The drug has to be from the family of drugs that the DRE officer determined during his or her observation was the source of impairment. There are seven families. So it is not anything we find...because believe me, we're very good at finding very minute amounts of drugs in our laboratories. What we're concentrating on is confirmation. If the police officer, the DRE, thought it was a particular type of drug that was causing the impairment, that is what we will confirm or invalidate, if that is the case. It's very objective.
