Damn straight I'm an expert, but that doesn't help her at work, when I'm not around, when she forgets stuff in the AM. I can do all I can do but I work 2 jobs and am not there 24/7 to see her through. I am more concerned she will not be SATISFIED with the vape and return to smoking. That is all. I have started, under my supervision, about 30 people vaping. 7 have stuck with it. They have called me, I have loaned gear, I have shown how to's at homes, on skype etc...Sometimes people dont want to play with something for 20 min to see if it works better when they can just light a smoke. Has no one else experienced this trying to convert a friend?
Actually learning to deal with the gear and its problems is part of becoming a vaper. You can help her avoid some of the pitfalls by starting her on a good kit. You can teach her the process fro troubleshooting gear. After that it is up to her. What you cannot do is protect her from herself. Maybe vaping is a slippery slope to smoke or maybe it isn't. You can't decide that only she can.
