GAW -“If the Chazon Ish knew how to do brain surgery from learning Toirah, Kal V’Choimer the P’nei Yehoshua knew what smoking would do to the lungs from his vast knowledge of Toirah! And still, the P’nei Yehoshua said smoking is healthy. Either “Nishtanu HaTeva” (which I have never seen in an anti-smoking P’sak) , or the studies were not done on Yidden, who react physically differently than Eino Yehudim (as per Chazal).”
Your post is way off!
First of all, you didn’t address “zvei dinim”‘s points:
“1. The Pnei Yehosuah (Shabbos ??:) says
???? ?????? ?????”? ??? ??? ?????? ????
The P’nei Yehoshua only says ????.”
Do you know the difference between Nirah and it definitely is?
“2) The Pnei Yehoshua is talking about the sugyah of ???? ??? on ??? ???, where the criteria relevant has to do with the REASON the person is doing it and not the actual RESULT.
This is why the Pnei Yehoshua says ???? ?????? ?????”? ??? ??? ?????? ???? which has nothing to do with the actual effect.”
So this point is that maybe he is talking in the here and now and therefore it’s Oichel Nefesh and can be done on Yom Tov, but he knew that in the long term it was dangerous to do.
Second of all, your deduction that it must be either people changed or Jews aren’t affected by smoking is No proof. Because even without the things Zvei Dinim mentioned, even if you want to believe the Pnei Yehoshua said it’s healthy – you simply can say tobacco in itself is healthy, but nowadays the way they make cigarettes and similar stuff is with many additives. It very well could be this is what makes smoking dangerous!
