Did they classify them as drug delivery devices out right? Was that label ever tagged onto the units? That was some of the information I could not find. You have the Premier, the Eclipse, the Next, the Accord and the newest one I can't find it's name again is pictured above and is in testing. Here is a good article.
Altria Needs Smokeless Cigarettes More Than Ever (MO)
from the above article.......In turn, the industry has identified smokeless tobacco and cigarettes as its savior. These cigarettes reduce, if not eliminate, the issue of second-hand smoke by emitting water vapors instead of actual smoke.
Seems the big tobacco industry will either help us legalize PV's or give up that road and help prove cases against them to push tobacco sales. Once they are made legal I would suspect that is when they will go around and push the little guys out of business with intellectual property lawsuits for copyright infringement.
