That may be the case, but think about how you get your tobacco. Tobacco would be affected as well.
Perhaps more salient would be how do you get your papers. No more Zigzag to be found!
I suspect there would still be a fair bit of tobacco gone wild and to seed not too far off in Virginia, but would you really want to twist it up in a page from an old moldy book?
I'm guessing that most folk would use pipes, as they did in the old days.
In any case, there are decent (non anti-smoking fanatic ones) reasons for getting rid of all the boxed and pre-rolled cigarettes, and thanks to Justinother, it seems we now have the means also!
