My friend just recently acquired what appears to be a .... ton of new juice from "High Voltage Vapors". This juice has the claim about being caffeine infused. My first question is that is it just a scam, or do they legitimately infuse caffeine? And if they do, is it potentially dangerous? The idea of inhaling caffeine seems to raise a red flag for me. However, if the amount of caffeine is minuscule, maybe it's not any more unhealthy than other juices. Thoughts?
