Quick Answer
California drug crimes fall into possession (Health & Safety Code §§ 11350, 11377, 11357), under-the-influence (HS § 11550), possession for sale (HS §§ 11351, 11378), sale/transportation (HS §§ 11352, 11379), and manufacturing (HS § 11379.6). Prop 47 (2014) reclassified most simple-possession offenses as misdemeanors. PC § 1000 drug diversion remains the default disposition for first-time simple possession. The Fourth Amendment is the most powerful weapon in any drug defense.
Key Takeaways
- Simple possession (HS §§ 11350, 11377) is a misdemeanor after Prop 47, maximum 1 year county jail.
- PC § 1000 drug diversion dismisses charges after completion of a drug-education program.
- Possession for sale (HS §§ 11351, 11378) is a felony with significant prison exposure.
- Marijuana possession is largely decriminalized by Prop 64 (Adult Use of Marijuana Act); possession of under 28.5g for adults 21+ is no longer criminal (HS § 11357).
- Fourth Amendment search-and-seizure motions (PC § 1538.5) are the workhorse defense in drug cases.
- Constructive possession requires knowledge, dominion, and control, a passenger’s mere proximity is not enough.
- Lab testing, chain of custody, and quantity disputes are technical defenses that often produce reductions.
- Immigration consequences are severe for any drug conviction other than first-offense simple marijuana possession (8 U.S.C. § 1227(a)(2)(B)).

Possession vs. possession for sale, the critical distinction
The single most important charging-level call in a drug case is whether the offense is simple possession (misdemeanor) or possession for sale (felony). Prosecutors look at:
- Quantity — more than personal use is the most common factor.
- Packaging — multiple small baggies suggest sale, one larger amount suggests personal use.
- Scales, ledgers, pay-owe sheets — indicators of sale.
- Cash — particularly small denominations.
- Communications — texts or messages discussing transactions.
- Expert testimony — narcotics officers offer opinion testimony that quantity is consistent with sale.
Most felony drug cases can be reduced to misdemeanor possession with the right facts and the right pre-filing or preliminary-hearing work.
The Fourth Amendment, the workhorse defense
Most drug evidence comes from searches. If the search was illegal, the evidence is suppressed under Mapp v. Ohio (1961) 367 U.S. 643. A PC § 1538.5 motion to suppress is filed pretrial in superior court. The typical lines of attack:
- Traffic stop without reasonable suspicion — Whren v. United States (1996) 517 U.S. 806, pretextual but objectively valid stops are OK, truly baseless stops are not.
- Stop prolonged beyond its lawful purpose — Rodriguez v. United States (2015) 575 U.S. 348, bars detention beyond what is needed to complete the traffic mission.
- Search incident to arrest exceeded scope — Arizona v. Gant (2009) 556 U.S. 332 limits vehicle searches.
- Probation/parole search outside terms — applies only to the searchable subject and items they control.
- Defective warrant — lack of probable cause, stale information, omission of material facts in the affidavit (Franks v. Delaware (1978) 438 U.S. 154).
- Consent invalid — coerced or beyond scope.
Constructive possession defenses
Where drugs are found in a place accessible to multiple people (shared car, shared apartment), the prosecution must prove the defendant had knowledge of the drug’s presence, knowledge of its nature, and dominion and control. CALCRIM 2304. A passenger in someone else’s car is not in possession without more. A roommate is not in possession of drugs in another roommate’s bedroom without more.
Lab and quantity defenses
The prosecution must prove the substance was actually the controlled substance charged, in a usable quantity. Defense investigation:
- Request the lab report and underlying notes, review the testing method.
- Demand a sample for independent testing (CCP § 1054.1).
- Challenge chain of custody where evidence handling was sloppy.
- Argue “usable quantity” — residue or trace amounts may not be enough (People v. Leal (1966) 64 Cal.2d 504).
Diversion as the default disposition
For simple possession, the strong default disposition is PC § 1000 drug diversion. Eligible defendants enter a deferred-entry plea, complete an education program (typically 6 months), and the case is dismissed. Even in cases where the prosecution initially refuses, a defense motion under PC § 1001.36 (mental health) or § 1001.95 (judicial misdemeanor diversion) may get there.
Marijuana, what Prop 64 changed
Since 2016, adults 21 and older may legally possess up to 28.5 grams of cannabis and up to 8 grams of concentrated cannabis (HS § 11357). Possession over those limits is a misdemeanor (HS § 11357(c)). Cultivation of up to 6 plants for personal use is legal at home (HS § 11358). Sales without a license remain illegal (HS § 11360), though most non-violent first-time offenses are misdemeanors.
Prop 64 also allows resentencing and record clearance for prior marijuana convictions under HS § 11361.8.
Immigration warning
Federal immigration law treats almost any drug conviction as deportable under 8 U.S.C. § 1227(a)(2)(B), with a narrow exception for a single offense of simple possession of 30g or less of marijuana. PC § 1000 deferred-entry pleas were once safe but post-Lujan-Armendariz v. INS (1999) 222 F.3d 728 protection has narrowed, many noncitizens are now better served by avoiding any plea and getting the case dismissed outright. Legal permanent residents and other non-citizens need Padilla v. Kentucky (2010) 559 U.S. 356 analysis before any plea.
What to do right now
- Do NOT consent to additional searches.
- Do NOT make statements to police about ownership, purchase, or use.
- Preserve any evidence of the search, video, photos of the scene, witness names.
- If charged, get the police report and the lab analysis ASAP, both shape strategy.
- If you’re a noncitizen, tell counsel upfront. Plea consequences are different.

Frequently asked questions
What changed for drug possession after Prop 47?
Simple possession (Health and Safety Code §§ 11350, 11357, 11377) was reduced from felony to misdemeanor. Older felony convictions can be retroactively reduced under Prop 47.
Is possession-for-sale still a felony?
Yes. HS § 11351 (possession for sale of controlled substances), § 11378 (meth for sale), and § 11379 (transportation for sale) remain felonies and are not eligible for Prop 47 reduction.
What defenses are common in drug cases?
Unlawful search and seizure (Fourth Amendment, PC § 1538.5 motion), lack of knowledge of the substance, lack of possession (constructive vs. actual), entrapment, and chain-of-custody challenges to the substance itself.
Can drug cases be diverted to treatment instead of prosecution?
Many. PC § 1000 covers eligible simple-possession cases. PC § 1001.36 covers cases with mental health components. Drug Court is available in most LA courthouses.
What if the drugs were found in someone else's car or apartment?
Lack of possession is a real defense. The prosecution must prove the defendant knew of the substance and had dominion and control over it. Mere proximity is not enough.
