I'm afraid of getting beat up for snitching on someone who is vaping what should I do

It's important to prioritize your safety in any situation. If you feel at risk of being physically harmed for reporting someone for vaping, it may be best to find alternative ways to address the issue. You could consider speaking to a trusted adult or authority figure, such as a teacher or school counselor, who can intervene and address the situation without putting you at risk. It's important to remember that your safety is the top priority, and there are always ways to address issues without putting yourself in harm's way.
