I believe that Amtrak, being some sort of "Federal property," prohibits the use of weed on its trains (and probably in the stations, too) even in the states where it's legal. I suppose this would also prohibit the use of edibles and other forms that aren't smoked. I'm fine with people using weed (as long as they're not driving while stoned), but I agree that the reek of weed is even worse than that of tobacco. I think it's the new varieties, as I don't remember the smell of pot being that vile back when I was in college. Or maybe it was masked by the pervasive smell of tobacco smoke back then Come to think of it, I'm surprised that my lungs are functional now after all that secondhand smoke.If smoking were allowed, wouldn't smoking marijuana have to be permitted when trains pass through states that allow marijuana? Marijuana has a vile smell, far worse than cigarette tobacco.
