What happens..? You wait. It sometimes takes weeks before charges are filed in court. If you don't get a notice letter from the DA or court in 6-12 months, contact the DA to confirm no charges were or are being filed. Make sure they have your correct address for that letter. If you don't get it and respond, an arrest warrant will be issued. When arrested or charged with any crime, the proper questions are, can any evidence obtained in a test, search or confession be used against you, can you be convicted, and what can you do? Raise all appropriate defenses with whatever witnesses, evidence and sympathies are available for legal arguments, for evidence suppression or other motions, or for trial. If you don't know how to represent yourself effectively against an experienced prosecutor intending to convict, then hire an attorney who does, who will try to get a dismissal, charge reduction, diversion, program, or other decent outcome through plea bargain, or take it to trial if appropriate.
