I don’t really think vaping is a big deal, especially, if you didn’t vape and just were suspended for it. It’s much worse if you smoked. There is an article on smoking on campus https://vapingdaily.com/what-is-vaping/vaping-on-campus/ where I found out most people started smoking after entering the university.
Ive had friends get into good schools with monthlong suspensions. Just write a good explanation about how tou learned from your mistake on the app wheee it gives you space to complain. Also one of my friends did something genius and won a nicotine awareness film fest with her julling psa snd thet just counted her as totally reformed
i had a similar problem with vaping, mine was a little worse though. You will be fine, just make sure you show how you turned around from that mistake and that mistake has made you a better person.
