i think you can get out of this one. it doesn't matter that they didn't read you your rights they only do tht on t.v , ive been arrested 3 times and never heard anything about my rights from the cops. call normal ask them for advise. you weren't high and you didn't have any weed, why did they pull you over and search, it sounds like unlawful search and stuff. tell them you got high at a party 4 days ago to explain thc in blood but i bet prosocution will will drop the case. lol
