36mg isn't a dangerously high dosage. I know some people that vape that level. Now 100mg nic makes me nervous. But do I use it? Yes .. While properly attired, I dilute it down to a more managable level for my DIY stuff. Would I ever vape that level? No! That would not only make me sick but could be dangerous.
Last question: have I ever gotten any juice in my mouth. Many times. But I vape at a reasonably safe level. I would never willingly -drink- it. That's just plain stupidity. But the mg levels, that most of us are exposed to on a regular basis, are much safer than the pure nicotine you referenced. It's all relative. And therefore I think it's a pretty silly question. (and why you may be getting the responses that you did!)
