The Rest of the Story

Some further speculation on why I did not feel that jolt of energy throughout the day is due to the fact infusing caffeine with E-Juice can’t be done without destroying the taste of E-Juice. A cup of coffee is roughly 100mg of caffeine. To get the same effects as a single cup of coffee, the E-Juice mixologist would have to mix a very high concentration of caffeine in each bottle of E-Juice. No one is going to use an entire of bottle of E-Juice in one sitting, so 100mg of caffeine would have to be ingested in just a few short puffs for the user to feel the effects without chain vaping.

The main study finding was as follows: "The assessment of lung function demonstrated that neither a brief session of active e-cigarette smoking nor a 1 hour passive e-cigarette smoking session significantly interfered with normal lung function. On the other hand, acute active and passive tobacco cigarette smoking undermined lung function, as repeatedly shown in previous studies."
