Tobacco Absolute (TA) is a commercial product made by various manufacturers (most famously in Bulgaria) that was used originally in the perfume industry.

Tobacco Extract (TE) is the same essential oil of TA suspended in a base of PG rather than alcohol. Usually sold in diluted form, TE is still very concentrated.
Used very sparingly and with restraint, TA/TE adds a smoky component to eliquids that is reminiscent of burning tobacco. Using a little more imparts to eliquids a dirty ash tray flavor that some vapers (who are usually ex-smokers) actually like. Using too much, however, ruins the flavor of the juice.
