What a bunch of hogwash. Just goes to show that there are "expert" studies that can support anything. Taxes on cigarettes went up and up and up for decades with little or no effect - and that was on a product that could clearly kill you!. It wasn't until the taxes hit huge levels that they started to take effect - when people could simply no longer afford them. All that said, Jamie must be a Liberal - "grooming" the sheeple for another tax grab.
