California has no legal limit for THC the way it sets 0.08% for alcohol — and that single fact is the reason so many drug DUI cases fall apart under pressure. If you were arrested for driving under the influence of marijuana, prescription medication, or any drug in Los Angeles, the prosecution has to prove your driving was actually impaired, not just that a substance showed up in your blood. That gap is where a real defense lives. At Chudnovsky Law, our team brings together more than 113 years of combined courtroom experience and over 9,000 cases handled, including former prosecutors who know exactly how these cases are built.
You have only 10 days from your arrest to request a DMV hearing — miss it and your license is automatically suspended. Chudnovsky Law defends DUID clients across Los Angeles County, from the Clara Shortridge Foltz Criminal Justice Center downtown to courtrooms near LAX. Our attorneys hold a 10.0 Superb rating on AVVO and 5-star reviews across Google. Call (213) 212-5002 now for a free, confidential consultation — we answer 24/7.

What Counts as a Drug DUI (DUID) Under California Law?
A drug DUI in California means operating a vehicle while your mental or physical abilities are impaired by any drug — legal, illegal, prescription, or over-the-counter — to a degree that you can't drive with the caution of a sober person. It's charged under Cal. Vehicle Code § 23152(a), the same statute that covers alcohol impairment.
Here's what catches most people off guard: there's no per-se limit for drugs. With alcohol, a 0.08% blood reading is enough to convict under Cal. Vehicle Code § 23152(b). Drugs don't work that way.
DUID stands for "driving under the influence of drugs." Unlike alcohol cases, there is no specific blood concentration that automatically proves guilt — the prosecution must show your driving was genuinely impaired by the substance.
That distinction matters enormously. THC can linger in your blood for days or even weeks after the high wears off, especially for regular cannabis users. A blood test showing active THC tells a jury almost nothing about whether you were impaired the moment you were pulled over on the 101 or the 405.
As a former Deputy District Attorney who prosecuted these exact cases, Kareem Aref understands how thin the science often is. He knows prosecutors lean heavily on officer observations and the testimony of a Drug Recognition Expert (DRE) — a police officer trained in a 12-step protocol to identify drug impairment — because the lab numbers alone rarely close the gap. That insider knowledge shapes how we attack these cases from day one.
The core weakness in nearly every drug DUI prosecution is the disconnect between a drug being present in your body and that drug actually impairing your driving. We build the defense in that space.
Worried this all sounds overwhelming? That's exactly what a free consultation is for. No pressure, no obligation — just honest answers about where you stand.
What Are the Real Penalties for a Drug DUI in Los Angeles?
A first-offense misdemeanor drug DUI in California carries up to 6 months in county jail, fines and penalty assessments that can exceed $2,000, a 6-month license suspension, and a mandated DUI education program lasting 3 to 9 months. Second and third offenses raise the jail exposure to up to 1 year under Cal. Vehicle Code § 23152(a).
But the courtroom sentence is only part of the damage.
Approximately 1.0 million people are arrested for driving under the influence annually (FBI Uniform Crime Report, 2022), and the financial fallout is steep. The average DUI costs the defendant between $10,000 and $15,000 once you account for fines, legal fees, insurance hikes, and lost time (National Highway Traffic Safety Administration, 2023).
When a Drug DUI Becomes a Felony
A drug DUI crosses into felony territory in specific situations. If your impaired driving causes injury to another person, you can be charged under Cal. Vehicle Code § 23153 — a wobbler that can be filed as a misdemeanor or felony. As a felony, it carries 16 months, 2, or 3 years, with additional time added per injured victim and for great bodily injury.
A fourth DUI within 10 years becomes a felony under Cal. Vehicle Code § 23550, punishable by 16 months, 2, or 3 years. A current DUI is also a felony if you have a prior felony DUI conviction under Cal. Vehicle Code § 23550.5.
The Collateral Consequences Nobody Warns You About
A DUID conviction can cost you a professional license, a security clearance, or a job that requires driving. For immigrants, certain drug-related convictions trigger immigration consequences under federal law. For licensed professionals — nurses, doctors, pharmacists, contractors — a conviction can spark a separate disciplinary investigation. Our firm also includes attorneys who defend professional licenses, so we see the full picture of what's at stake.
13,524 people died in alcohol-impaired driving crashes, accounting for 32% of all traffic fatalities (NHTSA, 2022) — and prosecutors carry that public-safety weight into every DUI courtroom, drug cases included. They treat these charges seriously. So should your defense.
Don't wait on this. The 10-day DMV deadline doesn't pause while you think it over. Call (213) 212-5002 to protect your license before the clock runs out.
How Does Chudnovsky Law Defend Drug DUI Cases?
We defend drug DUI cases using what we call the DUID Pressure-Point Method — a four-stage approach built from decades of watching how prosecutors assemble and weaken these cases from the inside. Each stage targets a specific vulnerability in the state's evidence.
Stage 1 — The Stop. Every drug DUI starts with a traffic stop, and that stop must be legal. Under the Fourth Amendment, police need reasonable suspicion to pull you over. We pull dispatch logs, dashcam footage, and the officer's report to test whether the stop holds up. If the stop was unlawful, everything that follows can be suppressed.
Stage 2 — The Observations. Drug DUI convictions lean heavily on what the officer claims to have seen. As a former prosecutor, Kareem Aref knows the weak observation reports always look the same — vague, conclusory, copied from a template. We cross-examine those observations against the bodycam reality.
Stage 3 — The Science. This is where drug cases break. We bring in toxicology challenges: blood draw timing, sample storage, lab calibration, and the meaning of a THC number that doesn't correlate to impairment. Field sobriety tests — standardized roadside exercises like the walk-and-turn — were validated for alcohol, not drugs, and we make juries understand that distinction.
Stage 4 — The Use. With the weaknesses mapped, we push for reductions, dismissals where the evidence is thin, or a wet reckless plea under Cal. Vehicle Code § 23103.5 — a lesser charge carrying up to 90 days in county jail instead of a full DUI.
Our goal at every stage is to eliminate or weaken the prosecution's proof of impairment before the case ever reaches a jury. With over 9,000 cases behind us and Kareem Aref's prosecution background guiding strategy, we know which pressure points actually move a case.
One note on diversion: many people assume a clean record makes them eligible for misdemeanor diversion. For DUI, that door is closed. Under Cal. Vehicle Code § 23640, DUI offenses are categorically barred from misdemeanor diversion — a point confirmed by the appellate courts in Grassi v. Superior Court (2021) and Tan v. Superior Court (2022). Anyone promising you "diversion" on a DUI doesn't understand the law. We tell you the truth instead.

What's Different About Marijuana DUI vs. Prescription Drug DUI?
Marijuana DUI and prescription drug DUI cases share a courtroom but break down very differently under the science. The shared weakness — no per-se limit and a poor correlation between blood levels and impairment — plays out in distinct ways for each.
Marijuana DUI in Los Angeles
A marijuana DUI conviction requires proof that THC actually impaired your driving, not merely that THC was present in your blood. This is the single most important fact in any cannabis DUI defense.
THC is fat-soluble. It stores in your body and releases slowly, which means a daily or weekly cannabis user can test positive days after their last use, long after any impairing effect is gone. Prosecutors know this, which is why they rely so heavily on DRE evaluations and roadside observations.
How long does THC stay detectable in a blood test? Active THC can remain measurable in blood for hours to several days, and in chronic users, sometimes longer. Because of this, a positive blood result alone does not establish you were impaired at the time of driving. We use this scientific reality to dismantle the state's impairment narrative.
Legal cannabis use makes no difference to a DUI charge. Buying legally at a licensed Los Angeles dispensary doesn't give you a defense — driving impaired is still driving impaired. But the proof requirement remains the prosecution's burden.
Prescription Drug DUI in Los Angeles
You can be convicted of DUI for driving on a medication your doctor legally prescribed — including Ambien, Xanax, opioid painkillers, Adderall, and many others. A valid prescription is not a defense if the drug impaired your driving.
Can I get a DUI from medication my doctor prescribed? Yes. California law makes no exception for legally prescribed drugs. If the medication impaired your ability to drive safely, you can be charged under Vehicle Code § 23152(a), even with a valid prescription and even at the prescribed dose.
That said, prescription cases come with defenses that marijuana cases don't. Many people experience zero impairment at a therapeutic dose. Some medications produce symptoms — drowsiness, slowed speech — that mimic impairment but stem from the underlying medical condition, not the drug. We work with medical experts to separate the two.
Polydrug and Combination Cases
Cases involving alcohol plus a drug, or multiple drugs, are charged more aggressively and require careful toxicology work. The interaction effects prosecutors allege are often overstated. We scrutinize every assumption in those reports.
Here's what most people miss: the more complex the toxicology, the more places it can go wrong. Complexity cuts both ways, and we use it for the defense.
Drug DUI Outcomes: Trial vs. Plea vs. Reduction
Every case is different, but understanding the realistic paths helps you make informed decisions. The table below compares common resolutions in Los Angeles drug DUI cases. These are general scenarios, not promises — your actual options depend on the evidence.
| Resolution Path | Typical Custody Exposure | License Impact | Long-Term Record |
|---|---|---|---|
| Full DUI Conviction (1st, misdemeanor) | Up to 6 months county jail | 6-month suspension | Priorable DUI for 10 years |
| Wet Reckless (VC 23103.5) | Up to 90 days county jail | Often no mandatory suspension | Still priorable; lesser stigma |
| Reduction to Dry Reckless | Up to 90 days county jail | No DUI suspension | Not a priorable DUI |
| Dismissal (weak impairment proof) | None | DMV action still possible | No criminal conviction |
| Acquittal at Trial | None | DMV action separate | No conviction |
The criminal court case and the DMV license action run on two separate tracks — winning one does not automatically resolve the other. That's why the 10-day DMV hearing request is so urgent and so easy to miss. We handle both fronts.
Key insight: In our experience, drug DUI cases are more often reduced or dismissed than alcohol cases, precisely because the impairment proof is harder for the state to lock down. A THC number that means nothing to a toxicologist still has to be explained to a jury, and that explanation frequently collapses under cross-examination.

Defending Drug DUI Cases in Los Angeles County Courts
Los Angeles County handles tens of thousands of criminal cases each year, and drug DUI cases move through specific venues depending on where you were arrested and whether the charge is a misdemeanor or felony.
Which Court Will Hear My Drug DUI Case?
For arrests in central and downtown Los Angeles, misdemeanor drug DUI cases are typically heard at the Metropolitan Courthouse at 1945 S. Hill Street. Felony drug DUI matters — those involving injury or prior felony DUIs — generally go to the Clara Shortridge Foltz Criminal Justice Center at 210 W. Temple Street, the primary felony courthouse for the central district.
Arrests on the westside, near LAX and the 405 corridor, often route to the Airport Courthouse at 11701 S. La Cienega Boulevard. Cases from the eastern part of the county may be heard at the East Los Angeles Courthouse on Civic Center Way. Knowing the local rhythm of each courthouse — how its prosecutors approach drug cases, how its judges handle toxicology disputes — matters in negotiation.
Local Patterns We See
LA drug DUI stops cluster on the major arteries — the 101 through downtown, the 405 through the Westside, the 10 heading east. Late-night stops near entertainment districts and after dispensary closing hours generate a heavy share of marijuana DUID arrests. After a blood draw, samples typically run through county or contract toxicology labs, and turnaround times create gaps we examine closely.
The California DMV administers the license suspension side, while the Los Angeles County District Attorney prosecutes the criminal charge. These are separate processes with separate deadlines, and missing either one carries real cost.
What most people miss: the officer who arrests you for drug DUI is frequently not a trained Drug Recognition Expert, and the DRE evaluation may happen later, at the station, under conditions a defense attorney can challenge. The chain from stop to blood draw to lab report has multiple links, and each one is a potential break point.

Frequently Asked Questions
Is there a legal THC limit for driving in California?
No. California does not set a per-se THC limit the way it sets 0.08% for alcohol. To convict you of a marijuana DUI, prosecutors must prove your driving was actually impaired by THC, not just that THC was present in your blood. This proof gap is the central weakness in most cannabis DUI cases, and it's where a strong defense begins.
Can I get a DUI for taking my prescription medication?
Yes. California law makes no exception for legally prescribed drugs. If a medication like Ambien, Xanax, an opioid, or Adderall impaired your driving, you can be charged under Vehicle Code § 23152(a) even with a valid prescription at the prescribed dose. Having a prescription is not a defense, but many people show no real impairment at therapeutic doses, which we can demonstrate.
How long do I have to save my driver's license after a drug DUI arrest?
You have only 10 days from the date of arrest to request a DMV hearing. Miss that deadline and your license is automatically suspended. The DMV process is completely separate from your criminal court case, so winning in court doesn't fix the DMV side. Call a lawyer immediately so this window doesn't close on you.
How much does a drug DUI lawyer cost in Los Angeles?
Your first consultation is free. Many drug DUI cases are handled on a flat fee, so you know the total cost before you retain us, and we offer payment plans. The exact fee depends on whether your case is a misdemeanor or felony and how complex the toxicology is. We discuss all of this transparently during your free call at (213) 212-5002.
How long does THC stay in your blood after using marijuana?
Active THC can stay measurable in blood for hours to several days, and in regular or chronic users, sometimes longer because THC is stored in body fat. This means a positive blood test alone does not prove you were impaired when you were driving. We use this scientific reality to challenge the prosecution's impairment claim.
Can a marijuana DUI charge be reduced or dismissed?
Many drug DUI cases are reduced or dismissed because impairment is hard for the state to prove. Possible outcomes include a wet reckless under Vehicle Code § 23103.5, a reduction to dry reckless, or dismissal when the impairment evidence is thin. We can't promise a specific result, but we pursue every reduction and dismissal the evidence supports.
Will I go to jail for a first-offense drug DUI?
A first-offense misdemeanor drug DUI carries up to 6 months in county jail, but many first offenders avoid custody through probation, DUI education programs, and other alternatives. Jail becomes far more likely with injuries, prior offenses, or felony charges. The specific outcome depends on the facts, your record, and the strength of your defense.
What is a Drug Recognition Expert and can their evaluation be challenged?
A Drug Recognition Expert (DRE) is a police officer trained in a 12-step protocol to identify drug impairment. Prosecutors rely on DRE testimony because blood numbers alone rarely prove impairment. DRE evaluations are absolutely challengeable — we examine the officer's training, the conditions of the evaluation, and whether their conclusions match the bodycam evidence.
Does a drug DUI go on my permanent record?
A drug DUI conviction stays on your criminal record and counts as a priorable DUI for 10 years, meaning a later DUI is treated as a repeat offense. It can affect employment, professional licenses, and immigration status. In many cases, a conviction may later be eligible for expungement under Penal Code § 1203.4, which we can discuss with you.
Can I be charged with DUI if I only used legal cannabis from a dispensary?
Yes. Buying cannabis legally from a licensed Los Angeles dispensary gives you no defense to a DUI charge. The legality of your purchase is irrelevant — what matters is whether you were impaired while driving. The prosecution still has to prove that impairment, which remains their burden in every case.
