It seems (or at least around here) schools and cops can get away with anything they want to.
Just consider it lucky that you know what days the dogs are coming.
You know it's fucked up when the school cop shows up to your house and tells you that you can be suspended/expelled for things you said on the internet to your girlfriend about drugs. Luckily I never got suspended or expelled but lately those motherfuckers have been watching me like crazy...
Though I seriously doubt that they're going to search you, as like go through your pockets and shit. That'd take too long and usually when the dogs come to my school they're in and out in less than 45 minutes.
but...
if someone wants to bring something to school to give to you, tell them to wait until the end of the day. have them put it in their pocket and give it to you in the hall after the last class. even if someone snitches, by the time you leave the school cops or the principal won't have enough time to get you and unless it's on camera they can't do shit.
i have no idea where the fuck i went with this, i think i need to slow down on the adderall.
but yeah don't get caught man, my girlfriend was expelled a month or two back and got arrested and charged with a felony, distribution of a controlled substance for giving a few people tramadol.
