What should I do if I was broken down in my car hood up when arrested for DUI, no alcohol, and was put in jail?

The consequences for a drug DUI are the same as those of an alcohol DUI. However, drug DUIs are much harder to prove, because there isn't a specific concentration that the state deems as impairment. With that said, you need to hire a DUI specialist, because by yourself the prosecutor simply won't budge.
