Yep more people just need to be more voval about pot use.Bring it up every chance you can.Let people know you do it from time to time or you use to do it and see nothing wrong.Before long everbody smokes or knows somebody who smokes and they see whta a non-issue smoking is and eventually when an intiative or a pro candidate comes on the ballot they'll vote for it.
Word of mouth.It works.
