I just finished reading ALL of this thread, Whew!
One thing I found missing in this thread of concerns for ingredients/symptoms is that E-Cig Newbies seem to smoke carts dry and we know that the Polyester fibers inside these will burn/melt (or perhaps leach chemicals when heated?). Yikes!
Could this be some of the problem with lung/sinus issues when we first start e-smoking?
So, my concern is: What are those cartridges made of? Nylon or Polyester is my guess (I collect antique/vintage/interesting new sewing buttons, and I know that a majority of the modern Synthetic Polymers which are molded into buttons are being imported from China). What is happening if the plastic cart or the poly batting is overheated by the atomizer? Chemical leaching? Have the plastics in the carts and poly batting been tested by anyone?
When topping off my carts I've noticed that threads of the polyester batting start to stick out further and further from the top even if I'm tapping them down with tweezers. Is this a concern and something we need to maintain as well by trimming or replacing batting more often? Are they melting/burning/leaching chemicals while I'm vaping? Is this something we are breathing?
I think it's my biggest concern about
long term e-smoking since it incorporates these plastic products from China. I would rather the carts were metal (especially since they are reused/heated over and over) and wish they had a fine metal mesh screen to snap over the top to hold in the poly batting or that there was a better way to get the liquid to the atomizer (other than dripping - which I never do).
I hope Satire or someone with chemical experience will address the cart plastic/polyester chemical issue (if it's been talked about, will someone post the link to the forum area for me? The info. on the entire e-cig forum is FAB but overwhelming, as I've spent hours just reading this thread!).
Thanks!
