San Bernardino Drug DUI Lawyer

A DUI arrest in San Bernardino County does not always involve alcohol. Under California Vehicle Code 23152(f), it is illegal to drive while under the influence of any drug, including legal marijuana, prescription medications, and over-the-counter drugs. Because there is no “legal limit” for drugs like there is for alcohol, these cases are highly subjective and rely heavily on the personal opinion of the arresting officer.

Hart Levin is a former Deputy District Attorney who has prosecuted thousands of cases. He knows that DUID charges in San Bernardino (whether they originate from a stop on the I-10 or a patrol in Rancho Cucamonga) are often based on flawed science and weak observations. At the Law Offices of Hart J. Levin, we use our insider knowledge of the prosecution’s tactics to dismantle these claims and protect your future.

Why Drug DUI Cases Are Different in San Bernardino

Unlike an alcohol DUI where a breathalyzer provides a specific number, drug DUI cases are built on a “totality of the circumstances.” The District Attorney typically relies on a Drug Recognition Expert (DRE) (a police officer with specialized training) to testify that you were impaired. However, the signs they look for, such as dilated pupils or a rapid heart rate, can often be explained by anxiety, medical conditions, or even the stress of being pulled over.

Our firm challenges every aspect of the DRE’s evaluation. We investigate whether the officer followed the mandatory 12-step evaluation process and we scrutinize the blood test results for errors. In 2026, California’s DUID laws have become increasingly complex, making it essential to have a lawyer who understands the chemical and legal nuances of these “invisible” injuries.

Common Substances Involved in San Bernardino DUID Arrests

We provide an aggressive defense for individuals charged with driving under the influence of various substances, including:

  • Marijuana: Even though it is legal in California, you can be charged with a DUI if an officer believes your driving is impaired by THC.
  • Prescription Medications: Common drugs for anxiety (Xanax), pain (Oxycontin), or even sleep aids (Ambien) can lead to a DUID arrest if they are found in your system.
  • Illegal Narcotics: We defend cases involving cocaine, methamphetamine, and other controlled substances where the penalties can be much more severe.
  • Over-the-Counter Meds: Something as simple as a powerful allergy medication or cold medicine can impair your motor skills enough for an officer to make an arrest.

How Former Prosecutor Hart Levin Fights Your Drug DUI

When your career and driving privileges are on the line, you need a defense that goes beyond the basics. Hart Levin’s experience on the “other side” of the courtroom allows him to identify the specific vulnerabilities in the prosecution’s case:

  • Attacking the “Expert” Testimony: We cross-examine DRE officers to show that their conclusions are subjective and not supported by the medical facts.
  • Blood Test Defenses: We look for “fermentation” in blood samples or improper storage techniques that can lead to false positives or inaccurate levels of a drug in your system.
  • Challenging the Initial Stop: If the officer did not have a valid, constitutional reason to pull you over, we can move to have all evidence—including your blood test—thrown out of court.
  • Alternative Explanations: We work with medical experts to provide alternative reasons for your physical appearance or performance on field sobriety tests, such as fatigue or pre-existing health issues.

Yes. Just like an alcohol DUI, you have only 10 days from the date of your arrest to request a hearing with the DMV. However, the DMV’s authority in drug cases is different, and having an attorney who understands these distinctions is critical to saving your license.

The penalties are largely the same as an alcohol DUI, including heavy fines, mandatory drug education programs, and a potential driver’s license suspension. However, in 2026, new laws have increased the probation periods for many of these offenses to three to five years.
