I smoke nearly a packet (50gm) per day of White Ox tobacco and I really enjoy it.
But I will not smoke close to my lenses (much) or telescopes.
I am so used to being an almost leper I put my smoke out when I go to the 'smoke shop'.
You are far more likely to to be affected by diesel particulate exhaust to promote any cancer than tobacco. This does not exonerate(tobacco) it, just puts it in perspective. There is also obviously a synergy with all these 'bad'
environmental carcinogens and mutagens. It always has been difficult to 'prove' a single cause of cancer.
It is more likely it is a series of mutagenic events and then the inability of the immune system to recognise the cancer as 'foreign'.
Why these utter b's can get away with promoting their products is for these reasons.
