I know I am a freak, but I have theory.
Anyone ever watch Men-n-Black ? The notion that aliens are among us and integrated into everyday society ?
Well. And, no I am not saying the FDA are aliens, but I believe they are part of similar cover.
What if!! Atomizers have dangers at the microscopic level that the FDA knows about and we don't ?
Could it be, that their is a little tiny alien deep inside it with little tiny alien cigarettes. Just imagine this micro alien utilizes the battery as a power source to heat juice to feed itself. A form of life support. This would enable it to smoke on your behalf at the microscopic level.
The trace amounts of the 4000+ carcinogenic chemicals are so low they can't be detected, but since the alien doesn't produce carbon dioxide, your unsuspectingly inhaling it.
It makes perfect sense! carts go bad.. cartos need replaced as all as attys.. That just means the poor alien died and one is just around the corner to replace it.
