He gave me a sobriety test and arrested me for DUI. At the station I blew a 0.0 and a DRA gave me a variety of tests and took a urine sample. I got a ticket for DUI, not pulling to the right and not staying in my lane. The DRA said I was under the influence of K2 or spice (synthetic marijurana) My urine test came back clean. I have two prior DUI on my record in NJ. This would be my third. I was not under influence of anything, I stayed my lane because I saw the cop and I pulled to the right when the light went on . I had a shoe box in my car with tobacco and rolling papers. I role my own tobacco. The cop looked opened the shoe box, maybe he thought that was k2 or spice. Does any lawyer have any advice for me as to a defence? I would really appreciate it.
