Skilled Defense Against Driving Under the Influence of Drugs Charges in Corona, CA
California law treats driving under the influence of drugs just as seriously as alcohol-related DUI charges. If you’ve been accused of drugged driving in Corona, CA, you could be facing jail time, fines, license suspension, and a criminal record — even if the drugs involved were legally prescribed or lawfully obtained.
At Liberty Criminal Defense & Immigration, we know how aggressively prosecutors pursue drug DUI charges in Corona, Riverside, San Bernardino, and more. Our experienced Corona drug DUI lawyers focus on identifying weaknesses in the prosecution’s case and providing strategic, results-driven defense tailored to your circumstances.
Whether you were accused of driving under the influence of prescription medication, marijuana, or illegal substances, we are here to defend your rights and your future.
What Is Considered a Drug DUI in California?
Under California Vehicle Code §23152(f), it is illegal to drive a vehicle while under the influence of any drug — whether legal, illegal, over-the-counter, or prescription — if it impairs your ability to operate a vehicle safely.
This means you can be charged with a drug DUI in Corona if:
- A law enforcement officer believes your driving was impaired due to drug use
- You were found with controlled substances or medications in your system
- A Drug Recognition Expert (DRE) determined you exhibited signs of drug impairment
- You failed a field sobriety test and a subsequent chemical test showed drugs in your system
Importantly, California law doesn’t establish a legal limit for most drugs like it does for alcohol. This gives officers broad discretion and makes these cases especially complex — and especially defensible.
Substances Commonly Involved in Drug DUI Charges
Drug DUI charges in Corona can involve a wide range of substances. At Liberty Criminal Defense & Immigration, we’ve defended clients accused of driving under the influence of:
- Marijuana (cannabis)
- Cocaine or crack
- Methamphetamine
- Heroin or opioids
- Xanax, Valium, Ativan, or other benzodiazepines
- Ambien and other sleep aids
- ADHD medications like Adderall or Ritalin
- Prescription painkillers (OxyContin, Vicodin, etc.)
- Over-the-counter medications like antihistamines or cough suppressants
Whether you have a prescription or not, the central issue is whether the drug in question impaired your ability to drive safely. Our Corona drug DUI lawyers build defense strategies that account for your legal rights and the flaws in how impairment is often judged.
Arrested for Drug DUI in Corona? What Happens Next
If you are pulled over in Corona or elsewhere in Riverside County and suspected of drugged driving, the process typically follows these steps:
- Traffic stop and roadside evaluation: An officer may claim to observe signs of impairment such as erratic driving, dilated pupils, or slurred speech.
- Field sobriety tests (FSTs): You may be asked to perform coordination tests that can be highly subjective.
- DRE evaluation: A specially trained officer known as a Drug Recognition Expert may be called in to assess whether you are under the influence of a specific drug class.
- Chemical testing: You may be required to submit to a blood test (there is no breathalyzer equivalent for most drugs).
- Booking and release: You may be booked at a local facility and released with a notice to appear in court.
- DMV and court proceedings: You face a possible license suspension through the DMV and criminal prosecution through Riverside County courts.
Legal guidance at each of these stages is critical. A misstep early in the process can make defending your case more difficult later on.
Unique Challenges in Drug DUI Cases
Unlike alcohol-related DUIs, drug DUIs in California lack clear legal thresholds. Instead, prosecutors must rely on circumstantial evidence and often ambiguous testing to prove impairment.
Here’s where these cases often break down:
- No established limits: There’s no legally defined “safe” level for most drugs in the bloodstream.
- Outdated testing methods: Blood or urine tests can detect drugs long after their impairing effects have worn off.
- Unreliable DRE evaluations: These subjective evaluations are based on interpretation, not hard science.
- False positives: Prescription medications can trigger positive results in drug screens even if you weren’t impaired.
Our Corona drug DUI lawyers know how to challenge the science, the procedure, and the assumptions at the core of these cases.
Legal Penalties for Drug DUI Convictions in Corona
While each case is unique, California imposes serious penalties for a first-time drug DUI conviction:
- Jail time: Up to 6 months in county jail
- Fines: Between $390 and $1,000, plus penalty assessments
- Driver’s license suspension: Up to 6 months (longer for repeat offenses)
- DUI school: 3 to 9 months of education or treatment programs
- Probation: 3 to 5 years of informal probation
- Ignition Interlock Device (IID): May be required depending on the case
Repeat offenses, accidents involving injury, or the presence of minors in the vehicle can significantly increase the severity of your sentence — including felony charges in some cases.
Strategic Defenses Our Attorneys Use
Every drug DUI case in Corona demands a customized defense. At Liberty Criminal Defense & Immigration, we evaluate the evidence from all angles and craft strategies designed to get charges reduced — or dismissed entirely.
Some of the defenses we may raise include:
- No proof of impairment at the time of driving
- Legal use of prescription drugs without impairment
- Improper or unlawful traffic stop
- Inaccurate or mishandled blood test samples
- Improper DRE procedures or flawed interpretation
- Medical or physical conditions mistaken for impairment
We may also work with expert witnesses such as forensic toxicologists or medical professionals to undermine the prosecution’s case and create reasonable doubt.

Frequently Asked Questions About Drug DUI in Corona, CA
Can I be charged with drug DUI if I have a valid prescription?
Yes. Even legally prescribed medications can result in DUI charges if they impair your ability to drive safely. However, a valid prescription may be an important part of your defense.
What is a DRE and how do they affect my case?
A Drug Recognition Expert (DRE) is a police officer trained to detect drug impairment through a series of observations and tests. Their assessments can be challenged as they are not always scientifically reliable.
Do I have to take a blood test for a drug DUI?
If you are lawfully arrested for DUI, refusing a blood test can lead to automatic license suspension and enhanced penalties. However, how the test is conducted and interpreted can be challenged.
Will a drug DUI show up on a background check?
Yes. A conviction will appear on your criminal record unless it is later expunged. That’s why it’s critical to fight these charges from the beginning.
Can I go to jail for a first-time drug DUI in Corona?
Jail is a possibility, though many first-time offenders avoid incarceration with the help of an experienced DUI lawyer.
