DUI Drugs and Chemical Testing

Blood testIn order to prove that a driver is under the influence in a Los Angeles DUI case, the police and prosecution rely on the results of chemical testing conducted shortly after the time that an individual was driving. When a driver is suspected of driving under the influence of drugs, the options regarding chemical testing are limited, as there currently are no recognized breath tests that can measure for drug intoxication. It is important to understand how the chemical testing process works when dealing with DUI drug offenses.

The DUI Drugs Arrest Process

When a Los Angeles police officer suspects that a suspect is under the influence of drugs, the officer will often request that a drug recognition expert (“DRE”) officer come to assist in the investigation. DRE officers receive specialized training in recognizing the symptoms of drug intoxication and performing the DRE protocol designed to determine whether or not a DUI suspect is under the influence of drugs. There is currently no breath test that can measure for possible drug intoxication, so DRE officers must look for specific physical symptoms of drug intoxication. Law enforcement agencies are currently experimenting with a mouth swab test that can measure for the presence of certain drugs; and this test is slowly being implemented in the Los Angeles area.

DUI Drugs and the Chemical Testing Process

A person arrested on suspicion of DUI drugs would not be given the testing options provided to DUI alcohol suspects. This is because there is currently no breath test that can measure for the presence or amount of drugs in a person’s system. Instead, the driver would be required to submit to chemical blood testing and the law enforcement agency would have to arrange for a blood draw and analysis of the blood sample.

If the driver refuses to comply with the request for chemical testing, the arresting officer can perform a forced blood draw. Judges are on call and the officer can get a warrant for the blood draw faxed at any point. In these cases, the driver can still be charged with DUI refusal for refusing chemical testing even though there would be BAC or drug panel results when blood test comes back.

The blood sample is sent to the County toxicology lab, which will test for the presence of a panel of legal and illegal drugs that can cause impairment in drivers, including cocaine, heroin, methamphetamine, prescription painkillers, anti-anxiety medication, sleep aids and marijuana.

Blood Test Results and Blood Split Orders

The defendant typically will not learn the results of the blood test until his or her arraignment. If there is a positive test, he or she will be charged with driving under the influence of drugs in violation of California Vehicle Code Section 23152(f) VC.

By law, a portion of the defendant’s blood sample must be preserved. The defense can request a blood split order that would take a testable portion of the blood sample and have it sent to an independent laboratory for retesting at the defendant’s expense. The independent retesting and subsequent review by a toxicologist may reveal that the drug was not found in a sufficient quantity to cause impairment. This is often the case with marijuana, which can remain in a person’s system long after any impairing effect have worn off.

Michael Kraut is outstanding! He genuinely cared about my case and instructed my mom and I throughout the entire process. He was very clear on what he needed in order to receive the best results. He kept us updated until the end. I thank him so much for getting my charges rejected. I highly recommend him to anyone with legal needs! Shaquan
I contacted Michael with concern for my personal and business reputation. He was very reassuring and confident the entire time. After about 3 weeks it was determined that no charges were being filed by any agency and I was in the clear of any investigation. One thing that is amazing is just how FAST Michael is at replying to phone calls, texts, and even emails! We are talking under 30 minutes in most cases. That is unheard of for most attorneys! Michael is incredible and not your typical run of the mill attorney. For best results hire him if you feel like you might be under investigation or could face charges. Even if you know you are innocent it is best to take care of the smoke before it becomes a fire. Brad
Michael Kraut is-hands down-the best criminal defense attorney and I can't begin to thank him for all that he did for me and my family. I reached out to him in the middle of the night and less than a couple hours later, he had gotten back to me and scheduled a meeting. He's a no-nonsense attorney who knows how to get the job done! From the second we retained him, I had peace of mind in knowing that we were in the best hands possible. If Michael Kraut couldn't get it done, I knew that it couldn't be done at all. You can't put a price tag on your freedom. He was worth every single penny. Lida
Michael Kraut is an outstanding attorney. He was extremely professional, and straightforward, yet sensitive with my case. I am confident I made the right choice by hiring Michael. I highly recommend him to anyone seeking a truly experienced lawyer. Daniel
Michael Kraut - I cannot thank you enough for all that you did for ​my son. When I came to you I read that you used to be a district attorney but I never knew how much that meant until I watch you in court. I knew it took 3 months but the final day when I heard the judge say that all charges were dismissed it was all worth it! I will always be grateful for all that you did for us. A.N.
