Venture capitalists and private equity funds are having no problem raising money for cannabis-related enterprises. : As more states voted to legalize some form of marijuana, the biggest being California and Colorado to date, pot sales have gone through the roof. An ArcView market research pegged 2016 sales for legal weed at $6.7 billion, a whopping 34% jump over the previous year. And this trend is unlikely to slow down. In 2018, that figure grew to $10.4 billion in sales. And that’s where investors smell a dank opportunity.
