Why You Need a Drug Charges Lawyer in California NOW

Drug charges in California always need to be taken seriously. The same action can be interpreted by the state in multiple ways, meaning you're risking felony consequences.

The first reason you need a drug charges lawyer right away is to help you understand the charges. A simple possession case shouldn't be treated the same as a drug trafficking case, and your defense attorney should understand how to defend each.

The second reason to call a drug charges lawyer as soon as you've been accused is to stop yourself from making a mistake. If you say something incorrect in an interrogation, you could see simple possession allegations elevated to possession-for-sale accusations. Your attorney can advise what to share and what not to share with the state.

Finally, your drug charges lawyer will give you access to expertise and relationships you wouldn't otherwise have. Early intervention lets us build a defense before the prosecution has completed its case, and we can even move to dismiss charges if we act early enough.

California Drug Types and Their Penalties:

When you work with a California drug charges lawyer, you want someone who knows how the prosecution treats different drug types. Below, we've listed some of the most common substances that are the center of illegal drug cases in the state.

Drug TypeDescription
Prescription DrugsCharges often revolve around having a technically legal drug without permission, or selling it to someone you aren't supposed to.
EcstacyA synthetic drug closely related to methamphetamine. A stimulant often used at parties.
CocaineA highly addictive stimulant derived from a South American plant. It is taken in a variety of ways.
MethamphetamineSynthetic stimulant originally used to improve focus, but with serious side effects.
OpioidsClass of drugs originally intended for use as pain relievers. These include morphine, oxycodone, and heroin.
HeroinA highly refined type of opioid. Courts and prosecutors often treat heroin charges harshly.
FentanylOne of the most dangerous forms of opioids — roughly 50 times more potent than heroin and 100 times more potent than morphine, according to the DEA.

Penalties vary significantly by substance, quantity, prior record, and whether the charge is possession, possession-for-sale, or sale/transport. As a general framework:

  • Simple possession of most controlled substances is typically charged as a misdemeanor, punishable by up to one year in county jail, though certain substances and circumstances can elevate this.
  • Possession for sale, sale, transport, or manufacturing are typically charged as felonies, with sentencing ranges that depend heavily on the specific substance and quantity involved.
  • Fentanyl carries additional exposure: Proposition 36 (2024) added fentanyl alongside cocaine, heroin, and methamphetamine to a list of drugs that trigger felony enhancement when possessed together with a loaded firearm, and it increased sentencing exposure tied to quantity for several substances.
  • Federal charges carry their own, generally harsher, sentencing structure.

Because the numbers shift based on the specific facts of a case, the exact exposure you're facing should be evaluated by an attorney who can review your charge sheet and criminal history — call us for a free case evaluation and we'll walk you through what you're actually facing.

Marijuana in California

Marijuana Description: Marijuana is a mind-altering substance derived from a plant leaf. While the state used to have laws against its use, in 2016 it passed Proposition 64, legalizing its recreational use.

Because it has been legalized for casual use, marijuana (AKA cannabis) charges in California most often center around when and where it is used. For example, driving with an open package of marijuana is illegal, even if you are sober.

Marijuana Legal Overview:

  • Legal in limited quantities for adults 21 and older
  • In most cases, it is legal to grow up to six marijuana plants
  • Still illegal to use or possess under federal law.

How a California Drug Charges Lawyer Can Help: If you're facing marijuana-related charges, our attorneys can help. For example, we can show the legality of your ownership, demonstrate that you did not exceed state limits, and/or show that it was properly handled at all times.

Different Types of Drug Charges in California

The Law Offices of David S. Chesley defends a wide variety of drug charges in California. We are prepared to fight against accusations including possession, sale, and special enhancements. Read the sections below to learn more about the different categories of charges and how our criminal defense attorneys can help.

Drug Possession/Use Charges

Drug possession charges are some of the most basic in California. They cover a wide range of substances and can apply if the drugs are on your person, in your vehicle, or anywhere you would control access to them.

Your California drug charges lawyer can help by arguing that the drugs were not actually yours, and can advocate for diversionary programs to keep you out of jail.

Relevant statutes: Simple possession of most hard drugs falls under Health and Safety Code 11350, while possession of methamphetamine specifically falls under HS 11377. Both are typically charged as misdemeanors, punishable by up to one year in county jail, for defendants without disqualifying prior convictions.

Drug Production/Transport/Distribution Charges

While drug possession and use charges target the buyer, drug production, transportation, and distribution charges target the seller.

These charges are almost always treated more harshly than possession/use charges. A drug crimes defense lawyer can help you negotiate a plea to a less serious offense.

Relevant statutes: Possession for sale generally falls under HS 11351 (most controlled substances) or HS 11378 (methamphetamine), each a straight felony punishable by two, three, or four years in state prison and fines up to $20,000. Sale or transportation for sale is charged under HS 11352 (most substances) or HS 11379 (methamphetamine), and carries longer exposure — up to nine years if the transportation crosses non-contiguous counties. Unlike simple possession, these charges are generally not eligible for PC 1000 or Prop 36 treatment diversion unless your attorney can negotiate the charge down to simple possession.

Drug Charge Enhancements

California's drug charge enhancement laws cover a variety of situations, but all have one thing in common: They don't exist on their own. To be charged with an enhancement, there also needs to be an underlying base charge.

It's even more important to hire an experienced California drug crimes lawyer to defend you in these cases, so that they can fight both the base charge and the enhancement.

Federal Drug Charges

A federal drug charge could fall into any of the three categories above. What sets these apart is that the federal government is prosecuting you instead of the state government.

These can include anything from production to transportation to running a drug ring, but most often will involve large quantities and/or crossing state lines. The penalties are often much harsher, up to and including life imprisonment and substantial fines.

These are some of the most serious charges you can possibly face. And you need a leading criminal defense lawyer who has the strength to match the United States government's resources. Our office will conduct investigations, research applicable laws, review evidence, and do whatever we can to secure a positive outcome for you.

DUIs and Drug Charges Defense in California

Drug cases often intersect with another type of case in California: DUIs. Drug DUI defense cases cover a wide range of situations, including everything from driving while high on marijuana to prescription drug usage. What's worse, you can be arrested if there is any amount of THC in your system while driving (as opposed to alcohol).

When facing this type of charge, you don't just need a drug charges lawyer. You also need a leading California DUI defense lawyer who will fight your case both in criminal court and at the DMV hearing. But you need to act fast — in most cases, you only have ten days after an arrest to request a hearing.

What to Look For in a Drug Charges Lawyer

When you are considering your options for a drug charges lawyer in California, it can be overwhelming trying to decide which one to represent you. With so much at stake, you don't want to make the wrong choice.

Here are the top factors you want to see in your drug defense attorney:

  • Extensive Experience fighting against these charges
  • Intimate Knowledge of how the state builds its case against you
  • A Track Record of Success when fighting drug charges for clients
  • Availability Anytime because emergencies don't always happen in business hours

We will always be honest with you about the state of your case, and you can get a hold of us 24/7 if you have any questions or concerns.

Strong Defense Strategies Our Attorneys Use in Drug Cases

Your charges might be the same as someone else's, but your case is unique. Everyone in the California criminal courts is there under different circumstances, and you should have a customized defense plan to match.

We'll listen to your story and craft a powerful defense to fit. Here are some of the possible strategies your drug charges lawyer will consider:

  • Illegal Search and Seizure: If the police searched you, your vehicle, or your dwelling without either probable cause or a warrant, that evidence can be thrown out.
  • Lack of Intent: If you did hold or transport illegal drugs, but weren't aware of it, you shouldn't be found guilty because you didn't mean to break the law.
  • Not Your Drugs: This defense can be used if there were, in fact, drugs present, but you had no control or ownership over them.
  • Entrapment: In some cases, if an undercover officer coerced you into buying or using illicit drugs, you cannot be held liable for doing so.
  • Prescription: Some substances are illegal to possess without a valid prescription, but if you have one, that can excuse you from these charges.
  • Plea Negotiations: In some cases, where it's not reasonable for the alleged offender to have the charges dropped entirely, a positive outcome can still be achieved through a plea deal.

California Drug Charge Diversion Options:

California has diversion and treatment options available, which your drug charges lawyer can try to utilize in your case. To qualify, defendants must fit certain criteria. Below are two of the most relevant programs:

PC 1000 Drug Diversion

California PC 1000 pretrial diversion is a pretrial diversion path for specified eligible charges and people under Penal Code §§ 1000–1000.1. The present process begins with a not-guilty plea and court-approved education or treatment conditions, rather than the former guilty-plea Deferred Entry of Judgment procedure. After satisfactory completion, a positive program recommendation and the required motion, the court dismisses the eligible charge within the statutory period. The actual order and Penal Code § 1000.4 control arrest-record effects and exceptions; enrollment alone does not promise dismissal or erase every consequence. For related context, see collateral consequences.

Proposition 36 (2024)

Proposition 36, which took effect in December 2024, changed California's approach to repeat drug offenses. It's important to understand that this is a different, newer law than the Proposition 36 passed in 2000, and it works differently than a traditional diversion program.

A 2024 Health and Safety Code § 11395 treatment background-mandated felony allegation requires a qualifying current possession offense involving a listed drug and at least two prior convictions for the statutes enumerated in § 11395(c). Those priors must be alleged in the accusatory pleading and admitted in open court or found true. Two unspecified “drug convictions” do not establish eligibility or felony exposure. A person electing the treatment path pleads guilty or no contest, admits qualifying priors and has judgment deferred during an individualized court-approved program.

Your drug charges lawyer can help you understand whether you qualify for treatment-mandated felony treatment, advocate for that path where it's available, and fight to keep a conviction off your record.

Immigration Consequences of a Drug Conviction

If you are not a U.S. citizen, a drug conviction can be far more damaging than the criminal penalty alone — and this is an area where our firm's dual criminal defense and immigration practice gives clients a real advantage.

Under federal immigration law, a conviction for almost any controlled substance offense can make a non-citizen deportable, with one narrow exception: a single offense involving possession of 30 grams or less of marijuana for personal use. This applies to lawful permanent residents ("green card" holders) as well as visa holders, and it applies regardless of whether the state court sentence includes any jail time.

A few key distinctions matter a great deal:

  • Simple possession for personal use (other than certain rare substances) is generally a deportable offense, but is not automatically classified as an "aggravated felony" — a distinction that can preserve certain forms of immigration relief.
  • Possession for sale, sale, or trafficking convictions are far more likely to be treated as aggravated felonies, which can trigger mandatory deportation with little to no opportunity for relief or future re-entry.
  • How a charge is pled matters enormously. Under Padilla v. Kentucky, defense counsel has a constitutional duty to advise a client of these immigration consequences before a plea is entered. An attorney who understands both sides can negotiate a resolution — such as a plea to a non-drug offense, or a disposition that avoids specific "aggravated felony" language — that may preserve a client's ability to stay in the country.

Because immigration consequences are triggered by conviction, not just sentence, decisions made early in a criminal case can matter as much as, or more than, the eventual sentence itself. If you are a non-citizen facing any drug charge, tell your attorney immediately — this materially changes how your case should be defended.

Frequently Asked Questions

Will a drug charge show up on a background check even if the case is dismissed?

An arrest or dismissed case can appear in some records. The 2024 § 11395 process is not an automatic substitute for custody or a guaranteed sealed record. A person may elect the statutory treatment path if the charge and priors qualify; after successful completion, a positive program recommendation and the required motion, the court shall dismiss the charge. Section 11395(d)(3) applies the stated Penal Code § 1000.4 arrest-record protections, including exceptions; a separate sealing order is permissive, not automatic. If treatment is refused or fails, the court applies the statute’s hearing and sentencing rules to the actual case.

Do I have to talk to police if I'm caught with drugs?

No. You have the right to remain silent and the right to an attorney. Politely decline to answer questions beyond identifying yourself, and ask for a lawyer immediately — anything you say can be used to elevate a simple possession charge to a possession-for-sale charge.

Can a drug conviction be expunged in California?

Many drug convictions can be expunged under Penal Code 1203.4 once probation is successfully completed, though eligibility depends on the specific charge and your record. An expungement does not erase a conviction for federal immigration purposes, which is why non-citizens need immigration-aware counsel handling both the criminal case and any later cleanup.

What's the difference between PC 1000 and Proposition 36 diversion?

Current PC 1000 is pretrial diversion under Penal Code §§ 1000–1000.1 for specified charges and eligible people, using a not-guilty plea and court-approved program. The 2024 Proposition 36 added § 11395 for specified repeat possession allegations with enumerated priors; its treatment election involves a guilty or no-contest plea and deferred judgment. The 2000 Proposition 36 is a different treatment law. Eligibility, noncompletion consequences and record effects depend on the filed statute and court order.

Is a first-time drug possession charge a felony in California?

Simple possession of most controlled substances for personal use is typically a misdemeanor for first-time offenders. Possession with intent to sell, manufacturing, or trafficking charges are generally felonies regardless of prior record.

Every Drug Charge Our Lawyers Defend Against:

Reading the charge and the two drug-treatment laws

The complaint and citation matter more than a broad label such as “drug crime.” Simple possession under Health and Safety Code § 11350 or § 11377, being under the influence under § 11550, possession for sale under § 11351 or § 11378, and transportation for sale under § 11352 or § 11379 require different proof. If police found an item in a shared car or room, the government still has to prove knowing control of the charged substance; shared access alone neither proves nor defeats possession. If a sale allegation appears, ask what evidence supports intent to sell beyond the amount. If a transportation allegation appears, the current statutes require transportation for sale. Keep the complaint, release conditions, any search inventory and later lab result together so counsel can compare what was first alleged with what was actually filed.

PC 1000 today is pretrial diversion, not a present-day guilty-plea “Deferred Entry of Judgment” procedure. Penal Code § 1000 lists eligible offenses and history/charge conditions. Section 1000.1 says the defendant pleads not guilty, waives specified speedy-hearing and trial rights, and may enter a court-approved education or treatment program. The court dismisses an eligible charge after successful completion, a positive recommendation and the required motion within the statutory timing. Enrollment alone does not dismiss the case. Some court pages still use the older DEJ shorthand; the actual statutory procedure and signed order control. Section 1000.4 defines the qualified arrest-record effect and exceptions, including licensing and law-enforcement contexts. It permits, rather than automatically issues, a sealing order.

The 2024 Proposition 36 is different from the 2000 Proposition 36 treatment measure. The newer measure added Health and Safety Code § 11395, a treatment-mandated felony process for specified possession offenses and substances. Two prior convictions are relevant only if they are among the statutes listed in § 11395(c), are alleged in the charging paper, and are admitted or found true. A person who elects the statutory treatment path pleads guilty or no contest and admits qualifying priors, with judgment deferred while treatment proceeds. After successful completion, a positive recommendation and the specified motion, the court dismisses the charge and applies the arrest protections the law identifies. This is not automatic eligibility for anyone with “two drug priors,” and it should not be confused with current PC 1000. The old and new Proposition 36 paths have different plea and record consequences.

The defense review should match the charge to evidence: source and custody of any substance, laboratory identification, who controlled the location, statements and recordings, alleged sale indicators, search authority, and prior-conviction documents. A person considering treatment should ask about program length, cost, attendance, testing, consequences of noncompletion and whether the actual case qualifies. A noncitizen should obtain criminal and immigration advice before any admission or plea; a California dismissal does not answer every federal question. If professional licensing, employment, or a driving allegation also matters, raise it at the start rather than relying on a generic promise that a drug case will leave “no record.”

Evidence questions to bring to the first case review

Write a private timeline of the stop, search and arrest while details are fresh. Note who could access the vehicle, room, bag or device; where each item was located; what the officer said was observed; and whether a search warrant, claimed consent or other asserted authority appears in the report. Keep a copy of lawful prescription records, relevant messages, treatment documentation and any witness names for counsel. Do not ask others to coordinate stories or delete material. The defense may need to compare body-camera footage, dispatch records, laboratory notes and chain-of-custody records with the filed charge rather than relying on the arrest summary alone.

If the accusation is possession for sale, ask which facts are alleged to show intent to sell and whether the prosecution can actually link those facts to the accused person. Packaging, cash or phone messages can have more than one explanation; they do not replace proof of the statutory elements. If the accusation is transportation for sale, ask what supports the for-sale purpose rather than assuming any travel with a substance meets the charge. A manufacturing or cultivation count needs its own process, equipment, plant-count and control analysis. A firearm, school-zone, jail-entry or fentanyl enhancement must be identified separately in the papers and supported by the additional facts its statute requires. That distinction keeps a serious enhancement from being treated as an automatic consequence of the base drug count.

Finally, keep court and administrative papers separate. A possession citation is not itself a drug-impaired-driving charge. If officers also allege driving under the influence, review the vehicle-law count, test timeline and any DMV notice with counsel as distinct deadlines. If a case is dismissed or completed through diversion, request the final minute order and ask what record relief actually follows. The court’s order, not a generic online success story, determines the next administrative step.
