We already know exactly what's causing this, and it has nothing to do with THC or vape juice (vegetable glycerin). These people are vaping grey market THC carts. Grey market being the operative word, because the process used to make wax relies on using butane and other heavy solvents to dissolve the plant while keeping the THC intact. These small, backyard producers are dumb as shit and don't know how to properly remove the solvents.
