annual growth rate for North America of 26% through 2021. If this comes to fruition, we'd be talking about a nearly $22 billion market by 2021, up from $6.9 billion in 2016. Considering that an estimated $46.4 billion in sales were still conducted on the black market last year, there's a lot of opportunity for legal expansion throughout North America.
