Smoking ciggarettes is stupid.
They kill millions of people worldwide every year, and they don't get you high.
I'm bored of hearing people say oh addiction is a disease and so on ... I'm not saying it is, and I'm not saying it's not.
BUT MILLIONS OF PEOPLE HAVE QUIT SMOKING.
If you have people you love in your life, you should be able to quit so you can be there for them as long as possible. It's not that big of a deal.
