Law enforcement may test a driver for drug intoxication using several different methods. An officer could potentially use a DRE (drug recognition expert) while on the street, using a 13-step process carried out by a qualified officer. However, most tests are conducted using a sample of the driver’s blood. Law enforcement will obtain this sample through consent or by warrant.
After it goes to the lab, the lab will offer a report whose results will go directly to the officer who made the arrest. It is important to recognize that an individual does have the right to refuse a breath or blood test in the state of Texas. However, there are consequences that can follow this refusal such as the suspension of one’s driver’s license.
