To oomis,
We were talking if it’s similar enough to get the heter of “Hakol Doshin Bo”; it doesn’t have to be exactly the same. Also, as far as I know this heter only applies to smoking yourself -whether you are oiver “Guard your health exceedingly”, it doesn’t apply to smoking around someone else. If you smoke around someone else & they don’t want to breathe in second-hand smoke, there should be no heter. (Children we would assume don’t want to breathe in smoke -you don’t ask them.)
