I didn't come up with the definition, I am just telling you. You can rave about how dumb it is all day long and I agree; but it doesn't change it.
I *think* the term for E-Cigs changed to "total aersolic matter" a year or so ago, but I am sure they used the misleading term "tar" for the hnb products.
If your group/company whatever you work for testing things, arbitrarily changed a definition, that doesn't make your definition right. If I arbitrarily defined a "dog" as a small animal that purred and meowed wouldn't mean I am right. Considering HNB products are made with actual tobacco it is highly possible that ACTUAL tar is present. I do not think they changed the definition of tar. It sounds more like your company did though. Any "aersolic matter" is never going be the accepted definition of "tar" to anyone outside of your company. Anyway, I'm done.
