My son is 18 and was in northern michigan when him and 2 of his friends were pulled over for having a headlight out. my son admitted they were smoking marijuana just before being pulled over so when the cop came to the window in smelled the smoke and searched the vehicle. they found about 3.9 ounces of marijuana in 10 different bags and a digital scale. after being arrested the officer told him whoevers marijuana it was would face 4 years in prison if they didnt admit it so he admitted that all the evidence was his. the police then interviewed him for about 2 hours where he wrote down everything and signed it. they did not book him and did not write any tickets they just told him they would contact him in a couple weeks what should i expect? THANKS
