My own experience is that nicotine calms me, helps me focus, stay focused and gives me the mental pause when my thoughts are running too fast or I just need to zone out for a minute. My vape mod is also something I can fiddle with in my hands, like when I am social situations and feel awkward-don’t know what to do with my hands.
The fact is, all of that, having control over all the aspects of the experience relieves feelings of anxiety for me for which I am very sensitive to.
The ritual involved with the use and care of my vape gear is also soothing. I sure love to vape.
