My dad says he won't quit because he claims it's his only vice and says he likes it.
Maybe another part of addiction is just not giving a stuff?
The first step to overcoming an addiction is realizing that you actually are addicted.
OT: I've never smoked, never will. Well, except for shisha, which I kinda liked. But that isn't the same as ordinary cigarettes. Shishas contain less of the bad stuff, but I know they're not good for your health.
I respect people who smoke, but at the same time I secretly think they're weak-minded.
