Statistically (up until the Fake Vax anyway) about 90% of lung cancer victims are smokers. A fair number of the other 10% have had exposure to something. A small number number of non smokers just lost the genetic lottery for cancer resistance.
If she was never a smoker it is a reasonable question to ask if she had the Jab, or multiple Jabs because of the increases of various cancer rates in traditionally low risk groups since the Jab was foisted on us.
No smoking, no Jab? Just bad genetic luck.
As a doctor said to me (prior to the mRNA Jab - which may well be a new wild card on this subject), Not all smokers will get lung cancer, but most people who do get lung cancer are smokers.
Among the smorgasbord of drugs in her late son’s toxicology report was THC, of which the most common delivery system is smoking cannabis. Now, of course, the son’s habits are not necessarily shared by the mom. However, it’s crazy to me how prevalent drug use including cannabis smoking is among *all* socioeconomic classes in the S.F. Bay Area. Now of course many such people would consider themselves “nonsmokers” because they don’t use tobacco. However as has been pointed out elsewhere in this thread, there’s remarkably little research on the cannabis-lung cancer nexus. In earlier generations, there was likely a confounding on the subject due to most cannabis smokers probably also smoking tobacco. Now though there’s a newer generation of weed smokers who never touch tobacco.
