I think this is a pretty nifty idea. This will stop all those would-be smokers that attempt to do it look. Because honestly, after seeing that, I hate cigarettes EVEN MORE. My mom, dad, both my grandmas, cousins, aunts, and uncles all smoke. A lot of people that I hang out with smoke.
Thing is? They hate it. They wish that they never even started. They think they are most disgusting thing in the world, and their advice is always: Don't start smoking. I haven't met anyone who has pressured someone into smoking cigarettes, they always tell the opposite actually. Those who smoke, only say that they do it because they are so far down the road and addicted, that quitting is hard. They all have tried and failed at one point. Either because 1) they aren't committed enough or 2) they are still in a cigarette heavy environment . But also, maybe when they go to reach for their pack, this will remind them not to, or at least make them think about it. It could work, honestly.
But like other people have said, this isn't so much a tool employed to help people quit, as it a tool employed to sop people from starting. Sometimes the best cure is prevention, stop it before it even starts, and then you don't even have a problem.
But.. smoking does stay constant... because there is honestly too much tobacco in this world. I know people who have quit for years, and after being around the stuff for so long have started to gain cravings for it and the desire to smoke again. Solution: Cut tobacco down. Problem: Higher unemployment.
This reaches a bit of a impasse there.
