ziyath...it is already proven that smoking is harmful to health. even government warns the public. i don't think that the public is so naive to not know this. now it is the people's discretion whether they want to continue burning their lungs or not.

as for the sheesha...pass by Souq Waqif and you will see a lot of muslims smoking and puffing their lungs out and having fun. haram then? i don't really think so...
