Heroin Laws in California

Possession, Sale, and Penalties Explained

California law treats heroin offenses with extreme seriousness. Heroin is classified as a Schedule I controlled substance, meaning it has no accepted medical use and a high potential for abuse and addiction. As a result,

California has enacted multiple laws making it illegal to possess, use, transport, sell, or manufacture heroin.

Even low-level heroin offenses can carry long-term consequences, including jail or prison time, fines, probation, immigration consequences, and a permanent criminal record.

However, not every arrest results in a conviction, and many heroin cases qualify for drug diversion or treatment-based alternatives.

Is Heroin Illegal in California?

Yes. Heroin is illegal under both California law and federal law. It is classified as a Schedule I narcotic, meaning:

  • It has no accepted medical use

  • It cannot be prescribed by a doctor

  • Possession in any amount is unlawful

  • Sale or transportation is aggressively prosecuted

California law criminalizes not only possession and sales, but also being under the influence of heroin or being present while someone uses it.


Common Heroin Crimes in California

Depending on the circumstances of an arrest, prosecutors may file one or more of the following charges.


Under the Influence of Heroin

Health & Safety Code 11550

It is a crime in California to be under the influence of heroin, even if no drugs are found on your person.

A person may be arrested if officers believe they are exhibiting signs of heroin intoxication, such as:

  • Nodding off

  • Slurred speech

  • Constricted pupils

  • Track marks

  • Impaired coordination

Penalties include:

  • Up to 1 year in county jail

  • A fine of up to $1,000

  • Probation and mandatory drug counseling

This offense is a misdemeanor, and many defendants are eligible for drug diversion instead of jail.


Possession of Heroin for Personal Use

Health & Safety Code 11350

Simple possession occurs when a person knowingly possesses heroin for personal use.

The amount does not matter. Even a small bindle or residue can lead to charges.

Penalties typically include:

  • Up to 1 year in county jail

  • Fines up to $20,000

  • Probation and drug treatment

This offense is usually charged as a misdemeanor, but it can be charged as a felony if the defendant has prior convictions for certain serious offenses, such as violent felonies or specified sex crimes.


Possession of Heroin With Intent to Sell

Health & Safety Code 11351

If law enforcement believes heroin was possessed for sale rather than personal use, the charge becomes far more serious.

Prosecutors do not need to prove an actual sale occurred. They often rely on circumstantial evidence such as:

  • Packaging materials

  • Scales

  • Large amounts of cash

  • Text messages or phone records

  • Lack of personal-use paraphernalia

Penalties include:

  • 2, 3, or 4 years in state prison

  • Fines up to $20,000

If the quantity exceeds 1 kilogram, sentencing enhancements apply:

  • An additional 3 to 25 years in prison

  • Fines up to $8 million

This offense is always charged as a felony.


Selling or Transporting Heroin

Health & Safety Code 11352

Selling, furnishing, transporting, or offering to sell heroin is one of the most aggressively prosecuted drug offenses in California.

Penalties include:

  • Up to 5 years in prison

  • Up to 9 years if transported across county lines

  • Fines up to $20,000

If the amount exceeds 14.25 grams, or if there are prior convictions:

  • Fines increase up to $50,000

If the amount exceeds 1 kilogram:

  • An additional 3 to 25 years in prison

  • Fines up to $8 million


Related Heroin-Related Crimes

Other charges commonly filed in heroin cases include:

  • DUI involving heroin – driving while impaired by heroin is prosecuted as a DUI

  • Being present during heroin use – it is a misdemeanor to be in the same room where heroin is being used

  • Possession of heroin while armed – penalties increase significantly if a firearm is involved


Drug Diversion Programs for Heroin Offenses

California offers several treatment-based alternatives for eligible defendants charged with minor heroin offenses.

Deferred Entry of Judgment (Penal Code 1000)

Eligible defendants may complete a drug treatment program instead of receiving a conviction. Upon successful completion:

  • Charges are dismissed

  • Records may be sealed

Proposition 36

Non-violent drug offenders may receive court-ordered drug treatment instead of jail.

Drug Court

Supervised rehabilitation programs with regular court monitoring.

Not eligible for diversion:

  • Possession for sale

  • Transportation or sales

  • DUI involving heroin


Common Defenses to Heroin Charges

Effective defenses depend on the facts of each case, but may include:

  • An illegal search and seizure in violation of the Fourth Amendment

  • Lack of knowledge that heroin was present

  • No intent to sell, resulting in reduced charges

  • Police misconduct, including fabrication or coercion

  • Entrapment by law enforcement

  • Chain of custody errors or faulty drug testing

  • Improper sentence enhancements

Early legal intervention is often the difference between jail and dismissal.


Why Early Legal Representation Matters

Heroin cases are often overcharged and based on officer assumptions rather than solid evidence. Prosecutors may file severe charges even when treatment-based options are more appropriate.
