Medical marijuana in Pennsylvania

It's not as exciting or advanced as in New Hampshire, Rhode Island or Vermont, but at least a medical marijuana bill has been introduced in Pennslyvania. Near as I can tell, it will be a while before legislative opinion settles or coalesces. If MM does get substantial support in PA, especially in rural PA, that could be an indicator of increasing acceptance in what might roughly be called "heartland" areas. If in rural Pennsylvania, why not in most of the Midwest? Illinois is on the way, though success is not guaranteed this time around.,
