If you've got the money and can afford to smoke, as well as enjoy it, then go ahead and smoke.
If you haven't got the money, or could put it to better use, then stop.
It really is that simple.
Well, it's bastard hard actually, but all you have to do is to just not light up. Be honest with yourselves, if you'd actually like to quit then try, don't then justify the waste of money that these e-cigs are by saying it's better for you. Yeah it is, but you still look f'ing daft standing there with one hanging out of your mouth.
Go on, honestly, who here would actually quite like to not smoke and have the money instead?
