I think there comes a Point where the Effort should be Placed more on Trying to Fight for Fair and Equitable e-Liquid use than to Argue if a Nicotine Containing e-Liquid is a "Tobacco Product".
Because Very Shortly, e-Liquids which contain Nicotine derived from Tobacco Plants will have a Statutory Definition as a Tobacco Product. And that is Not Going to Change.
Have you Written your State and Federal Representatives telling them what type of e-Cigarette Market you want?
Have you ask your Husband/Wife to do the Same?
Have you ask your Friends and Family to do the Same?
Have you gone to this Site and Considered what they Suggest? CASAA: First Call to Prepare for FDA Proposed Regulations - Prepare Draft Comment
Discussing if Nicotine containing e-Liquids should be a Tobacco Product or Not is Fine. But they are Going to be Legal Defined as such soon.
So maybe More effort should be Placed in Trying to shape how we can Still Use these "Tobacco Products".
