I reason that smoking cigs/tobacco is only one possible FACTOR involved with health,
I reason there is advantages and disadvantages to smoking cigs,
but that is the way it is for many things in life.
Personally, I find the advantages outweigh the disadvantages for myself,
so it might be a personal thing.
Sorry, but the hypocricy meter starts going off, as soon as anti smokers start preaching their anti smoking things.
(ie: iatrogenic deaths are a leading cause of death, worse than cig smoking)
(doctors or medical workers so-called 'errors' is what 'iatrogenic' means, I don't know why they invent such a strange word for when the doctors kill people)
oh, and 'cause of death' is often a difficult thing to prove, or to pin on any one specific factor.
Rather, cause of death is often 'syndromes' or collections of factors, it isn't usually known how much any one factor affected/effected that though
