(CNN) I see signs of a revolution everywhere.
I see it in the op-ed pages of the newspapers, and on the state ballots in nearly half the country. I see it in politicians who once preferred to play it safe with this explosive issue but are now willing to stake their political futures on it. I see the revolution in the eyes of sterling scientists, previously reluctant to dip a toe into this heavily stigmatized world, who are diving in head first. I see it in the new surgeon general who cites data showing just how helpful it can be.
I see a revolution in the attitudes of everyday Americans. For the first time a majority, 53%, favor its legalization, with 77% supporting it for medical purposes.
