HASHEM IS EVERYWHERE
allow me to explain, while i disagree with much that AGUG has posted. i would be careful say “its assur , its written straight in the torah”. as much as we would love the torah to agree with our opinion. we cannot decide for ourselves,halacha says what it has to say the torah stes the guidelines for the halacha,not us. not every bad habit,trait or practice is muttar or assur .it may be bad middos, arrogance carelessness,but you cant put your own ideas into halacha! we therefore consult our rabbanim
PS just to quote you. R MOSHE FEINSTEIN discusses the dangers of smoking, and says that its muttar
WHILE ITS A DISCUSSION AMONG TODAYS POSKIM IF THAT PS’AK STILL STANDS. CAUTION IS ALWAYS URGED WHEN PLAYING WITH FIRE!!!(PUN INTENDED)
