Ok so for anyone that is thinking that cotton MIGHT have some relatively toxic / hazardous chemicals in it, you would be correct.. pretty much any cotton you will find now days is a GMO product, because it just not cost effective to grow anything but GMO cotton...
Cotton is mostly a complex structural polysaccharide, better known as cellulose. that is not really toxic at all, unless you burn it, then the fumes are quite hazardous.
but none of that is what really concerns me. you see when cotton comes off the plant its about %95 cellulose. the other %5 is a combo of protein, ash, wax, sugar and organic acids... and the way they remove the other %5 is with a chemical cocktail of "selective solvents". and even then its only %99 percent cellulose. basically i THINK its going to be better in the long for your heath to vape cotton rather than smoke analog cigarettes. but i cant really say. cotton was never designed for vaping. its something the vaping people have re-purposed with a decent amount of success.. personally i will stick with amorphous silica. because amorphous silica is one chemical made from 2 elements, no risk of burning up and inhaling silica wick fumes in an e-cigarette and its not a GMO product.
(i am all about freedom of choice i am not saying GMO products are bad, They are just not for me.)
