You should really hire an attorney, if you're able:
1. There could be a constitutional violation with respect to the search of your car.
2. Field testing for drugs is very unreliable, and from the sound of it, the officer had no idea what the substance was.
There could be other issues with the case an experienced attorney can leverage in an attempt to resolve the case in your favor.
Feel free to contact me if you have more specific questions.
Best,
Rick
