I'm not sure if I understand your initial question. However, in an investigation, a police agency has the authority to issue supplemental reports based on whatever evidence that they deem appropriate.
After the police agency believes that it has sufficient evidence, it will send the case to the district attorney's office, who will decide whether formal charges will be brought.
Sometimes, the district attorney's office refuses charges submitted to it by police agencies. And, sometimes formal charges are instituted.
With respect to the drug test results, sometimes scientific analysis is necessary to determine the validity of the test (process, sample, and results).
I believe that the arrested person definitely needs to seek out the services of a criminal defense attorney.
