One aspect of marijuana's legalization that isn't up for debate is demand, as a recent report says adult pot sales in the U.S. were up 184 percent in 2015.

According to marijuana investment group ArcView and financial data firm New Frontier, America's legal recreational marijuana industry sold $998 million in 2015, up 184 percent from $351 million in 2014. Despite little to no access to banking services because of the plant's federally illegal status, ArcView estimates that the legal pot market is worth $5.4 billion and that its value will grow to $21.8 billion by 2020.

“Many in the business and financial sector have taken a ‘wait and see’ approach to the legal cannabis industry," ArcView CEO Troy Dayton says in a statement. "The new data confirms what pioneer investors and entrepreneurs suspected. Legalization of cannabis is one of the greatest business opportunities of our time, and it’s still early enough to see huge growth.”

Part of ArcView's annual State of Legal Marijuana Markets report, the study lists congressional action, the upcoming presidential election, compliance and regulation, price wars and energy use as critical trends that will shape the marijuana industry's future.

"With nearly a dozen states debating changes to their cannabis laws in the coming year, 2016 will be the tipping point in which a majority of U.S. states transition from cannabis prohibition to some form of regulated legal market,” notes New Frontier CEO Giadha DeCarcer in a statement of her own.

Seven states — Arizona, California, Maine, Nevada, Massachusetts, Rhode Island and Vermont — are expected to vote on recreational legalization in 2016. In addition, Florida, Ohio, Missouri and Pennsylvania are likely to decide on advancements in medical-use laws as well.

Four states and Washington, D.C., have legalized cannabis recreationally, along with 23 that permit some form of medical use. Colorado, the first state to allow adult-use marijuana sales, reported nearly $700 million of legal pot sales in 2014. Washington, the second state to legalize recreational marijuana sales, reported $257 million in sales after its first year. Alaska and Oregon permitted legalized adult use in 2015, but Oregon started adult sales in October, and Alaska has yet to start its regulated system.

According to the Colorado Department of Revenue, the total revenue from recreational marijuana taxes, licenses and fees was more than $100 million in 2015.
