Naw man its fine when i got caught with weed the letter said that and you just go talk to a probation officer. and you can say if you want to bring it into court and get a lawyer and stuff but its usually not worth it for little things. You will probably just have to do some community service or a vandalism prevention class or somthing of that sort and they wont put it on your record. Its chill dont worry about it.
Peace
