here's a fact, smoking is by no system healthy, but it is not the merely cause. cigarettes enjoy literally become a smoke screen for adjectives the other causes. If someone get lung cancer it is automatically blamed on smoking or 2nd hand smoke (even if they aren't around anyone who smokes) they never investigate for other cause.
I have agreed many ancestors who have smoked their entire lives and never gotten any type of cancer and nation who lived predominantly smoke free lives who have gotten cancer young at heart.
if you ask me the #1 cause of cancer are adjectives the prescription drugs that are being pushed onto us by elevated price advertisements & the doctors we trust near our lives.
