As the mysterious vape deaths continue, more data continues to be released about the various harmful chemicals found in vape devices and vape liquids. Some believe that Vitamin E acetate is an issue. Pesticides certainly can be an issue, as well as heavy metals.
All I can say is that I have personally tested every vapable thing on myself and my wife without issues. I've not received any reports from any customers of any issues aside from one person who seemed to be sensitive to DMSO. I do not use Vitamin E acetate and nothing I know of that I sell contains pesticides. EDIT: Some carts were harsh to vape, especially D in DMSO. I recently discovered that by adding a couple drops of vinegar to the cart & mixing it well, all the harshness disappeared!
Hot vapors from anything are harsh on the throat & lungs, so make sure not to inhale hot vapors. You can hold the vape pen button for max 2 seconds each time in order to prevent hot vapors from burning your insides.
NEVER vape if your cartridge has run dry. This "dry vaping" is very dangerous for your health. If you notice the vapor tastes very different from usual, make sure you are not dry-vaping the coils and thus inhaling lots of heavy metal vapors.
Furthermore, I would suggest limiting your vaping to the least amount possible. Nobody knows what is going on here, so caution is paramount.
