How do I convince my mom to change her mind?

dont tell her to f*ck off, because thats not going to fix anything as for you, you did drugs thats a pretty big and bad thing to do, especially at your age because there are so many things that could have went wrong (they do kill people by the way) and its so easy for other people to take advantage of you when your not thinking clearly so I assume that whatever trust you mum had for you is now broken and she probably feels like your getting out of control and might think the drugs you took could turn into a habbit so she wants to get it sorted out, and you cant blame her for caring because if she didnt care, she wouldnt have tried to do anything about it if you feel like you dont need to go, have learned your lesson and wont touch drugs again talk to your mum about this when shes in a calm mood maybe even ask if you could both talk to a counsellor about it so you can both get your point accross otherwise, you need to understand that your 13, and are living under her house and under her rules and even if you dont like it, it might be best to be taught about why drugs are so bad and why at your age you shouldnt touch them though I wouldnt suggest a rehibilitation boot camp because it doesnt sound like your using them all the time or are addicted so maybe talk to your mum about some other kind of punnishment that would not be as harsh but would teach you about why what you did was wrong also, doing drugs at your age does deserve a punnishment of some kind so dont expect much sympathy from your mum, even if your birthdays comming up
