Well, I've got Four, so that should keep me going for a while.
I have got to read up on this tank cracking business. Yikes.
Thanks.
While there is still a lot that we don't know about the effects of some of the ingredients in liquids, especially flavorings, it's likely not as bad as it sounds.
It's just a reaction that some juices have with certain types of plastic. A reasonable comparison might be to look at how chlorine bleach reacts with ammonia. Bleach is generally considered safe to use and most of us keep some in our households on a regular basis. We even swim in swimming pools with chlorine in them.
Mix that generally harmless bleach with some ammonia and you have a very toxic substance. It's kind of the same thing with some liquids and some plastics. The liquid is generally considered safe to use. It just doesn't go well with certain types of plastic.
I don't think the liquid itself is going to melt your lungs or other bodily tissues but I wouldn't recommend vaping it from a tank of which it melted the plastic. That same liquid should be fine when vaped from a glass tank.
