A California drug conviction follows you into employment, housing, and licensing decisions long after the case is closed. The good news is that California has more pathways to clean up a drug conviction than most defendants realize — and depending on your case, the right pathway may not be the standard expungement most people think of. Some old drug convictions have already been redesignated or dismissed automatically without any petition. Some felony drug convictions can be reduced to misdemeanors first, then dismissed, dramatically expanding the relief available. Some cases that completed pretrial diversion years ago still show up as convictions on background checks when they should not — and a specific statutory fix exists for that situation. As a Murrieta criminal defense attorney for over 25 years, Nic Cocis has helped clients across the full range of California drug record relief pathways.
If you have a drug conviction from a case originating in Murrieta, Temecula, Menifee, Lake Elsinore, Wildomar, Winchester, Canyon Lake, or French Valley, any petition for relief is filed in the Riverside County Superior Court branch where the conviction occurred — generally the Southwest Justice Center in Murrieta. This page walks through the major drug-specific record relief pathways, who qualifies for each, what each does and doesn’t accomplish, and how to figure out which one applies to your situation. For the broader framework on California expungement law generally — including the 2026 reform updates and the comprehensive Clean Slate analysis — see the firm’s California expungement laws overview.
What Drug Record Relief Actually Means (and Doesn’t Mean)
The first thing to understand is that “expungement” in California is not what the word suggests. The colloquial term implies erasure or deletion — the record disappears entirely. That is not how California law works. Under Penal Code § 1203.4, the standard expungement statute, the court grants a dismissal: the guilty or no-contest plea is withdrawn, a not-guilty plea is entered, and the case is dismissed. The California Department of Justice still retains the criminal history record. What changes is what most private employers, landlords, and background check services are permitted to see.
For drug convictions specifically, this distinction has several practical implications:
- Most private employment background checks will show the conviction as dismissed rather than as a conviction. This is the most common benefit clients seek.
- Professional licensing treats expunged drug convictions more favorably for new applicants under Business and Professions Code § 480, but existing licensees can still face board discipline for the underlying conduct under § 490.
- Federal contexts treat the dismissal differently. Immigration proceedings often treat a § 1203.4-dismissed conviction as if it still exists. Federal firearm prohibitions are unaffected by California dismissal.
- Future drug cases. A dismissed prior drug conviction can still count for sentencing enhancement purposes in any future drug case.
- Federal drug convictions cannot be expunged under California law at all. Different framework, covered below.
Understanding what each pathway actually accomplishes — not the colloquial “wipe my record clean” expectation — is essential to choosing the right one and to making informed decisions about whether to pursue it.
Pathway 1: PC § 1203.4 — Standard Expungement After Probation
This is the standard expungement most people are familiar with. PC § 1203.4 dismissal is available for most California drug convictions where the defendant:
- Successfully completed probation (full term or terminated early under PC § 1203.3)
- Paid all fines, fees, and restitution ordered by the court
- Completed all probation conditions including any court-ordered drug treatment, classes, community service
- Is not currently charged with another offense
- Is not currently serving any sentence
Most misdemeanor drug convictions and many felony drug convictions qualify. Felony drug convictions that resulted in a state prison sentence are generally not eligible under § 1203.4 directly; those may have separate relief under PC § 1203.41 (felony probation under PC § 1170(h) county jail) or through pardon proceedings.
The petition process in Riverside County involves filing the petition (typically Judicial Council Form CR-180), serving the District Attorney’s Office (15 days’ notice minimum), and either an uncontested order or a hearing if the DA objects. The court has discretion to grant or deny — successful completion of probation creates a strong presumption in favor of granting, but the court can consider subsequent conduct and the nature of the underlying offense. Riverside County practice generally favors granting where the statutory requirements are met and the defendant has stayed out of trouble.
Pathway 2: Prop 47 — Reducing Felony Drug Possession to Misdemeanor
Proposition 47, passed by California voters in November 2014, retroactively reduced many felony drug possession offenses to misdemeanors. This is one of the most important drug record relief pathways for older convictions and is often the necessary first step before any other relief.
Drug offenses affected by Prop 47:
- Health & Safety Code § 11350 — Possession of a controlled substance (cocaine, heroin, etc.) — reduced from wobbler felony to misdemeanor for personal-use possession
- Health & Safety Code § 11377 — Possession of methamphetamine and certain other controlled substances — reduced from wobbler felony to misdemeanor
- Health & Safety Code § 11357 — Possession of concentrated cannabis — reduced (further modified by Prop 64 in 2016)
Under PC § 1170.18, people with pre-Prop-47 felony convictions for these offenses can petition the court to:
- Resentence the case as a misdemeanor (if currently serving a sentence)
- Redesignate the conviction as a misdemeanor (if the sentence is complete)
Why this matters: once a felony drug conviction is reduced to a misdemeanor, the broader expungement framework under PC § 1203.4 becomes available, employment restrictions tied to felony status are removed, certain civil disabilities (jury service, some occupational restrictions) are lifted, and firearm prohibitions tied to felony status may change (though federal firearm prohibitions for any drug-related offense remain). For a defendant with a pre-2014 felony drug possession conviction, the path forward is often: Prop 47 redesignation → then PC § 1203.4 dismissal.
The petition is filed in the court that issued the original conviction. Riverside County Superior Court processes Prop 47 petitions regularly, and the DA’s Office cannot deny the petition where the defendant qualifies and does not pose an unreasonable risk of danger to public safety.
Pathway 3: Prop 64 — Cannabis Record Relief (Largely Automatic)
Proposition 64, passed in November 2016, fundamentally restructured California cannabis law and created a comprehensive record relief pathway for prior cannabis convictions. Under Health & Safety Code § 11361.8, people with pre-Prop-64 cannabis convictions can have their convictions redesignated, dismissed, or sealed depending on the underlying offense.
The critical change in 2018 (AB 1793): California shifted Prop 64 relief from a petition-based system to a largely automatic system. The Department of Justice was directed to identify all eligible cannabis convictions in the state’s records and apply the appropriate relief without requiring individuals to file petitions. The DOJ completed initial processing in 2019-2020 and continues to update records. As a result, many Californians with prior cannabis convictions have already received Prop 64 relief without doing anything and may not realize it.
Cannabis offenses affected by Prop 64:
- HS § 11357 — Possession (reclassified or dismissed depending on amount and circumstances)
- HS § 11358 — Cultivation (reclassified for personal-use quantities; dismissed for amounts now legal)
- HS § 11359 — Possession for sale (reduced or reclassified depending on circumstances and the defendant’s age at the time)
- HS § 11360 — Sale/transport (reduced from felony to misdemeanor in many circumstances)
What this means practically: if you have an older cannabis conviction, the first step is not to file a petition. The first step is to obtain a current copy of your California DOJ criminal history record (via live-scan) and see whether automatic relief has already been applied. If it has, no further action may be needed. If automatic relief has not been applied to a conviction that should have qualified, a petition under HS § 11361.8 can affirmatively obtain it.
Pathway 4: PC § 1000 Drug Diversion — Old Cases and PC § 1203.43
California’s pretrial drug diversion statute (PC § 1000) has gone through several structural changes that left a specific category of older cases in a problematic position. Understanding this matters for anyone who completed drug diversion in California prior to 2018.
Pre-2018 PC § 1000 (Deferred Entry of Judgment). Before AB 208 took effect in 2018, PC § 1000 worked through a “deferred entry of judgment” structure: the defendant pleaded guilty, the court deferred entry of judgment pending completion of the diversion program, and upon successful completion the case was dismissed. The problem: the guilty plea itself was a conviction for many purposes (federal immigration law, federal firearm law, certain background check contexts) even after the case was dismissed.
Post-2018 PC § 1000 (True Pretrial Diversion). AB 208 restructured PC § 1000 as true pretrial diversion: charges are deferred without any plea, the defendant completes the program, and the charges are dismissed without a plea ever being entered. No conviction at any point.
The fix for old cases: PC § 1203.43. Recognizing that pre-2018 PC § 1000 completions left defendants with a record disposition that didn’t match the legislature’s intent, the legislature enacted PC § 1203.43 — which specifically allows defendants who completed pre-2018 PC § 1000 diversion to petition for an order dismissing the underlying plea and setting aside the conviction-equivalent disposition. This is a narrow but important pathway for clients who:
- Completed PC § 1000 drug diversion before 2018
- Currently have a disposition on their record that’s treated as a conviction in some contexts (often immigration)
- Need the conviction-equivalent fully cleared
Identifying whether PC § 1203.43 applies to your case requires reviewing the underlying disposition carefully. Clients often don’t realize they have this option until counsel pulls the original case file.
Pathway 5: Clean Slate (SB 731) — Automatic Relief
The California Clean Slate Act and related provisions (SB 731, AB 1076, SB 1260) substantially expanded automatic record relief beginning in 2023. The framework generally provides:
- Most felony arrests without conviction are automatically sealed three years after the arrest
- Most state felony convictions are automatically sealed four years after the case ends (for offenses not on the exclusion list)
- Most misdemeanor convictions receive automatic relief upon successful completion of probation
- DOJ reviews records monthly and applies automatic relief to qualifying records
For drug convictions specifically, automatic Clean Slate relief is available for most non-sale drug convictions — but the eligibility rules have exclusions (serious or violent felonies, sex offenses requiring registration, certain other categories). The practical implication for most drug-conviction clients: you may already have automatic relief and a petition may not be necessary. The first step is again to obtain a current criminal history record and verify what has already been applied.
Federal Drug Convictions — Different Framework Entirely
Federal drug convictions cannot be expunged under California law. Federal convictions are governed by federal law, and federal expungement is extremely limited — generally available only for first-time simple possession offenses under 18 U.S.C. § 3607(c) and only for defendants who were under 21 at the time of the offense.
For most federal drug convictions, the realistic post-conviction relief options are:
- Federal pardon — Discretionary, application through the Office of the Pardon Attorney, rarely granted
- Certificate of Rehabilitation under federal law — Even more limited than state COR
- Civil rights restoration — Specific to certain consequences rather than the conviction itself
- State expungement of related state charges — If the federal case had a parallel state component, state relief may still apply to the state portion
If you have a federal drug conviction (cases prosecuted in the United States District Court rather than in California Superior Court), the analysis is different and the available pathways are much narrower. See the firm’s federal crimes practice area for additional context.
How to Figure Out Which Pathway Applies to You
Given the multiple pathways and the automatic relief that may already have been applied, the right starting point is rarely “file a petition.” It’s:
Step 1: Obtain a current copy of your California DOJ criminal history record. This is done through the live-scan process (CA DOJ Form BCIA 8016RR), costs about $25 plus the live-scan vendor fee, and produces an official record of what currently appears on your criminal history. Without this record, no one can tell you reliably what relief you already have versus what you still need.
Step 2: Identify what each conviction or arrest actually shows. Some convictions may already be redesignated under Prop 64 or Prop 47. Some may have automatic Clean Slate sealing applied. Some may still appear as original convictions and need affirmative petitions. The DOJ record will show the current state.
Step 3: Identify which pathway applies to each remaining conviction. A felony drug possession conviction may need Prop 47 redesignation first, then PC § 1203.4 dismissal. An old PC § 1000 disposition may need PC § 1203.43 relief. A cannabis conviction may already have Prop 64 relief or may need an affirmative petition. The pathway selection determines what gets filed and how.
Step 4: File the appropriate petitions. Each pathway has its own petition forms, procedural requirements, and DA notice rules. The petitions can often be filed concurrently — Prop 47 redesignation and PC § 1203.4 dismissal in the same matter, for example. Whether attorney assistance is necessary depends on the complexity of the case file and the number of convictions involved.
Step 5: Verify the relief was applied. After the order is granted, the court forwards the order to the DOJ. The DOJ updates the criminal history record. A follow-up live-scan record verifies that the relief was actually applied as ordered. This step is often skipped but is the only way to confirm the relief actually shows up where it matters.

Should You Hire an Attorney or DIY?
This is the practical question every client asks. The honest answer:
- For straightforward single-conviction PC § 1203.4 petitions where you completed probation cleanly years ago, doing it yourself is reasonable. The forms are available, the filing fee is modest, and the process is administratively simple.
- For Prop 47 / Prop 64 redesignation matters, particularly where automatic relief may already have been applied to some convictions and others still need petitions, an attorney review is usually worth the investment. Knowing what’s already done versus what still needs filing prevents wasted effort and missed relief.
- For PC § 1203.43 (old PC § 1000 cases), attorney involvement is generally important because the underlying disposition analysis is technical.
- For multi-conviction cases, mixed misdemeanor/felony situations, or cases where reduction is the first step toward broader relief, attorney coordination of the strategic sequence (which petition first, what the second petition depends on) makes a meaningful difference in outcome.
- For federal convictions, the pathways are so narrow that attorney evaluation is essentially required to determine whether any relief is realistically available.
Initial case review for record relief is generally not expensive, and most clients benefit from at least knowing what their current DOJ record actually shows and which pathways apply before committing to any particular approach.
If you have a drug conviction from a Riverside County case — Murrieta, Temecula, Menifee, Lake Elsinore, Wildomar, Winchester, Canyon Lake, French Valley, or elsewhere in Southwest Riverside County — and you’re considering whether expungement, redesignation, or another form of record relief may be available, call (951) 400-4357 to schedule a free, confidential consultation.
