KUSA–A survey of Coloradans found that approximately one in five adults in the state have used marijuana since legal recreational sales began on Jan. 1, 2014.
Nineteen percent of Coloradans reported using the drug post-legalization according to a public opinion poll published by Quinnipiac University.
The number is higher than the 15 percent of Coloradans who told the same pollsters in August of 2013 that they planned to try pot once recreational sales began.
