Similar Nicotine-Friendly Delivery Systems at The Lung Injury’s Center
Many caffeine vapes come with the same kind of drug delivery mechanism as in e-cigarettes. That is a combination of caffeine and various oils, including vegetable glycerin and propylene glycol. These e-liquids deliver the desired drugs to the smoker by heating and turning the solution into a white haze. While there is still no conclusion about the safety of these products, they have quite the same mechanism as many products, which are associated with many lung injuries over the past few years. Researchers have not found out which exact substances are the main culprits. However, they believe that vaping might irritate your lungs and lead to breathing problems.[6]
