Herbert A. Gilbert, “Smokeless Non-Tobacco Cigarette” #3,200,819 (United States Patent), 17 August 1965 was a patent for the invention of (what is referred to now as) “the electronic cigarette”.
ENDS stands for “Electronic Nicotine Delivery Systems” and this patent is among the first developed. The “traditional cigarette” has a barrel that is 90% tobacco and 10% “additives”.
The combustion of a “traditional cigarette” produces “cigarette tar”. ENDS solves the “cigarette tar” production problem, by simply delivering “nicotine” without burning,
Cigarette “recipes for the 10% additives” create unique “brands” with the choice of additives. “Menthol” is a very common additive; since, menthol produces a “numbing” sensation in the throat of the smoker. “Flavor compounds” such as liqourice, chocolate, sugar, … , etcetera, make up the rest of the 10% additives.

TEN stands for “Tobacco Extract Nicotine”: and nicotine is a plant alkaloid with the following chemical properties.
Empirical Formula: C10H14N2
Nicotine taste classification: Bitter.
Molecular Weight: 162 g/mol
Molecular 2D-Structure: (shown in diagram below).
SMILES (canonical): CN1CCCC1C2=CN=CC=C2
SMILES (isomeric): CN1CCC[C@H]1C2=CN=CC=C2
“Tobacco Extract Nicotine”, TEN is an exogeneous-metabolite “inhaled” without burning tobacco (free of toxic substances). “TEN” is obtained by extracting 99.9% nicotine from dried tobacco leaf powder. Today, in the year 2021 “TEN” a viable tobacco product from the 1965 patent role of ENDS “Electronic Nicotine Delivery Systems”.
