No shit sherlock. Everyone has a different tolerance, sensitivity and trigger points for all kind of problems to appear out of nowhere. But this advice is bullshit.

Having hard facts and learning how it affects the body goes further than "enjoy life, my granny smoked till she was 100 years old, I should be fine with 1 cigarette a day" kind of thinking.

If you ever have any accident by accident, your chances of survival or recovery is diminished for your use of harmful substances. Everything is perfect until it isn't.You're supposed to use science as a basis of making things more manageable when dealing with uncertainty. But, you'll then blame the doctors, saying how you had no any other problems with you and how healthy you were.

You're the kind of people in hospitals who say "I've never had a pill in my life and all these doctors are crazy psychopaths that say crazy things to make money off of me"

Reddit seems to be leaking.
