I do believe most smokers today are troubled by something, yes. In the past, it was culturally acceptable but not so much anymore (especially in Northern Europe, I can't really talk for the US). Most people who are bothered by something have a sort obsessive habit, e.g shaking one leg or a finger, touching his hair, smoking, chewing something, eating salty or sugary things. Just an observation.
