As a long-time tech-investing analyst, I have one of the best vantage points in the country for tracking profitable marijuana industry trends.
Here's the thing: I live 10 minutes from the epicenter of the medical marijuana movement in northern California, and the rest of the nation for that matter.
Downtown Oakland contains a small cannabis-friendly district known as "Oaksterdam." In fact, there's a patient co-op across the street from a store where I buy my fedoras.
I bring all this up so you know I've followed what's been happening with the marijuana legalization movement for years.
In these parts, it's difficult to avoid - you see lots of folks walking around wearing their official Oaksterdam t-shirts.
Since California legalized medical marijuana in 1996, another 19 states have joined the movement.
The San Francisco-based market research firm ArcView Group estimates the national legal marijuana market at $1.53 billion in 2013. ArcView expects sales to nearly double to $2.57 billion by the end of this year.
