What it's like to vape caffeine


Vancouver's Eagle Energy Vapor sells a caffeine vaporizer. Similar to an e-cigarette, the slim electronic pen-shaped device delivers a dose of caffeine, taurine, and ginseng. Each vaporizer is good for 500 puffs, and 10-20 puffs are needed to feel the effect. A 10-pack sells for $75.

Some of the staffers at Huffington Post tried it. Reactions ranged from "Oh my God, my heart is racing so fast. Am I going to die?" to "I love this thing! I feel so good."
