You do not need combustion to create toxins, if that were true we would have no need for temperature controlled devices. Heating juice, wire or wicking beyond tolerable levels will alter the chemistry. We are on the same side here, but there is a lot we need to learn before we can just let this industry continue to be the free-for-all it has been.
To this point it has been about which company can one up the other, and less about what really makes this industry...us. If some of these bigger companies would have put half of their R&D budget into some scientific research, we may not be assuming half as much as we are at this point.
boo hiss, this we is perfectly happy with the free for all, land of the free home of the brave.
