You must consult a DWI attorney concerning your matter. There may be a legitimate reason for doing only an on-scene alcosensor test, but it alone is not usable at trial, so that creates a problem for them if that is all they have. Your use of medications and narcotics, albeit legal, are not a help, but a reason for you to be prosecuted for DWAI Drugs, and if you gave them statements to this effect, would provide probably cause for the arrest. You need to discuss this with your attorney.
