Re: No foil ?
Foil is only used for flavored tobaccos, so pretty much anything most of us are smoking.
If you go to Egypt, the old school men would not be caught dead smoking flavored tobacco. As far as they are concerned, apple flavor etc. is for women and tourists.
They smoke a type of unflavored shesha, which has a slight honey smell to it, and this one is smoked with no foil. As far as I know this is the only one.
When they smoke it they use far less tobacco then we would with a flavored shesha. The bowl used for this is more shallow, and the tobacco normally would be changed every 15 minutes or so.
I tried it once. It is very strong, and nowhere near as nice as a good flavored shesha.
