I don't smoke on a regular basis, but when I do it occasionally, it doesn't matter what the packaging looks like. If anything, I think it promotes more smoking because there's no pressure of what brand cigarette you smoke.
I think it's a common misconception that people who smoke are unaware of the side-effects - I mean, it tastes horrible, and yet it can quickly escalate to become a dangerous habit. But it also feels good, like any other drug that you've tried before and think it gives you a 'high' of some sort.
The packaging isn't what sells the cigarettes - it's the cigarettes themselves. One smokes the cancer stick, not the package, so it's quite redundant if you ask me.
