People who smoke shisha would inhale 26 times the recommended limit of uranium.
I had acquaintances who believe smoking shisha is way safer than smoking cigarettes. It's a common thought that the water purifies the smoke and eventually makes the smoke safer. I had a different view and we would go on too argue for hours but there was no way I would logically prove this to them.
Luckily, I found this article. Shisha smoke, according to the research, isn't filtered and the smoker could end up inhaling harmful substances like nickel and uranium. No form of smoking is safe I guess. I hope they read it and find it educative.
