Well, because it is not supposed to! We developed Teabacco without any nicotine, so consumers could enjoy a smooth alternative without holding their heads after a few puffs. The only buzz you should be getting is when your friend buzzes you to pass the hookah. You will, however, notice the blend of calming and awakening feeling due to the natural caffeine that is present in our Teabacco, due to using all-natural black tea leaves as part of our ingredients.
