I know.... I only buy American made juices.... have you ever visited one of these factories in America that extract the nicotine from tobacco? Do they really even exist? Or is every supplier really buying the nicotine from China (as I've heard they own the patent on nicotine extraction) and mixing it in America, thus calling it American made juice....[/quote[
American tobacco companies have been extracting nicotine for decades. They remove nicotine from one type of tobacco that's really loaded and use it to boost other varieties to make ultra light/light/full flavor cigarettes. It's also sold to pharmaceutical companies for use in NRT products.
And, China can't hold the patent for nicotine extraction because a Chinese patent means nothing in the U.S.
I'm with you on buying American made juices. I just wonder how much of the ingredients comes from China.
On another subject, no one really knows how safe continuous vaping is with PG or VG. The inhalers are made to be used as needed for asthma and fog machines aren't run 24 hours (or 16 waking hours) a day like we use PVs.
I know that my lungs are operating more efficiently since I've been vaping. Before I started vaping I tested 99% using an oximeter right after smoking an analog. After vaping, my lungs really became clear.
Once or twice a month, if I vape all VG liquids as day, at night I can tell a difference in my perception of oxygen levels. I switch to PG the next day, sometimes mix a little VG in for more vapor and I'm good.
I have a friend who owned a fish restaurant for 20 years or so. He was usually the chief cook and fried most of his fish in vegetable or peanut oil. He had to sell the restaurant and open a pizza place because his lungs were damaged from inhaling all the grease fumes from the fryers. VG is vegetable glycerine. I do hope that someone will say that there is no comparison and provide links to prove that.
We can't assume complete safety as illustrated by the clip from this link. BTW, glycerol is the common name used for vegetable glycerin.
Glycerol - Wikipedia, the free encyclopedia
On May 4, 2007, the US Food and Drug Administration advised all US makers of medicines to test all batches of glycerine for the toxic diethylene glycol.[17] This follows an occurrence of 100 fatal poisonings in Panama resulting from a Chinese factory deliberately falsifying records in order to export the cheaper diethylene glycol as the more expensive glycerol.[18] Glycerine and diethylene glycol are similar in appearance, smell, and taste. The US Federal Food, Drug, and Cosmetic Act was passed following the 1937 "Elixir Sulfanilamide" incident of poisoning caused by diethylene glycol contamination of medicine.
PG sources
Propylene glycol - Wikipedia, the free encyclopedia
Industrially propylene glycol is produced from propylene oxide .[3] Different manufacturers use either non-catalytic high-temperature process at 200 °C (392 °F) to 220 °C (428 °F), or a catalytic method, which proceeds at 150 °C (302 °F) to 180 °C (356 °F) in the presence of ion exchange resin or a small amount of sulfuric acid or alkali.
Final products contain 20% 1,2-propanediol, 1.5% of dipropylene glycol and small amounts of other polypropylene glycols.[4]
Propylene glycol can also be converted from glycerol, a biodiesel byproduct.
The glycerol/biodiesel source is a little scary. Glycerol is vegetable glycerin (VG).
So, we can't completely know that vaping is safe. We just know that we feel better on juice than analogs.
