Sherid is 100% correct. Big Tobacco has followed its own path to marketing what might be called a smokeless cigarette. The most recent attempt is the Aria from Philip Morris. It's a misting device, rather than a vaporizer.
But also look at earlier attempts for the Accord, Premier, Eclipse, Heatbar. All of them used tobacco rather than liquid, but the tobacco was soaked with propylene glycol and the product produced more vapor than smoke, since the tobacco was not burned. It was heated by a charcoal lump in the tip.
And everyone saw what happened to the Favor -- banned by the FDA.
China beat Big Tobacco to the market with a fully electronic, vaporizing unit. Rest assured that PM and RJR and Lorrillard have been at work on similar devices, likely without sufficient success to market a product. Maybe Big Tobacco recognizes that a fully electronic product delivering a nicotine-laced chemical concoction would be a "new drug" and "drug delivery device," thus requiring years of clinical testing.
The goal has been a true tobacco cigarette that didn't "smoke".
Let us know what you get, Sherid. As you said, Big Tobacco execs are not fools and are not stupid.
