Yes Roy Castle died of lung cancer but it was never proven that secondary smoking was the cause...it was just assumed!!
Have a quick read of this article:
http://www.independent.co.uk/life-st...ul-476472.html
And here is a small part of it:
Reputable research shows that a non-smoker inhales between a 500th and 1,000th of the toxins inhaled by the smoker himself. No matter what poor Roy Castle believed about the effects of years in smoky jazz clubs, there is little scientific proof that secondary smoke causes cancer.
Also read this from the British Medical Journal

The results do not support a causal relation between environmental tobacco smoke and tobacco related mortality, although they do not rule out a small effect. The association between exposure to environmental tobacco smoke and coronary heart disease and lung cancer may be considerably weaker than generally believed.
What makes this study more significant than any other is that it took place over a 39 year period, and studied the results of non-smokers who lived with smokers..... meaning these non-smokers were exposed to secondhand smoke up to 24 hours per day; 365 days per year for 39 years. And there was still no relation between environmental tobacco smoke and tobacco related mortality.
This report was of course silenced in the media; however in light of the damage to business, jobs, and the economy from smoking bans the BMJ report should be revisited by lawmakers as a reference tool and justification to repeal the now unnecessary and very damaging smoking ban laws.
Also significant is the World Health Organization (WHO) study which concluded "..secondhand smoking doesn't cause cancer..."

Passive smoking doesn't cause cancer - official
By Victoria Macdonald, Health Correspondent
The results are consistent with their being no additional risk for a person living or working with a smoker and could be consistent with passive smoke having a protective effect against lung cancer. The summary, seen by The Telegraph, also states: "There was no association between lung cancer risk and ETS exposure during childhood."
And if lawmakers need additional real world data to further highlight the need to eliminate these onerous and arbitrary laws, air quality testing by Johns Hopkins University, the American Cancer Society, a Minnesota Environmental Health Department, and various researchers whose testing and report was also peer reviewed and published in the esteemed British Medical Journal......prove that secondhand smoke is 2.6 - 25,000 times SAFER than occupational (OSHA) workplace regulations
