No, I'm afraid it is still cool to smoke. I have a daughter and four nieces over 18. All are achingly cool. All smoke. All of them took up smoking in the period when these images were on packets. None of them cares about the pictures because young people don't think they'll ever die and so don't think such things apply to them.
Of course it's cool to smoke. There is literally no other reason to do it.
And no. Governments like putting the pictures on packets because it appeases authoritarian. finger-wagging nanny state types like you and makes it look like they're doing something. If you seriously believe government and its agencies only keep doing things because they work, you seriously haven;'t been paying attention.
Do try and think it through, p. Why would they even try it if it didn't have any social cachet - let alone go back to it? I can assure you it's not the taste.
You may not realise this, but you don't instantly get addicted to cigarettes. It takes effort. You have to go through a few weeks of doing something actively unpleasant before it becomes enjoyable (ie an addiction). Why on earth would you do that if there weren't other social factors at work?
Of course smoking is cool. The fact that most people aren't cool and so don't smoke does not disprove this.
