All this talk of vaping illnesses has me thinking about all the counterfeit cartriges that are in circulation right now and have been for the past while. I had one that i stopped using immediately after i felt pain in my throat unlike any normal smoking pain. Never happened again since i don't use carts anymore. I just want to warn people that unless you know with absolute certainty that the carts came from a reputable source, do not buy, sell, or use them. The last thing we need is people getting sick from homebrew bullshit from people who don't know what they are doing and are just trying to make a buck. It hurts our society and also our chances to finally fully legalize this stuff. So if you are out there making carts in your kitchen, be careful with what you are doing and have ample research to know what solvents to use, what is safe to inhale, are there any contaminents that you aren't aware of? Metal pot or borosilicate glass? Just know that you are playing with peoples health when you make things that people will inhale. Leave it to the pro's.
