I already have a few bottles mixed at 3mg/ml, letting them steep a bit.I started vaping precisely because I wanted to get nicotine into me without smoking after I read that it might help with MS-related brain issues. Obviously, I can have no way of knowing whether it did, but what the hey.
I'm at around 10mgs/ml, but you're starting from 0, so starting low sounds like a sensible way to go.
