No one ever said PVs were 100% safe. The whole point is that they are safer/cleaner than tobacco smoke.
What people who use the "anti-freeze" arguement often fail to notice is that the 1% DEG is the WORST thing the FDA could find in ONE of the 18 carts tested and it's in much higher amounts in tobacco cigarettes! No tar, no arsenic, no ammonia, no carbon monoxide, etc...no one (Anti-PV) stops to think about how much cleaner that is than what is found in a real cigarettes.
The WORST thing they could manage to find was the 1% DEG, so they had to play it up. If they could have found anything worse than a tiny amount of DEG, you KNOW they would have been shouting it from the rooftops! Is DEG worse than inhaling arsenic or ammonia?
By ONLY finding the DEG as the "worst" ingredient, the FDA confirmed for me what I already knew - PVs are less toxic and, therefore, less deadly than tobacco smoking. And I don't use Smoking Everywhere 555 High brand cartridges, nor any tobacco flavors, so I'm not worried about DEG exposure, either!
I totally agree with you on this point. But at some point, we need to shift the argument from PV to Analogues, to PV to our bodies.
