Generally speaking, it is more difficult to prove drugged driving than drunk driving when relying on lab testing alone. Alcohol’s effects on the body and the testing for impairment are a lot better established than those of many drugs. That said, every drunk/drugged accident case has its own facts and circumstances, and test results constitute only one portion of the evidence typically available to prove someone’s liability. Speak with an experienced car accident injury attorney right away if the other driver in your accident seemed drunk, high, or otherwise impaired.
