What Is Heroin Under California Law?

Heroin is classified as a Schedule I controlled substance under California and federal drug scheduling law. Schedule I narcotics are considered highly addictive drugs with no accepted medical use in the United States.

Because heroin is classified as a dangerous narcotic, California law makes it illegal to:

Possess heroin
Use heroin
Sell heroin
Transport heroin
Manufacture heroin
Be under the influence of heroin
Be present where heroin is being used

Depending on the circumstances of your arrest, you may face misdemeanor or felony charges carrying substantial prison exposure and financial penalties.

California Heroin Charges and Penalties

California heroin offenses are prosecuted under several sections of the California Health & Safety Code. The severity of penalties depends on factors such as:

Quantity of heroin involved
Prior criminal history
Intent to sell
Transportation across county lines
Presence of sentence enhancements
Whether minors or weapons were involved

Below are the most common heroin-related criminal charges in California.

Under the Influence of Heroin – Health & Safety Code 11550 HS

Under California Health & Safety Code 11550 HS, it is illegal to be under the influence of heroin or any controlled substance.

Police officers may arrest someone for heroin intoxication if they observe symptoms such as:

Needle marks
Impaired coordination
Slurred speech
Drowsiness
Constricted pupils
Erratic behavior

Penalties for Being Under the Influence of Heroin

A conviction under HS 11550 is generally charged as a misdemeanor and may result in:

Up to 1 year in county jail
Informal probation
Court-ordered rehabilitation
Mandatory drug counseling
Fines up to $1,000

In many cases, first-time offenders may qualify for California drug diversion programs instead of jail time.

Possession of Heroin for Personal Use – Health & Safety Code 11350 HS

California Health & Safety Code 11350 HS prohibits knowingly possessing heroin for personal use.

Even a very small amount of heroin can support a criminal possession charge. Prosecutors do not need to prove large quantities for a conviction.

To convict someone of heroin possession, prosecutors generally must prove:

The defendant possessed heroin
The defendant knew it was present
The defendant knew it was a controlled substance
The amount possessed was usable

Penalties for Simple Heroin Possession

Simple possession is usually charged as a misdemeanor offense punishable by:

Up to 1 year in county jail
Probation
Drug treatment requirements
Fines up to $20,000

However, certain prior convictions — including serious violent felonies or sex offenses — may elevate the offense to a felony punishable by up to 4 years in prison.

Possession of Heroin for Sale – Health & Safety Code 11351 HS

Possession for sale is significantly more serious than personal possession.

Under HS 11351, prosecutors allege that the heroin was intended for distribution or sale rather than personal use.

Evidence commonly used to support intent to sell includes:

Large quantities of heroin
Packaging materials
Digital scales
Cash
Multiple bindles or baggies
Text messages
Surveillance evidence

Importantly, prosecutors can file possession-for-sale charges even when only a small amount of heroin is recovered if other evidence suggests distribution activity.

Penalties for Possession of Heroin for Sale

Possession for sale is always charged as a felony in California.

Potential penalties include:

Up to 4 years in state prison
Felony probation
Fines up to $20,000

If the heroin quantity exceeds one kilogram, California law imposes enhanced penalties that can add:

3 to 25 additional years in prison
Fines up to $8 million

Drug trafficking enhancements dramatically increase sentencing exposure in large-scale heroin cases.

California Health and Safety Code 11355 prohibits offering, arranging, or agreeing to sell, furnish, transport, administer, or give a controlled substance, especially when delivering a counterfeit drug or fake version.

Selling or Transporting Heroin – Health & Safety Code 11352 HS

California Health & Safety Code 11352 HS prohibits:

Selling heroin
Furnishing heroin
Administering heroin
Giving away heroin
Importing heroin
Transporting heroin for sale

Transportation charges often arise after traffic stops, narcotics investigations, undercover operations, or interstate drug investigations.

Penalties for Selling or Transporting Heroin

Selling or transporting heroin is prosecuted as a felony offense.

Potential penalties include:

Up to 5 years in state prison
Up to 9 years if transported across multiple county lines
Fines up to $20,000

Additional sentencing enhancements may apply when:

The heroin quantity exceeds statutory thresholds
The defendant has prior drug convictions
Organized trafficking allegations exist

In major trafficking cases involving one kilogram or more of heroin, defendants may face:

An additional 3–25 years in prison
Fines reaching $8 million

These cases are often aggressively prosecuted by both state and federal authorities.

Related Heroin Offenses in California

Several related criminal charges frequently accompany heroin arrests.

DUI of Heroin – Vehicle Code 23152 VC

Driving under the influence of heroin can result in DUI charges under California Vehicle Code 23152 VC.

A heroin DUI conviction may lead to:

License suspension
DUI school
Probation
Jail time
Increased insurance costs

Drugged driving investigations often involve blood testing and officer observations from field sobriety tests.

Being Present Where Heroin Is Used – Health & Safety Code 11365 HS

California Health & Safety Code 11365 HS declares that it is a misdemeanor to knowingly be present at the scene where certain controlled substances are unlawfully used if you also aid, assist, or encourage that drug activity.

This offense is generally charged as a misdemeanor and may carry:

County jail time
Probation
Fines
Drug counseling requirements

Many people are surprised to learn they can face criminal charges without personally possessing heroin.

California Drug Diversion Programs for Heroin Charges

In California, the most commonly used drug diversion programs are Penal Code 1000 (PC 1000) and Proposition 36 (Prop 36).

California offers several alternatives to incarceration for eligible defendants facing minor drug offenses.

Drug diversion programs focus on treatment and rehabilitation rather than punishment.

Successful completion often results in:

Dismissed charges
Sealed arrest records
Avoidance of jail
Reduced long-term consequences

Penal Code 1000 Deferred Entry of Judgment

Eligible defendants may qualify for deferred entry of judgment under Penal Code 1000 PC.

This typically requires:

Drug education classes
Counseling
Treatment programs
Compliance monitoring

After successful completion, the heroin charges are dismissed.

Proposition 36 Drug Diversion

Proposition 36 allows many nonviolent drug offenders to receive treatment instead of incarceration.

The program is designed to reduce repeat offenses by addressing addiction issues directly.

California Drug Court Programs

Drug courts supervise rehabilitation through structured treatment plans, testing, counseling, and regular court monitoring.

Judges may offer drug court participation as an alternative to traditional sentencing.

Charges Commonly Eligible for Drug Diversion

Eligible offenses often include:

Simple heroin possession
Being under the influence
Certain low-level drug offenses

However, defendants charged with:

Possession for sale
Drug transportation
Trafficking
DUI offenses

typically do not qualify for diversion programs.

Common Legal Defenses to Heroin Charges

An experienced California criminal defense attorney may use several defense strategies to challenge heroin allegations.

The best defense depends on the facts of the case, police conduct, witness credibility, and constitutional issues.

Illegal Search and Seizure

Police must follow constitutional search-and-seizure laws.

If heroin were discovered during an unlawful search, the evidence may be suppressed under the Fourth Amendment.

Without admissible evidence, prosecutors may be forced to dismiss the case.

Lack of Intent to Sell

In many cases, prosecutors overcharge possession-for-sale offenses.

A defense attorney may argue:

The heroin was solely for personal use
There was no sales activity
No distribution evidence exists

Reducing charges from possession for sale to simple possession can significantly reduce penalties and restore eligibility for diversion.

Entrapment

Entrapment occurs when law enforcement improperly pressures or coerces someone into committing a crime they otherwise would not have committed.

This defense frequently arises in undercover narcotics investigations.

Police Misconduct

Drug investigations sometimes involve misconduct such as:

Fabricated evidence
False police reports
Improper handling of evidence
Violations of constitutional rights

Evidence of misconduct can weaken or destroy the prosecution's case.

Chain of Custody Issues

Prosecutors must prove the alleged heroin was properly collected, stored, tested, and preserved.

Breaks in the chain of custody can create doubt regarding:

Drug identity
Sample contamination
Evidence tampering

Faulty Drug Testing

Crime lab testing errors may lead to inaccurate results involving:

Substance identification
Weight calculations
Chemical analysis

Defense attorneys often challenge laboratory procedures and forensic reliability in heroin cases.

California Heroin Defense Attorney

Heroin charges in California can carry life-changing consequences, including felony convictions, incarceration, and permanent criminal records.

However, many cases involve constitutional defenses, evidentiary weaknesses, or opportunities for diversion that can substantially improve the outcome.

A knowledgeable California criminal defense attorney can evaluate the facts of your case, explain your legal options, and develop a strategic defense designed to protect your future.
