This is NOT going to replace e-cigarettes. It may replace the Nicotrol Inhaler, though.
E-cigarettes are NOT an alternative for nicotine addiction treatments like gums and patches, they are an alternative for cigarettes like snus or Orbs. Do not forget that!!
Intended use matters, like Elaine said. If this product is seeking FDA approval as an NRT, then it is NOT intended to be a smokeless tobacco product like e-cigarettes. Its ultimate goal will have to be to wean the user off of nicotine, not be a long-term source of nicotine.
This thing to e-cigarettes is like comparing insulin to sugar-free ice cream for diabetics. One treats a disease, the other is a reduced harm alternative for people with the disease. Very different intended uses!
That is true and intelligent people can see that but remember we're dealing with the FDA here and big pharma, so even a perceived threat like ecig’s has to be crushed.
