Well, the CDC has finally come out in their weekly morbidity report and state that the most likely cause of the illnesses that have swept the US, and have started a campaign of mis-information and knee-jerk calls to overly prohibitive regulations, is the Vitamin E Acetate found in black market THC "cartridges". It is often used as a cutting agent to dilute the expensive THC oil.
To be clear, reputable, licensed, legal shops like vapers.ca and many other specialty vape shops in Toronto and across Canada, do not sell to minors, and certainly don't sell anything containing any form of oil. All of our e-liquid is water based using only the highest quality ingredients.
No amount of wattage or heat can convert glycerin to oil. That's alchemy.
