NONE and why should you?
the only one who are entitled to try and sue are really old people like in their 60's and 70's because they started in the 1950's and 60's when their was still tv commercials and no one really knew how bad it was...(oh yes they did)
But your daughter started when she was 16-17 that would have been 1974-1975, and kid back then knew better then to start smoking.
So it is a personal choice and she knew the riks so she should take full responsibility for her actions, even if it killed her.
