Another factor we shouldnt forget is that normally nicotine is mostly in a bound form already, not much is freebase. The super pure nicotine is nearly all freebase, but that's before being added to PG/VG. There might be something going on there that nobody really knows as yet. We think it's just dissolved and while any bonding is likely not strong it might be signicant in some way, perhaps some other way (not a bonding issue exactly).
Indeed, and not just "before being added to PG/VG". Before being heated to beyond its boiling point in the presence of copious free oxygen and metals. I have come to believe that no matter how pure the juice, very little freebase nicotine actually makes it into the body when it's delivered this way. Whereas I can well believe that a lot more is delivered in the confines of a cigarette, with a moving heat gradient and depleted free oxygen (the air being drawn through the highest temperature combustion zone and consumed by the combustion before it reaches the zone in which nicotine is being evaporated from.)
Does anyone actually make an ultrasonically atomized ecig ATM do you know? I've seen Ruyan's patent, but I'm unable to find any devices on the market that use this principle.
