10ClarionSt I assume you have never heard of Roy Castle? A lifelong non smoker he died of lung cancer caused by inhaling the smoke at clubs and concerts where he performed.This is from his obituary
Illness and death
Castle was diagnosed with lung cancer in March 1992, and was told that his chances of recovery were slim and that it was unlikely that he would live for more than six months. He underwent chemotherapy and radiotherapy and went into remission later that year. A non-smoker, he blamed his illness on passive smoking during his years of playing the trumpet in smoky jazz clubs.[10] On 26 November 1993, Castle announced that his illness had returned, and once again underwent treatment in the hope of overcoming it. Several months later, he carried out the high-profile Tour of Hope to raise funds for the erection of the building that would become the Roy Castle Lung Cancer Foundation, which is the only British charity dedicated solely to defeating lung cancer. By this stage, however, his condition was deteriorating and recovery was looking highly unlikely.
During and shortly after Castle's illness, many smoke-free restaurants and cafes were awarded the Roy Castle Clean Air Award to denote their adherence to a (then voluntary) smoke-free regime.
