I don’t get the difference

So I vape, big whoop. I used to only vape at a 3 or 6 nic. Suddenly I went up to a 30 or 50 nic because my boyfriend and I hang out, and he vapes a 50 nic (I’m 20 so I can’t buy juice yet). My brother vapes 30 nic. My best friend also vapes, but only at a 3 nic. When I told her “damn, I can’t feel this anymore”. She automatically starts attacking me with “well maybe you shouldn’t be vaping 50’s and you could feel this. You’re addicted, you need to go down.” W-what? Excuse me? Alright fine, maybe you can consider me addicted, but I can go without. I’ve done it before when I’ve run out of juice, and it’s never bothered me. You could say the same with caffeine. I complain about being tired and needing it, and I’d get “girl same, we should go get some.” The stigma around addiction with nic and caffeine is so annoying tbh. She drinks about 3 Red Bull’s a day plus coffee, but wants to get on me about my little comment on not being able to feel nic...?

It’s all just stupid addiction mumble lol I can go without both, but I choose not to because... well... it’s my life?
