What is shisha, and what is actually in it?
Shisha (also called hookah, narghile or hubbly bubbly) is a way of smoking flavoured tobacco through a water pipe. The tobacco is a sticky, molasses-based mixture — usually tobacco leaf, glycerine, molasses or honey, and flavouring — sold as brands such as Al Fakher, Starbuzz and Savacco. A portion is packed into a clay or silicone bowl, covered with foil or a heat-management device, and heated from above by charcoal rather than burned directly.
When you draw on the hose, hot air passes over the molasses and vaporises the glycerine and flavour along with the tobacco. That smoke travels down the stem, through the water in the base — which cools it and takes the harsh edge off — and up the hose to you. That cooling is why shisha feels smoother than a cigarette, and why a typical session lasts far longer.
