Yes. I started vaping to quit smoking, with the eventual goal of being nicotine free entirely. I started with a relatively high level of nicotine, then I started tapering down my nicotine levels. Once I got to the lowest level of nicotine my favorite juices was offed with (besides 0mg) I simply mixed USP VG with my juices to cut them. There was a period that I vaped straight VG just to satisfy the habit once I was down to 0 nicotine, then I quit altogether. I didn't vape or smoke for about a year or so before I went back to cigarettes due in part to stress. Now I'm back to vaping (at 1mg currently). I'm probably going to stay at that level for a while, simply because I enjoy it and I have absolutely zero desire to smoking while I'm vaping. I've just started the journey of DIYing my e-juice and I'm amazed that I can make 30ml of juice for less than $1. If you're on a budget, the start-up cost of buying lots of different flavors, VG/PG, nicotine base, containers, a scale (if you mix by weight - my preferred method now) or graduated cylinders/syringes, but once you've found some recipes you like, it's insanely cheap.
