this is probably a dumb question, but can caffeine be vaporized and absorbed like nicotine? i know that chemically they are similar, i wounder if it would work? if its already out there somewhere let me know, i would definitely want to try it! someone that is more familiar with creating e juice and the chemical properties of Nicoline and caffeine if its even possible.. i would love to know. imagine your morning vape actually waking you up like a cup of coffee or a monster.. i think it would be awesome!
