Atomic Fireball has to be one of my favorite flavors so far.
It smells and tastes exactly like those Red Hot candies: very cinnamony. At first I thought that cinnamon would not work well with hookah, but Hookah Freak made it work beautifully. There is a lot of cinnamon flavor as you smoke, but your mouth never feels like it's on fire and needs a drink of water.
There is also a decent buzz and the clouds are phenomenal.
