Hmmm, I could do that.
I got into DIY shortly after I started vaping because I read how cheap it can be to make your own e-liquid. I then pushed myself to learn how to rebuild coils out of fear of pending regulations from last year.
I also have been pushing myself towards the zero nicotine level in my mixes. I'm currently in the 2-3mg range. If I should get caught in a nic shortage or the prices skyrocket, then I would quit using nicotine and maybe even vaping too. I would not go back to smoking tobacco EVER! I had already wasted over 40 years trying to quit tobacco to go back after the joys of vaping.
I really enjoy trying to come up with a a new flavor. Maybe I'd take up baking.
