"Overall public opinion of marijuana has changed," said Dan Humiston, president of the International Cannabis Association. "The stance has just softened. With time as the population ages, a lot of the generations that were really opposed to it are being replaced with the generations that are comfortable with it."
Bloomberg reports that the cannabis industry had a market capitalization of $3 billion as of April. There's currently more than 50 publicly traded pot-related companies. Twenty-four states have legalized medical marijuana, and recreational use for adults has been approved in Washington, Colorado, Alaska, Oregon and Washington, D.C.
