One thing I an wondering about. Is since the TA is extracted from tobacco leaves which are chemically treated during growth. Would those chemicals be extracted out and be in the TA liquid?
We all quit smokeing to rid out lungs from the smoke tar and 100's of bad chemicals. I don't want to start back up with any of those bad chemicals. Thats one reason I DIY, I know what goes into my juice,PG,VG,Flavor, and Nic.
Edited: After posting this I str8vision's thread Tobacco extraction using heated Ethanol, it had a link inwhich NET was studied. Most of that link is "over my head"> Nicotine Levels and Presence of Selected Tobacco-Derived Toxins in Tobacco Flavoured Electronic Cigarette Refill Liquids.
If anyone has read the report and understands it, can you explain it in lamens terms. Does extracting tobacco leaves extract tobacco's cancer causing bad chemicals and toxins?
The lead researcher, Dr Farsalinos, summarized the lab analysis of NETs as follows;
"The study verified that tobacco-derived toxins are lower by orders of magnitude in e-liquids compared to tobacco products. Characteristically, nitrosamines were 146-1447 times lower in e-liquids compared to tobacco products (in 1 mL liquid compared to 1 gram of tobacco), while nitrate was 1360 times lower. NET liquids contained somewhat higher levels of tobacco-derived toxins compared to conventional e-liquids, but the levels were still significantly lower compared to tobacco. Deviation from labeled nicotine content was on average 5.9% for conventional e-liquids and 1.5% for NETs, with maximum deviation being 22.1%. Interestingly, no difference between conventional liquids and NETs were observed, indicating that the flavor extraction process does not lead to extraction of nicotine from the tobacco leaves."
My take; The NET we make is hundreds of times less toxic that the tobacco it was derived from. To put it a different way, you can vape NET for an entire year and still not be exposed to the level of toxins a smoker is in a single day. Not to mention since you aren't -burning- the tobacco the potent carcinogens associated with "smoking" (Polycyclic aromatic hydrocarbons (PAHs)) aren't generated in the first place. PAHs aren't found in tobacco but are actually generated when tobacco (or any organic matter) is -burned- so are present only in the "smoke". Even so, vaping isn't 100% safe, it's just "by orders of magnitude" less harmful than smoking.
