California drug courts offer some defendants an alternative approach to the traditional criminal justice process by combining court supervision with substance-use treatment and other rehabilitative services. Drug court is not the same as drug diversion, and eligibility, requirements, and outcomes can vary depending on the county, the charges, and the defendant’s history.
California has used treatment-oriented court programs for decades to address criminal cases in which substance use is a significant underlying issue.
Today, adult drug courts are part of California’s broader collaborative justice court system.
Rather than focusing exclusively on punishment, these programs can combine judicial supervision, treatment, testing, probation supervision, and other services intended to address substance-use disorders and reduce future criminal activity.
What Is Drug Court in California?
Drug court is a specialized court program designed for defendants whose substance-use problems have contributed to their involvement in the criminal justice system.
California’s drug courts are collaborative courts, sometimes called problem-solving courts.
Depending on the particular program, the drug court team may involve:
- A judge
- Prosecutors
- Defense attorneys
- Probation officers
- Substance-use treatment providers
- Mental-health professionals
- Other community service providers
The goal is generally to combine accountability with structured treatment and close supervision.
How Does Drug Court Work?
Drug court procedures vary from one jurisdiction to another.
Most adult drug courts in California use a post-adjudication model. This means a participant may enter drug court after entering a guilty or no-contest plea.
Other programs can use diversion or pre-plea models that do not require an initial guilty plea.
Because these models have very different legal consequences, it is important to understand the specific program being offered before agreeing to participate.
What Happens While You Are in Drug Court?
Drug court is typically more intensive than ordinary probation.
Requirements vary by program but can include:
- Substance-use treatment
- Regular drug or alcohol testing
- Frequent court appearances
- Meetings with probation or program staff
- Individual or group counseling
- Mental-health treatment when appropriate
- Education or employment requirements
- Recovery-related activities
- Compliance with other court-ordered conditions
Participants generally return to court periodically so the judge and treatment team can evaluate their progress.
Programs may use incentives for progress and graduated responses when participants fail to comply with program requirements.
Who Qualifies for Drug Court?
There is no single statewide eligibility rule that applies identically to every California drug court.
Eligibility can depend on factors such as:
- The charges filed against the defendant
- The defendant’s criminal history
- The relationship between substance use and the alleged criminal conduct
- The defendant’s treatment needs
- Public-safety considerations
- The eligibility requirements of the local drug court program
- The defendant’s willingness and ability to participate in treatment
Some programs are designed for defendants considered to have a high risk of reoffending and a significant need for substance-use treatment.
The fact that someone has been charged with a drug offense does not automatically mean that person qualifies for drug court.
Likewise, drug court may sometimes be available in cases involving offenses other than simple drug possession when substance use contributed significantly to the criminal conduct.
Is Drug Court the Same as Penal Code 1000 Drug Diversion?
No.
Although both can involve treatment, drug court and Penal Code section 1000 diversion are different legal mechanisms.
Penal Code section 1000 provides pretrial diversion for certain qualifying drug offenses and eligible defendants. Successful completion can result in dismissal without a conviction on the diverted charge.
Drug court, by contrast, is a collaborative court program. Many adult drug courts operate after a defendant has entered a plea, although some jurisdictions have pre-plea or diversion models.
For a detailed explanation of California’s current diversion laws, see our guide to California drug diversion programs.
What Was California’s Original Proposition 36?
The name “Proposition 36” can now cause considerable confusion in California drug cases because two different ballot measures have used that number.
California voters approved the original Proposition 36, known as the Substance Abuse and Crime Prevention Act, in 2000.
That law created a treatment-oriented probation framework for qualifying people convicted of certain nonviolent drug-possession offenses.
The original Proposition 36 provisions remain part of California law, including provisions found in Penal Code sections 1210 and 1210.1.
However, this law should not be confused with the completely separate Proposition 36 approved by California voters in 2024.
What Did the New Proposition 36 Change?
California voters approved another measure numbered Proposition 36 in November 2024.
The newer Proposition 36 changed California law concerning certain drug and theft crimes and created a new treatment-mandated felony process for some repeat drug-possession cases.
Under Health and Safety Code section 11395, a person who possesses certain qualifying “hard drugs” and has two or more specified prior drug convictions can potentially face a treatment-mandated felony charge.
Qualifying drugs can include substances such as:
- Fentanyl
- Heroin
- Cocaine
- Cocaine base
- Methamphetamine
- PCP
- Certain other substances specified by the statute
The treatment-mandated felony process provides an opportunity for qualifying defendants to complete treatment and potentially obtain dismissal of the charge.
However, it is not the same thing as traditional drug court or Penal Code section 1000 pretrial diversion.
Does the Treatment-Mandated Felony Require a Guilty Plea?
Yes.
This is an important distinction from ordinary Penal Code section 1000 pretrial diversion.
Under the treatment-mandated felony procedure, the defendant generally pleads guilty or no contest and admits the qualifying prior convictions before judgment is deferred while the defendant participates in treatment.
If the defendant successfully completes treatment and satisfies the statutory requirements, the charge can be dismissed.
If treatment is not successfully completed, judgment can be entered and the defendant may be sentenced.
Drug Court vs. Drug Diversion vs. Treatment-Mandated Felony
California now has several treatment-oriented mechanisms that can sound similar but operate differently.
Penal Code 1000 drug diversion generally involves qualifying personal-use drug offenses and occurs before trial without requiring an initial guilty plea.
Drug court is a collaborative treatment court program involving close supervision and treatment. Many adult drug courts operate after a plea, although program structures vary.
The original 2000 Proposition 36 established treatment-oriented probation for qualifying nonviolent drug-possession offenses.
The 2024 Proposition 36 treatment-mandated felony applies to certain repeat defendants accused of possessing qualifying hard drugs and involves a plea followed by treatment and deferred judgment.
Determining which option may be available requires looking at the actual charges, criminal history, local court programs, and circumstances of the case.
What Happens If You Successfully Complete Drug Court?
The result of successful drug court completion depends on the particular program and the agreement under which the defendant entered it.
Potential benefits can include:
- Reduction of charges
- Dismissal of charges in qualifying programs
- Reduced sentencing consequences
- Successful completion of probation requirements
- Treatment of an underlying substance-use disorder
Because California drug courts do not all use the same model, a defendant should understand exactly what the promised legal outcome will be before entering the program.
What Happens If You Do Not Complete Drug Court?
The consequences of unsuccessful participation also depend on the program and the agreement made when the defendant entered drug court.
Programs may use graduated responses to noncompliance rather than immediately terminating a participant for every violation.
However, repeated violations, new criminal conduct, refusal to participate in treatment, or other serious failures can ultimately result in termination from the program.
If a participant entered a plea before beginning drug court, termination can expose that person to sentencing based on the underlying case and the terms of the agreement.
This is one reason the consequences of entering drug court should be understood before a plea is entered.
Does Drug Court Mean You Avoid Jail?
Not necessarily.
Drug court can provide an alternative to traditional incarceration in appropriate cases, but participation should not be understood as a guarantee that a person will never spend time in custody.
The terms of the program, underlying criminal charges, violations, prior record, and individual circumstances can affect whether custody is imposed.
The more important question is what legal and treatment benefits the particular drug court program offers compared with the alternatives available in the case.
Can Drug Court Apply to Charges Other Than Drug Possession?
Potentially.
Drug courts focus on substance-use disorders and the relationship between those disorders and criminal behavior.
Some participants may therefore have criminal charges other than simple possession.
Eligibility depends on the particular court program, the nature of the charges, criminal history, treatment needs, and public-safety considerations.
A defendant should not assume that a non-possession offense automatically makes drug court either available or unavailable.
Which Treatment Option Is Best?
There is no single answer.
A defendant might potentially face choices involving:
- Penal Code section 1000 pretrial diversion
- Drug court
- Probation with treatment conditions
- The original Proposition 36 treatment provisions
- A Proposition 36 treatment-mandated felony
- Another county-specific treatment or collaborative court program
Those alternatives can have very different consequences regarding guilty pleas, convictions, sentencing exposure, supervision, treatment requirements, and dismissal.
The best option depends on the facts of the individual case.

California’s treatment alternatives have changed significantly since the original Proposition 36 was approved in 2000.
Someone facing a drug-related criminal charge should understand not only whether treatment is available, but also whether participation requires a guilty plea, what happens if the program is completed, and what consequences can follow if the program is not completed.
