In case you haven't noticed, the cannabis industry is growing at an incredible pace.
Within the U.S., according to a report from Marijuana Business Daily released in 2017, legal weed sales are expected to grow by 45% in 2018, mainly because California opened its doors to legalized recreational weed.
Throughout North America, cannabis research firm ArcView estimates the industry can grow by an average of 26% annually through 2021. That type of growth is hard for investors to ignore, and it's a big reason many pot stocks have doubled or tripled in value over the trailing year.
But as you're probably aware, even with marijuana being viewed in a more positive light in the U.S. and many other countries around the world, the industry is completely different from one country to the next. This is perhaps no more apparent than when examining the price per gram for cannabis across the world.
