Both my Grandparents who I lived with smoked 40+ a day and I was always around it, that was for about 10+ years, then they both died, one from bone and one from lung cancer
Then when I had friends who smoked around me, also going to pubs I was surrounded by smoke, and then again in clubs.. It's a horrible thing. I stay in Scotland and the sooner they bring the law for no smoking in pubs/clubs the better.
Fortunatly I now live with my mum and step-dad who do not smoke
and neither does my father.
