Nicotine free options

Hello, I just recently turned 21 and I’m looking for a quality, nicotine free, vape option. I know it sounds backwards as I’ve never really smoked a day in my life. I was always around people who smoke/ vape in closed spaces. I feel terrible when I find my mouth watering over a vape or a cigarette and don’t want to actually smoke nicotine. But I find myself craving that hand to mouth connection. Is there such a thing as a fruity flavored nicotine free vape option? I’d love one that is thin and not boxy and re-usable if applicable. I just don’t wanna have to spend on ton on disposable ones and make waste but if that’s the only option I get it. Are there pen kits I could buy? I just need some help. Thank you:3
