for yourself..IF the cop didnt give you a drug test to determine if the chemical was in your body..there is no way a ticket can stand up in court..
remember the court has to PROVE you where high at the time you operated a vehichle..this will be very hard to do unless you were taken into custody, and had extensive testing done almost immediately....to be safe clean out and fight that ticket...most states punish for operating a motor vehichle while under the influence of drugs/narcotics just as if you were drunk....when is the last time you got stopped while drunk and then let go?
good luck
