The answer is already simple: WTA is the result of isolating nicotine and the associated minor alkaloids from tobacco.I think it may just be trying to simplify an answer. I did/do get some WTA satisfaction from the NETS I tried, though the only ones I liked and stayed with were Todds from Vaperight and 2 from PrimeVape . ... and to be fair, only tried theirs and GoodEjuice (did not like theirs), maybe a couple others that i cant now remember... Gonna try making my own at some point.
If they say "Naturally extracted tobacco or NET e-juice gives the same whole tobacco effect as WTA" that's the first time I've ever seen anyone make that claim.
