IS SMOKING BAD FOR YOUR HEALTH?

DAF HASHAVUA      SHABBOS 86B          IS SMOKING BAD FOR YOUR HEALTH?        עכו"ם דלא דאיגי במצות- דאכלן שקצים ורמשים The Gemoro asks if the human physiology between an עכו"ם and a Yid are the same or they might be different. The Gemoro remains with the question and has no answer.  The Chasam Sofer* writes that since the Gemoro has no conclusion, therefore we must assume that the science of medicine is inconclusive for Yidden since it is all based on bodies of Goyim which might be different than bodies of Yidden. We may eat on Yom Kippur based on a doctors advice not because his advice is true but because of ספק פיקוח נפש and that's enough to be מתיר איסורים. According to this Chasam Sofer, SMOKING IS  BAD FOR YOUR HEALTH  is incorrect SMOKING MIGHT BE BAD FOR YOUR HEALTH is correct (only ספק) ע"ז ל"א*
