I don't smoke and I can't have a friend that smokes. I personally see smoking as a vice. Why? The people that are smoking around my city always look unkempt and are generally disorganized. A smoker can't come around me unless I don't know the person smokes.
I do not smoke. I tried one or two cigarettes when I was younger out of curiosity. I did not like it! Good thing, I did not become a smoker even though I was surrounded by my classmates who are smokers.
