Sounds like an excellent idea, but I have my doubts about its effectiveness.
My stepfather got a couple packs of Canadian cigarettes a few years ago, and was very amused at the warning graphic. It hasn’t stopped him from smoking though, and I’ve never known anyone who it has stopped. Everyone seems to think that it won’t happen to them. Hate to tell you this people, but it can and it probably will. Stop while you’ve got the chance.
