What is the effect of inhaling smoke from shisha/hookah(water pipe) and force it towards.. *read on*?

I am going to try to make sense of that question. Either you are asking how you force the smoke to your brain? or What are the effects on your brain?

You can't force the smoke to your brain.

The effects the tobacco will have on your brain is called a nicotine buzz. This is usually only obtainable with a higher content (0.5%) of certain shisha brands like Romman, Nakhla, Tangiers or Fusion.

This is caused by the content of the nicotine and it's purity, unlike other tobacco products, the nicotine goes quickly to the brain. The buzz is typically only strong within the first 10 minutes and will diminish but heavy inhaling can keep a mild buzz if desired.

ho0kah is not anything to be worried about, its just something to make you feel "good", there is no effects and you really can turn it on your brain.

look on wikipedia I think there isn't anything as bad as smoking or smoking weed.
