Not Sufficient Caffeine to Be Effective Stimulants
As said before, it is possible to vaporize caffeine. This way can deliver the stimulant into the body and lungs more quickly than drinking a cup of coffee. However, the amount of caffeine in these products is not enough to stimulate the body. Depending on the brands and devices, the exact numbers can vary. But in most cases, caffeine in these vapes are far less than that in a typical cup of coffee. Many scientists believe that adding the caffeine is just a marketing trick to make people become interested in their products. Manufacturers can actually put many other ingredients into the vape and make people get addicted.[5]
