Re: I need some information
If you are so concerned about your fathers health i would not recommend getting him into hookah smoking. It might help him a bit IF he likes smoking hookah but certailny WILL NOT improve health status.
There is no scientific evidence that hookah does not harm you in any way and anyone getting into this hobby should be aware of that.
As much as i hate to admit it :
SMOKING HOOKAH IS NOT A SAFE/SAFER/BETTER WAY OF SMOKING
Other than that its also expensive (for some of us more expensive than cigarettes)
If you are really interested in helping him quit smoking, try getting him into a hobby. Something he likes that is not frustrating for him and he can enjoy doing with friends, preferably non-smokers.
I hope i've been helpful
