In DUI cases that involve drugs, accurate testing is critical. You may have concerns about the accuracy of the tests used in your case and if it’s possible skewed results could have a negative impact on your future. It is your right to challenge any evidence used against you. You may find it helpful to learn more about the most common methods used for testing and how the tests work.

A closer look at drug testing 

Law enforcement can stop a driver for suspected intoxicated driving. While a Breathalyzer test can determine a person’s blood alcohol content, it cannot accurately detect a person’s level of impairment if police suspect he or she is under the influence of drugs. A drug test may be necessary. There are different types of drug tests, and typically, they run a panel to see if one of several drugs is in a person’s system.

In most cases, a drug panel requires a urine sample, but in some cases, a blood test is appropriate. The companies that produce these tests claim they are accurate. However, it is possible any of the following factors could impact the results of a drug test:

  • Consumption of medications prescribed by a doctor
  • Mishandling of blood sample or chain of custody problems
  • Problems with the administration of the test
  • An inexperienced individual administering the test

You are entitled to a defense, and as part of this strategy, you may want to challenge the results of your drug test. The charges against you are serious, and the implications are grave. However, a strong defense may allow you to avoid a conviction or mitigate some of the penalties you are facing.
