The business of marijuana is on fire.

It's a $50 billion dollar black market business, according to Hadley Ford, CEO of iAnthus Capital Management, a company that provides funding for cannabis cultivators. The company is publicly traded on the over the counter markets and since its debut in September 2016, shares are up some 75%.

"There's no financing available for people in the market," he said, adding that 28 states have legalized medical marijuana, while eight states have legalized recreational marijuana.
