Great info however it seems there are some other concerns to members here too:
Do flavored tobaccos, such as those used in Nargila, require Hashgacha?
* ANSWER:
Nargila tobacco, which is nicotine free, is available in numerous “flavors”. This product does not require Hashgacha when smoked, as smoking is not Halachically (by Jewish law) considered consumption, and therefore is not a kosher concern. However, the practice of smoking in general raises serious halakhic issues, and we strongly recommend consulting with your local learned Orthodox Rabbi about the issue of smoking.
