i think u can have a free session with a lawyer discussing your case first b4 hiring him to see if u stand a chance... it appears u have let them in with consent and told them yourself about the stuff

and u said they ONLY charged u with paraphernalia & simple possession, so there seems to be no intent to distribute or conspiracy to do so charges, right?

talk to a lawyer and see what are your chances... maybe the lawyer can at least work out a deal or something even if u stand minimal chances, idk, have never been in such a situation.
