i had 1 sip of redbull in high school, and have tried friends’ vapes like 2ish times but that’s it! it originally was because of the substance/ caffeine level itself because of the fearmongering in school as a kid (justified reasoning, wrong approach)
then in college i drank lots of coffee and partied a bunch and smoked the occasional cig and was fine, so my thinking evolved to seeing it as just kind of ridiculous… i think if you’re going to consume caffeine or nicotine just have coffee/ tea or a cig like god intended. to me, vape = nicotine pacifier
