Updated

Under the Influence of Narcotics: CA Health & Safety Code 11550

California Health and Safety Code 11550 HS makes it a crime for a person to be under the influence of a controlled substance or a narcotic drug not lawfully prescribed. The offense is a misdemeanor punishable by up to one year in county jail.

Some examples of controlled substances covered by this statute include:

  • cocaine,
  • heroin, and
  • oxycodone.

The language of the code section reads that:

11550. (a)  A person shall not use, or be under the influence of any controlled substance that is (1) specified in subdivision (b), (c), or (e), or paragraph (1) of subdivision (f) of Section 11054, specified in paragraph (14), (15), (21), (22), or (23) of subdivision (d) of Section 11054, specified in subdivision (b) or (c) of Section 11055, or specified in paragraph (1) or (2) of subdivision (d) or in paragraph (3) of subdivision (e) of Section 11055, or (2) a narcotic drug classified in Schedule III, IV, or V, except when administered by or under the direction of a person licensed by the state to dispense, prescribe, or administer controlled substances. It shall be the burden of the defense to show that it comes within the exception. A person convicted of violating this subdivision is guilty of a misdemeanor and shall be sentenced to serve a term of not more than one year in a county jail. The court may also place a person convicted under this subdivision on probation for a period not to exceed five years.

(b)  (1) A person who is convicted of violating subdivision (a) when the offense occurred within seven years of that person being convicted of two or more separate violations of that subdivision, and refuses to complete a licensed drug rehabilitation program offered by the court pursuant to subdivision (c), shall be punished by imprisonment in a county jail for not less than 180 days nor more than one year. In no event does the court have the power to absolve a person convicted of a violation of subdivision (a) who is punishable under this subdivision from the obligation of spending at least 180 days in confinement in a county jail unless there are no licensed drug rehabilitation programs reasonably available.

Examples

  • Going to a concert while under the influence of cocaine
  • Taking several oxycodone tablets and becoming weak, tired, and dizzy
  • Hallucinating after snorting PCP

Defenses

A defendant may assert a legal defense to fight an “under the influence” charge. Some common defenses are that:

Penalties

A violation of this statute is a misdemeanor. This contrasts with a felony or an infraction.

The crime is punishable by imprisonment in county jail for up to one year.

A judge may grant misdemeanor (or summary probation) instead of jail time.

Health and Safety Code 11550 HS makes it a drug crime for a person to be under the influence of a controlled substance or narcotic drug.

1. What does it mean to be under the influence of a controlled substance?

Health and Safety Code 11550 HS is the California statute that makes it a crime for a person to be under the influence of a controlled substance or narcotic drug.1

A prosecutor must prove the following to convict a defendant of this crime:

  1. the defendant willfully used a controlled substance or narcotic drug, and/or
  2. the accused was willfully under the influence of this substance or drug.2

The specific controlled substances and narcotic drugs that fall under this statute are listed in:

  • Health and Safety Code sections 11054-11058 HS, and
  • Health and Safety Code 11019 HS.3

Some of the most common substances and narcotics subject to this law are:

Marijuana is specifically excluded from this code section. Offenses involving marijuana use and possession are regulated separately under California’s marijuana laws.

Questions arise under this statute on the meaning of:

  • willfully,
  • use, and
  • under the influence.

1.1. Willfully

Someone commits an act willfully, under this statute, when he or she does it:

  • willingly, or
  • on purpose.4

Example: John is not guilty under this law if someone “drugged” him or tricked him into ingesting a controlled substance.

1.2. Use

For purposes of this law, the “use” of a drug must be current. This means it must have come “immediately prior to arrest.”5 What “immediately prior to arrest” means is determined on a case-by-case basis.

One court has stated that drug use within five days of an arrest may be enough to support a conviction.6

Other courts have stated that there cannot be current use if an accused started going into withdrawal prior to arrest.7 Withdrawal symptoms, therefore, indicate past drug use which is grounds for an acquittal of this criminal charge.

1.3. Under the influence

Someone is “under the influence of a controlled substance” if the substance has affected the person’s:

  • nervous system,
  • brain or mental condition, or
  • muscles or physical condition.8

This standard is lower than how “under the influence” is treated in a DUI of drugs or a public intoxication case.

HS 11550 only requires that a person is under the influence in any detectable manner.9 Impairment or other misconduct is not necessary to prove this drug charge.

When law enforcement detains someone suspected of being under the influence, they will often call a drug recognition expert (DRE) to the scene. The DRE uses a 12-step process to evaluate whether the subject is, in fact, under the influence.

There are legal defenses to this charge.

2. How does the state prove I was under the influence?

A prosecutor can draw upon several types of evidence to help prove that a defendant was guilty of being under the influence of a controlled substance. The three main types include:

  • testimony of the arresting officer(s),
  • chemical test results, and
  • testimony from a Drug Recognition Expert (“DRE”) officer.

2.1. Testimony of the arresting officer

Law enforcement officers are trained to detect certain signs in suspects that suggest drug use/drug intoxication. For example, any of the following may suggest a party is under the influence of drugs:

  • runny nose,
  • tremors or seizures,
  • chemical odor on a suspect’s breath or clothes,
  • loss of physical coordination,
  • extreme lethargy,
  • bloodshot or watery eyes, and
  • pinpoint pupils.

If an arresting officer observed any of these objective symptoms during the arrest, a prosecutor can have the officer testify in court as to what he/she observed.

2.2. Chemical test results

If a person is arrested for a HS 11550 violation, police will ask the party to submit to a chemical test.

Police request a blood test because a breath test cannot detect the presence of drugs in a person’s system.

If a test comes back positive for a particular drug or drugs, the prosecutor can introduce the test results into evidence to suggest a defendant was under the influence.

Chemical tests can detect the presence of several different drugs, including:

  • methamphetamine,
  • opioids, and
  • cocaine.

2.3. Testimony from a Drug Recognition Expert

A DRE is a member of a law enforcement agency that has received specialized training in recognizing the signs and symptoms of drug intoxication.

Once a non-DRE officer stops a person for being under the influence of a controlled substance, that person may call and ask a DRE officer to help in the investigation process. A DRE officer will then conduct a specialized 12 step DRE Drug Impairment Protocol to measure if a suspect is under the influence.

If the protocol indicates the suspect was under the influence, a prosecutor may call the DRE officer to testify in court as to the protocol’s findings.

3. What are the penalties?

A violation of this statute is a misdemeanor.

The crime is punishable by imprisonment in county jail for up to one year.

In some cases, the defendant may qualify for a drug diversion program, which consists of drug counseling and drug rehabilitation.  These programs allow people who have committed non-violent drug offenses to serve their sentences in drug treatment programs in lieu of jail or prison.

Note that the L.A. County D.A.’s office generally does not prosecute HS 11550 cases.11

4. Are there immigration consequences?

A conviction under this law may have negative immigration consequences.

United States immigration law says that certain kinds of criminal convictions can lead to:

A category of “deportable” or “inadmissible” crimes includes certain drug offenses.12

This means, depending on the specific facts of a case, a conviction may lead to detrimental immigration effects.

5. Can a conviction be expunged?

A person convicted of this crime is entitled to an expungement provided that he:

  1. successfully completes probation, or
  2. completes a jail term (whichever is relevant).

If a party violates a probation term, he can still possibly get an offense expunged. This, though, is in the judge’s discretion.

Under Penal Code 1203.4, an expungement releases an individual from virtually “all penalties and disabilities” arising out of the conviction.13

6. Does a conviction affect gun rights?

A conviction does not affect the convicted party’s gun rights.

Some California criminal convictions will result in the defendant losing his right to own a gun.

Some misdemeanors may even carry a 10-year firearm ban.

But an under the influence conviction will not produce these results.

7. Are there crimes related to health and safety code 11550?

There are three crimes related to being under the influence. These are:

  1. driving under the influence of drugs (DUID) – VC 23152f,
  2. driving while addicted to a drug – VC 23152c, and
  3. possession of a controlled substance – HS 11350.

7.1. Driving under the influence of drugs (DUID) – VC 23152f

California Vehicle Code 23152f VC makes driving under the influence of drugs (DUID) a crime.

A driver is DUI of drugs when he can no longer drive like a sober person under similar circumstances due to the use of drugs.

7.2. Driving while addicted to a drug – VC 23152c

Under Vehicle Code 23152c VC, driving while addicted to drugs is considered a form of California DUI.

A driver is considered “addicted to drugs” if he is physically or emotionally dependent upon them.

7.3. Possession of a controlled substance – HS 11350

Health and Safety Code 11350 HS is the California statute that makes it a crime for a person to:

  1. possess a controlled substance, and
  2. do so without a valid prescription.

A person is guilty of this crime for just having access to or control over certain drugs. Unlike HS 11550, there is no requirement that the defendant used a substance or was under the influence of one.

7.4. Drunk in Public – PC 647f

Under Penal Code 647f PC, public intoxication is defined as being intoxicated by alcohol or drugs to the point of being unable to care for oneself. This section only applies when the person is in public, whereas 11550 can apply even when a person is at home or in a private location.

Moreover, a 647f charge requires a much higher level of intoxication. The person must be intoxicated to the point of being a danger to himself or others. HS 11550, on the other hand, only applies to drugs, not to alcohol. And it only requires that the person is under the influence “in any detectable manner.”
