you were smoking weed-illegal
smoking while driving-illegal
failed to stop at a stop sign-illegal
all factors point to you being a fuckin moron. not because you got caught, but your reasoning, justification, and rationalization are that of a 15 year old. im not saying this to be a dick, but i was in a similar position when i was 16. 2 misdemeanor charges, but they set my bail at 15gs, 3months-1year, and 3-5years probation. after i did a week in jail, month in rehab,and year of probation they took away all my charges, cleared all my points on my drivers license, and only gave me a year probation only once a month. however, i had a truly dickhead cop, who decided to try to intimidate me with guns, and once he realized that wasnt working punched my in the balls and smashed me head against a brick wall...
maybe shit will work out in your favor.
