What, the fact that you're so weak that you have to give in to the temptations of smoking like the filthy mongrel you are? :p
Tried most shit that I could ever try and none of it was able to stick with me, so it's not your primal instincts forcing you to do it - it's your shitty routine system, and don't tell me you can't quit whenever you want. I know what addiction is and I was definitely getting addicted to cigars when I first tried them for fun, but never once have I had a problem quitting when I wanted to.
That being said, some forms of alcohol can be both healthy and beneficial when you drink moderately, but no kind of smoking can ever be good for you. Quit that shit or throw days and months (or even years) of your life away for no reason at all.
