Although this is only one study, it is interesting:
“Shisha is an Arabic water-pipe in which fruit-scented tobacco is burnt using coal, passed through an ornate water vessel and inhaled through a hose.
The Centre for Tobacco Control Research said it was difficult to know exactly how much carbon monoxide one cigarette produced, due to the differences in smokers’ inhalations.
But measuring carbon monoxide in exhaled breath showed a normal non-smoker’s level to be three parts CO per million parts of air (ppm) (3% of blood not working properly), a light smoker to have 10-20% of blood not working properly, and a heavy smoker 30-40%.”
I suppose it will give the anti-smoking people something to do. Designing new posters, calling for film scenes with shisha to be rated 18+, and walking around the streets badgering people about their habits.
