You think that high driving started with the legalization of pot in a few states? Really?
I think legalizing pot attracts users from all over the fruited plain to move to that state and numerically compound the problem.
I know somebody who works with the homeless in Denver. If you think I am wrong he would beg to differ with you. As would the GOP electoral vote counters who advise all of those candidates not to come out against Colorado legalization.
