So i got screwed.

i live in NJ and i'm 20. its christmas eve, my bud and i smoked a blunt in my car and then stupidly decided to go to 711, on the way back i made a turn on a yellow and the cop saw and pulled me over (later he said because i made a crooked turn or something). the car reeked, so he asked if theres anything in the car i said no. he began searching, and found the blunt. i then admitted to it and said thats everything. he searched more and didn't find anything. i took the blame and he arrested me, let my friend go and had him follow to the station where he'd wait for me.

i got charged with improper turn, possion of marijuana under 50 grams (its a disorderly persons offense in NJ), and being under the influence controlled dangerous substance.

i kno wi should've just told him straight out that i had the roach, but i was sooo stoned, and a little scared.
any advice? i don't want to tell my parents, and would rather not get a lawyer, i'm thinking of pleading guilty, because the cop told me i probably won't lose my license and to "work with him" that he will try to lower it the best he can.

i've never been in trouble before and am just wondering what will happen. i need my license!
