(4) I found a thread on a vaper forum about the toxicity of e-liquid: http://www.e-cigarette-forum.com/forum/new-members-forum/160082-information-dangers-lethality-eliquid.html -- it shows that e-liquid is safe for its intended use, even if you get some in your mouth, which you should spit out. I was curious about this b/c I saw in some video an e-liquid package marked as "very toxic".
