Okay so this is just a newbie's research. Some interesting stuff I found on wikipedia, so take it with as many grains of salt as you want....lol
Ethylene Vinyl Acetate
This is used to adhere the extra strips of paper in fire safe cigarettes that makes them "go out" if you do not actively smoke them. This stuff is not biodegradable within the body. There have been no major studies on the long term risks posed by the inhalation of fumes produced by the use of this substance in cigarettes. This substance is used in hot glue sticks carpet glue, plastiv wrap, foam rubber used in shoes, floats, fishing gear, book binding, cling wrap, paint, and diesel fuel to name a few. http://en.wikipedia.org/wiki/Ethylene-vinyl_acetate
Propylene Glycol or pg
As most of us know by now this stuff is one of the ingredients used in e liquid to make it vaporize. It is classified as GRAS or "generally recognized as safe" by FDA as a food additive. It shows no evidence of being a carcinogen. "Studies conducted in 1942 by Dr. Oswald Hope Robertson of University of Chicago's Billings Hospital showed vaporized propylene glycol inhalation in laboratory mice may prevent pneumonia, influenza, and other respiratory diseases. Additional studies in monkeys and other animals were undertaken to determine longterm effects, especially the potential for accumulation in the lungs. After a few months of treatment, no ill effects were discovered." This substance is often used in oral, injectable, and topical pharmaceuticals, as a food additive, moisturizer, in fragrance oils,
antibacterial lotions, fog machines, paintballs snus, beer, non-toxic antifreeze, coolant, pipe tobacco (ummm hello this is inhaled has the FDA said anything about this?), deodorant, tattoo ink, and more (I named a few that stood out). PG is known to cause allergic reactions in some people, but don't most things. http://en.wikipedia.org/wiki/Propylene_glycol
Vegetable Glycerin, glycerol, or vg
We all know that vg is used in e liquid along with pg or sometime instead of pg. It is classified by the FDA among the sugar alcohols as a caloric macronutrient (used in sweeteners). It is used as a thickening agent in liqueurs, as a food additive, filler in low-fat foods, in nitroglycerine,
snus, pharmaceutical and personal care products such as cought syrups,
mouthwash, soap, and personal lubricants. http://en.wikipedia.org/wiki/Glycerol
So this is just my two cents, but PG and VG look a lot better on paper than EVA. PG and VG are used in products that are commonly either injected, absorbed, or swallowed and in the case of pipe tobacco even inhaled into humans. EVA is used to glue things together. I realize that PG and VG have not had extensive research into the harmful effects they may have when inhaled into the lungs, but this ethylene vinyl acetate is in the same boat. I think we as adult human beings are smart enough to realize that there are risk factors when we take anything into our bodies, and when we do so we do it at our own risk. I think we need to tell the FDA where they can shove it.
