asdfghjkl: I once heard a story about a man who sued his own son because of an injury he suffered in his son’s house. The home owners insurance covered it so the son didn’t lose anything.
moish01: I have never smoked. I can’t even stand being around someone who has recently smoked because of the smell on their breath and clothes. I have many friends who unfortunately do smoke. I also have many friends who I believe have never tried a cigarette in their life.
yros: You asked, “where is the issur?” I ask you, if there is no issur then why don’t you do it the rest of the year and if there is an issur, why is it muttar on Purim? You also asked, “what is the difference between drinking and smoking?” If you learn through the halachos of Purim you will see that there is a mitzvah to drink wine on Purim. There are different opinions and minhagim about how to fulfill this mitzvah. Some people even extend the mitzvah to drinking alcoholic beverages other than wine. Everyone agrees that if it is damaging to your body you should not drink. No where in halacha does it say anything about a mitzvah to smoke on Purim.
