"U.S. retail cannabis sales will rise more than five-fold over the next five years, from an estimated $2.2-$2.6 billion in 2014 to $7.4-8.2 billion in 2018, according to new financial data released today in the 2014 edition of the Marijuana Business Factbook."
"The U.S. black market is currently estimated to be in the $40 billion range. Thus, the legal marketplace has significant potential beyond 2018."
“If you take the whole industry, not just medical but the entire marijuana market in the U.S., you’re probably looking at $40 billion. Some estimates have it as high as $100 or $120 billion,” said founder and CEO of Weedmaps, Justin Hartfield. “If you compare it to the wine industry, which is maybe $10 or $20 billion, it’s at least that size and probably much larger.”
