Vaping nicotine with e-cigarettes has taken the U.S. by storm, but now there is a new craze using the same principle: caffeine vaping.
Similar to e-cigarettes in structure, caffeine vaporizers are tubal gadgets that people use to inhale caffeine. The ingredients include: Guarana (high in caffeine), taurine (product in energy drinks), and ginseng (popular tea), notes the New York Times.
Caffeine vaporizers include a heating component that turn the ingredients into a vapor that can be cheerfully inhaled.
Eagle Energy Vapor, one brand of the caffeine vaporizers, reportedly claims that 10 to 20 puffs of their disposable inhaler is equal to a 12-ounce cup of coffee (standard serving).
It's worth noting that inhaling caffeine will likely take it into the bloodstream faster. As with traditional caffeine products, there may be side effects for people who use any brand of caffeine vaporizer, including an increase in blood pressure and/or possible heart issues.
"This isn't a medication, it's safety has not been reviewed by the FDA, and they should [exercise] caution," Dr. Nieca Goldberg, a cardiologist, told Business Insider.
Elliot Mashford, the president of Eagle Energy Vapor, countered: "We don't require FDA approval because we’re a dietary supplement."
While it's true that dietary supplements don't need FDA approval, that doesn't mean dietary supplements are necessarily safe for everyone.
That said, Eagle Energy Vapor is reportedly conducting its own clinical trials.
