How old do you have to be to get into a hookah lounge?

Kind of, that is because it is flavored tobacco. In the laws eyes buying any form of tobacco under the age of 18 is illegal, however you can smoke hookah at 16 but you can not own it. There is an alternative that is legal to buy at any age. It is called Soax which is herbal that contains no tobacco and none of the harmful chemicals like nicotine. It is not illegal for minors to use this due to it being a non-tobacco product.
