San Bernardino Marijuana DUI Lawyer

Since the legalization of recreational cannabis in California, marijuana-related DUI arrests in San Bernardino County have surged. Unlike alcohol, where a “0.08%” reading provides a clear legal threshold, there is no scientifically agreed-upon limit for THC impairment. This means a Marijuana DUI arrest is often based entirely on an officer’s subjective opinion, even if you are a legal medical user or consumed cannabis days before driving.

Hart Levin is a former Deputy District Attorney who has seen how these cases are built from the inside. He understands that San Bernardino prosecutors often rely on “junk science” and unreliable observations to secure convictions. At the Law Offices of Hart J. Levin, we use a sophisticated, data-driven defense to challenge the prosecution’s narrative and protect your driving record.

Why Marijuana DUI Cases are Scientifically Flawed

In San Bernardino, law enforcement typically utilizes Drug Recognition Experts (DRE) to evaluate drivers. These officers look for physical signs like red eyes, dilated pupils, or a “slowed” internal clock. However, these signs are not exclusive to marijuana use and can be caused by fatigue, allergies, or the stress of a late-night traffic stop on the I-10 or I-215.

The biggest flaw in the prosecution’s case is the blood test. THC is fat-soluble, meaning it can remain in your system for weeks after your last use. A positive blood test in San Bernardino only proves that you have used marijuana in the recent past; it does not prove you were impaired at the exact moment you were behind the wheel. We work with toxicologists to demonstrate this distinction to the court.

How Former Prosecutor Hart Levin Fights Marijuana DUI Charges

We don’t just accept the lab results. We deconstruct the entire investigation using a former prosecutor’s playbook:

  • Challenging the “Expert” Testimony: We aggressively cross-examine DRE officers on their training and the specific 12-step evaluation process. If they skipped a step or misinterpreted a physical sign, the entire arrest can be called into question.
  • The “Metabolite” Defense: We distinguish between active THC (which suggests recent use) and inactive metabolites. If only metabolites are present, we can prove you were not under the influence while driving.
  • Title 17 Compliance: We ensure the blood draw followed strict California Title 17 regulations. Any contamination or improper storage at the San Bernardino crime lab can make the results inadmissible.
  • Constitutional Violations: If the initial traffic stop lacked probable cause, we file motions to suppress all evidence gathered, which often leads to a complete dismissal of the case.

Protecting Your License and Your Career

In a professional hub like San Bernardino, a DUI conviction (even for marijuana) can trigger a mandatory one-year license suspension and appear on background checks for years. This is especially critical for those in the logistics, medical, or tech industries.

Frequently Asked Questions

Yes. Having a medical recommendation does not grant you immunity from DUI laws. In California, it is illegal to drive while “appreciably impaired” by any substance, regardless of its legal status.

No. Unlike the 0.08% limit for alcohol, California has no “per se” limit for THC. The prosecution must prove that your physical or mental abilities were actually impaired to the point that you could not drive with the caution of a sober person.

If you are convicted or if you lose your DMV administrative hearing, your license will be suspended. However, by requesting a hearing within 10 days of your arrest, we can often secure a “Stay” on the suspension while we fight the case.

A DRE is an officer who has completed a specific course on identifying drug impairment. While they are often treated as experts in San Bernardino courts, their conclusions are often based on subjective observations that we can challenge with medical evidence.
