Gallup has been tracking support for legalization since 1969 when it was at just 12 percent. The latest poll shows support currently matches the 2013 high of 58 percent.

Not surprisingly, the greatest support for legalization falls to younger generations, but some of the greatest gains are in the 35-49 year old age range.

And not only is the support for legal cannabis increasing, CBS News reports actual usage among adults in America has doubled. Since 2001/2002 use has risen from 4.1% to 9.5%.
