Welcome to the forum. While I agree with the others and believe it is probably smarter to not vape nic, I don't fault anyone for vaping juice with nic in it. Some people, like myself, enjoy the nicotine. Just be sure you know the potential risks associated with it. Is it potentially addictive? Yep. Then again, so is alcohol, but I doubt most people rush out to buy a 30 pack of non-alcoholic beer for their 21st birthday(I know I sure didn't. I celebrated with everyone in my house doing power hours, with me being the one changing it up and instead of just doing a shot of beer every minute, I made it a shot of vodka every 10th minute. I really don't remember how much I puked that night, but I know it was fun as far as I remember.). We all do things for our own reasons, and I see no reason to belittle anyone over their choice of what they do in their life.
When it all comes down to it, do what you like. It is your health and your life. If you want to take the chance on becoming addicted to nicotine, that is your choice. Being addicted to it isn't a good thing, but there are a lot worse things you could be getting hooked on. Just do your own thing and be sensible about it.
Welcome to the club. Enjoy your new obsession. Hopefully you have a spare room in your house for when your collection grows.
