RJR's famous "smokeless" cigarette, Premier, heated and aerosolized
tobacco to deliver nicotine (although no one was sure just how effective it was at doing this, much like PVs). It was clumsy and awkward (people actually had to be instructed on how to light it) so they took it off the market within a year. Not wanting to lose the billions they spent on development of Premier, they introduced version 2, Eclipse, in the 90s. This used a carbon tip to heat
tobacco to give off a vapor; very little
tobacco was actually burned in the process of smoking an Eclipse and no ashes. Regardless, the American Cancer Society argues it still produces carcinogens (true because it was using plant material with the famous 599 additives to produce the vapor). I'm not sure but I think Eclipse might still be floating around somewhere. So while RJR stuck to its beloved tobacco leaf it was the first company to introduce a product that used vapor instead of smoke to deliver nicotine to cigarette users. They just weren't clever enough to do it right.
