Bingo. When I smoked cigs, I'd end up smoking half as many if I had access to a really strong brand e.g. Marlboro Reds or Newports. Likewise, I'd go through a pack of light cigarettes twice as fast. It wasn't conscious - my brain wanted its set dose of nicotine.

When I did quit eventually with nicotine gum, I gradually lowered the dose over the course or a month or two, but it was a very conscious process, and I absolutely had to discipline myself to push through the cravings.

All this will accomplish is forcing mostly poorer people to purchase more cigarettes than they currently do in order to get the same fix they're accustomed to.
