What Are Caffeine Vapes?
Instead of sipping a cup of coffee in the morning, now we can inhale it. Caffeine vapes are designed to help you take in caffeine by smoking. They contain many active ingredients as in energy drinks, including ginseng, taurine, and guarana. Similar to e-cigarettes, the device comes with a heating component to vaporize the inside ingredients to give you a stimulating hit when smoked. This coffee alternative can energize you without the need for drinking coffee. 
Are Caffeine Vapes Safe?
The answer is still unknown. Since caffeine vapes have just been introduced to the market, it takes time to assess its safety. Also, the US FDA has not reviewed this product because it is classified as a dietary supplement rather than a medication. In general, taking in too much caffeine, no matter in vapor-form or from energy drinks would lead to many side effects, such as jitteriness, upset stomach, lightheadedness, or fluttering heartbeat. At an excessive level, it would trigger heart issues and make your blood pressure spike. Inhaling even allows caffeine to be absorbed more quickly into the bloodstream. With coffee, this stimulant is often diluted with water or milk.
