My parents both used to smoke, my mum and step dad still do and it was always a huge inconvenience having to wait for them.
A lot of my family and family friends always smoked and drank, I spent a lot of time around them when I was younger and decided I never wanted to be empty shells if disappointment and unhappiness that I see a lot of them are.
I've never tried smoking and I don't really want to, you only get one life don't spend it getting hooked on something that doesn't last.
