Replying to Could be going to Jail!! :(

So hanging out with some friends and one of them i didnt know that well, well anyways we decided to go to someones house so he said he would drive us (the guy i dont know to well). so we are driving and get pulled over for suspicious activity. the cop comes up to the car with a gun out and he makes us get out he calss back up and we are all nahdcuffed on the side of the rode wayyy shitty by the way. So the cop found 2 unregistered guns 1600 pills pound of mushies and 2 punds of weed in the trunk. me and my friends had no idea about this and he said they were ours to the cop so right now it says i was in possesion of a forearm and a pound of mushies, so anyways it sucks hope they can prove that i had no idea but im not sure way pissed and super bummed though.
