I'm at the point now where I'm really starting to think about my future health and feel guilty and start thinking about cancer and lung disease everytime I spark one up. I've smoked since my teens so around 20 odd years. Sometimes heavily when I'm drinking at the weekends but mainly light. A couple / few per day or days without one at all. But still bad of course. I guess I'm just looking for reassurance really or if that can't be given then cold hard truth it is! Have I left it too late at my age?!
