Good point mod.
The question is what to be Machmir in, Purim or Ushmartem Meod Lnafshosaychem. (The smoking issue is not Purim itself, but that someone may get hooked, or the legal aspects)
I don’t think the Yeshivish Rabbanim “ban” anything on Purim, as they know its a Gezarah shein Hatzibbur Yachol Laamod Bo.
