I'm a big a fan of PA as the next guy. It's my go-to when I'm working outside on the farm or grabbing a "quick" smoke throughout the day. But it occurred to me: is PA actual tobacco leaf? Or is it "sheet tobacco" like most cigarettes today - ground up stems, etc, pressed into a sheet and chemically treated prior to being shredded not ribbons? For that matter, is all OTC tobacco actually just "sheet tobacco"?
