Driving Under the Influence of Drugs in California

Posted by John Campanella | Jan 03, 2025 | 0 Comments

Driving under the influence of drugs (DUID) is a growing concern in California. As an experienced DUI attorney since 1994, I've seen firsthand how these cases unfold and the serious consequences they bring. Whether it's a prescription medication, recreational drug, or something over the counter, driving while impaired can lead to severe penalties and life-altering consequences.

At The Law Office of John Campanella, I'm here to guide you through this challenging time. Let's dive into what you need to know about DUID laws in California.


What Counts as Drug-Impaired Driving?

California law prohibits driving while under the influence of any substance that affects your ability to operate a vehicle safely. This includes:

  • Illegal drugs like marijuana (even if it's legal to use recreationally), cocaine, or methamphetamine.
  • Prescription drugs like painkillers or sleep aids that impair focus or motor skills.
  • Over-the-counter medications such as allergy or cold medicines that cause drowsiness.

Important to Remember: Even if you have a valid prescription, you can still face DUID charges if the medication affects your driving ability.


How Are DUIDs Detected?

Unlike alcohol-related DUIs, which can be measured with a breathalyzer, detecting drug impairment relies on other methods:

  • Field Sobriety Tests (FSTs): Officers assess coordination, balance, and attention.
  • Drug Recognition Experts (DREs): These specially trained officers evaluate whether a driver is impaired by drugs.
  • Chemical Tests: Blood or urine samples are used to confirm the presence of drugs in your system.

What Are the Penalties for DUID in California?

First Offense:

  • Fines: $390–$1,000, plus additional court costs.
  • License suspension for up to 6 months.
  • Mandatory attendance in a DUI education program.
  • Jail time of up to 6 months.

Subsequent Offenses or Aggravating Factors:

  • Increased fines and penalties.
  • Longer license suspension or even permanent revocation.
  • Lengthier DUI programs.
  • More jail time—up to 1 year or longer if someone was injured.

A DUID conviction stays on your criminal record and can affect your employment, housing, and personal reputation.


Why You Need an Experienced DUI Defense Attorney

DUID cases can be complex. Unlike alcohol-related DUIs, which rely on clear legal limits like a blood alcohol content of 0.08%, drug impairment is more subjective. An experienced attorney like myself can:

  • Challenge field sobriety and chemical test results.
  • Question the qualifications of the arresting officer or DRE.
  • Negotiate to reduce or dismiss charges when possible.

Since 1994, I've been defending clients in DUI and DUID cases across California. I know the strategies that work and how to protect your rights in court.
