@video_game_king: people smoke because the are addicted to nicotine. the fastest most addictive drug on the planet. each cigarette they smoke creates the need for the next cigarette and the next and the next and so on and so on.
they might try and kid themselves that it relaxes them. or relieves boredom, or that they like the taste or the ritual. truth is none of these are true and they are just drug addicts.
