A charge under California Health and Safety Code § 11370.1 is a standalone felony count. It alleges unlawful possession of a substance covered by that section while the person was armed with a loaded, operable firearm available for immediate offensive or defensive use. A gun near drugs does not, by itself, establish every part of this charge.
The statute lists cocaine base, cocaine, heroin, methamphetamine, fentanyl, and specified forms of PCP. Section 11401 can also bring a proved controlled-substance analog within the offense; an allegation about an analog requires its own analysis. Section 11370.1 sets state-prison terms of two, three, or four years. It also excludes a person convicted under this section from Penal Code chapter 2.5 diversion or deferred entry of judgment. The statute separately does not apply to lawful fentanyl possession, including possession under a valid prescription. These rules concern this particular count; they do not describe every drug-and-firearm case.
What must the prosecution prove?
The official 2026 CALCRIM No. 2303 describes the elements and how the firearm and drug conditions fit together. The questions below help identify what the accusation depends on; the evidence and applicable instructions in a particular case need counsel’s review.
| Issue | What to check in the accusation and evidence |
|---|---|
| Covered drug and possession | Is the substance named in § 11370.1, or does the charge allege an analog under § 11401? What evidence connects the accused person to possessing it? CALCRIM 2303 requires proof the person knew the drug was present and knew its controlled nature. |
| Usable amount | CALCRIM 2303 describes a usable amount and excludes useless traces or debris. It does not require enough of the drug to intoxicate someone, and it gives no fixed gram threshold. The test is the instruction’s usable-amount definition, applied to the actual substance and evidence. |
| Firearm condition and timing | Was the firearm loaded and operable, and available for immediate offensive or defensive use while the person possessed the drug? If it was not then immediately available, the firearm-availability element is not met. |
| Knowledge of availability | Did the person know the firearm was available for use? CALCRIM 2303 does not require the prosecution to prove the person knew the firearm was loaded or operable. |
| Lawful fentanyl possession | If the substance was fentanyl, was the possession lawful? Section 11370.1(b) excludes lawful fentanyl possession, including possession with a valid prescription. |
The usable-amount rule comes from CALCRIM 2303. It does not create an automatic result for trace evidence: the actual material, testing, and facts must be assessed under the instruction. The statute’s named-drug list and the instruction’s proof requirements should both be checked; the phrase “drugs and a gun” does not replace either analysis.
Is this the same as a firearm enhancement?
No. Section 11370.1 itself creates a felony count with its own elements and punishment. A Penal Code firearm enhancement is a separate allegation connected to another qualifying offense. If charging papers list both a § 11370.1 count and an enhancement, each must be read on its own terms. Do not assume that a reference to a firearm means the papers allege this particular count.
What records can help clarify the count?
Start with the complaint, information, or indictment and any amendments. Confirm whether they cite § 11370.1, a different drug-possession statute, a Penal Code enhancement, or more than one allegation. Then have counsel compare the allegations with the evidence about:
- The substance’s identity and test results, and whether the prosecution claims it was a usable amount.
- Where the substance was found, who had access or control, and what shows the accused knew it was there and knew what it was.
- Where the firearm was, whether it was loaded and operable, whether it was immediately available while the drug was possessed, and what shows the accused knew it was available.
- Whether the substance was fentanyl and, if so, what records bear on lawful possession or a prescription.
- The exact count and any separate enhancement, along with the term and diversion consequences the statute describes.
