It's best not to fool yourself. When you smoke a hookah, your body absorbs some nicotine. The amount is still in question, but its definitely greater than zero. Nicotine creates a physical dependence. Meaning that it makes you feel shitty if you don't consume more. Additionally, nicotine messes with the reward and punishment centers of your brain, creating a primal "electrified mouse feeder" effect. Important to note that not EVERYONE gets physically addicted to nicotine. Also important to note is the Psychological Addiction aspect. This sort of addiction can happen with nearly anything that is fun or pleasureable, such as junk food, TV, etc.. I feel it'd be extremely irresponsible to not point out the addictive qualities of nicotine. At least you can see the evidence and choose your own path.
