Does that include hookah?

Just because it smells nicer and we pretend water filtration helps, doesn't make it heathier. Hookah is often worse because a long Hookah session can have more nicotine than a pack of cigarettes.

I imagine the study included it in the data but did not differentiate it, so you can’t make a specific deduction about it.

If anyone actually has details please correct me.

Hookah is tobacco, so I assume yes.

Pretty sure an average hookah session is the equivalent to 1-2 packs of cigarettes.

Yeah, I got into a Wikipedia edit war about this. The WHO has some studies showing that an hour of hookah smoking puts about the same amount of tar in the lungs as 20 cigarettes. I think the theory was that the cooler smoke is better tolerated and smokers leave it in their lungs longer.

I eventually gave up maintaining the page, and the hookah vendors who were my rivals have completely remove the citation. Also, it was hard to find in the first place and I don’t have access to a college library anymore.
