Charged with Bringing Drugs into a Jail or Prison in California?
Bringing or Possessing a Controlled Substance at a Penal Institution: Identify the Exact Count, Knowledge and Authorization.
California criminal defense attorney David Chesley has successfully defended charges of bringing or possessing controlled substances in a custodial facility — including PC § 4573 (bringing controlled substances into jail or prison), PC § 4573.5 and PC § 4573.8 (alcohol and other substances), and PC § 4573.6 (possession inside) — through knowledge and intent challenges, suppression motions, charge reductions, and diversion pathways in criminal courts across every county in California. These cases are prosecuted aggressively, but many turn on whether the defendant knew the substance was present and intended to bring it in. Both elements are contestable. Build your defense now.
IMMEDIATE STEPS IF CHARGED UNDER PC § 4573 OR RELATED STATUTES:
- Do not make statements to law enforcement, correctional officers, or prosecutors without counsel — statements about knowledge, ownership, or how the substance got there are the prosecution's strongest evidence for the knowledge and intent elements that are most often successfully challenged
- A plea is not inevitable. First identify whether the charge alleges bringing or sending an item under section 4573, or possession inside under section 4573.6; the proof and authorization defenses differ. Review the item, facility, witness accounts and court papers before predicting an outcome.
- Preserve documentation — circumstances of discovery, prescription records, evidence the substance belonged to someone else, notes about what officers said, and any details about facility surveillance
- Contact experienced counsel immediately — facility video is often overwritten quickly; knowledge and intent defenses must be developed from the specific facts before the prosecution's narrative solidifies

THE STAKES ARE REAL
Penal Code section 4573 addresses knowingly bringing or sending a controlled substance or covered paraphernalia into a penal institution or onto its grounds without authorization. Section 4573.6 separately addresses possession there, and other cited sections have their own items and penalties. A court must apply the charged statute and any available sentencing rule; neither a felony conviction nor imprisonment follows from arrest alone. Read the exact complaint and laboratory description before assessing exposure.
A conviction means:
- A conviction may affect a criminal record and employment, but record relief and occupational screening depend on the actual disposition and law.
- Licensing duties and discipline depend on the board, offense, disposition and individual circumstances.
- A controlled-substance conviction can create serious immigration consequences. The exact count, controlled substance, conviction record and any trafficking allegation require case-specific review; a prison-location allegation alone does not determine every federal classification.
- Housing and employment barriers
Many cases involve visitors, family members, or professionals who did not knowingly or intentionally bring contraband. The gap between "substance was found" and "you knowingly brought it in" is where strong defenses exist.
Quick Charge Comparison:
| Charge | Statute | Classification | Key Elements | Typical Sentence |
|---|---|---|---|---|
| Bringing controlled substances | PC § 4573 | Straight Felony | Knowing introduction into facility | Two, three or four years listed in the 2026 court schedule; custody under the applicable Penal Code section 1170(h) sentencing route requires case-specific review |
| Bringing alcohol/other substances | PC § 4573.5 | Wobbler | Bringing non-controlled prohibited items | Misdemeanor or felony |
| Possession inside (controlled) | PC § 4573.6 | Straight Felony | Knowing possession inside | Two, three or four years listed in the 2026 court schedule; custody under the applicable Penal Code section 1170(h) sentencing route requires case-specific review |
| Possession inside (alcohol/other) | PC § 4573.8 | Felony in the current San Diego court schedule | Covered non-4573.6 item and charged location require separate proof | 16 months, 2 or 3 years shown in that court schedule; review actual statute and case |

WHAT THE PROSECUTION MUST PROVE — AND HOW TO CHALLENGE IT
Read the charged section before applying its elements. CALCRIM 2749 for section 4573 asks whether the person knowingly brought, sent or assisted in bringing or sending the covered item into a penal institution or its grounds, knew its controlled character or paraphernalia use, and whether the charged substance and usable amount were proved when applicable. CALCRIM 2748 for section 4573.6 instead asks whether the person possessed the item there, knew of its presence and nature, and, for a substance charge, whether the charged substance and usable amount were proved. The instructions also describe lawful-authorization and, for possession when supported, prescription questions.
Each element is independently challengeable — and defeating any one defeats the charge entirely.
Key Defenses at a Glance:
- Lack of knowledge: You didn't know the substance was in your bag, clothing, or belongings — common when items were given or placed by others
- Prescription medication: A controlled substance prescription can be relevant to possession under CALCRIM 2748, but section 4573 bringing or sending requires review of lawful institutional authorization. Preserve the original label, pharmacy record and staff instructions.
- Suppression: Unconstitutional search of vehicle, person, or belongings before or at facility entry
- Alternate count: If section 4573 cannot be proved, ask whether a distinct lesser or different charge is actually supported through plea negotiation or trial. Section 4573.5 can have a misdemeanor path, but section 4573.8 is not a generic wobbler under the current court schedule.
- Diversion: PC § 1001.95, mental health diversion (PC § 1001.36), or military diversion (PC § 1001.80) where available

INDIVIDUAL DEFENSE EXPLANATIONS — HOW EACH DEFENSE WORKS
Defense One: Lack of Knowledge — The Most Important and Most Frequently Successful Defense
Section 4573 is not established merely by finding an item in a bag. Current CALCRIM 2749 asks whether the person knowingly brought, sent or assisted in bringing or sending the controlled substance or paraphernalia into a covered institution or its grounds, knew the item’s controlled character or intended paraphernalia use, and whether the charged substance and usable amount were proved when required. It does not universally require knowing the exact drug name; a lawful authorization defense may apply when supported.
The unknowing carrier question: If another person supplied a bag, package or jacket, compare messages, handling, access, packaging and surveillance with what the accused knew about the item and its destination. An unknown item can create a real knowledge dispute; the account alone does not prove what happened and is not necessarily the most common case pattern. Preserve the original item and chain of custody for a concrete review.
The borrowed or shared belongings scenario: The substance was found in a bag, item of clothing, jacket, purse, or other belonging that the defendant had borrowed from another person or that was regularly used by multiple people, and the defendant did not know the substance was present in that item. Where the specific item in which the substance was found was not exclusively the defendant's and was regularly used or accessed by others, the knowledge element is challenged through evidence of the item's shared use and the defendant's specific lack of awareness of the substance's presence.
Prescription and authorization: A valid prescription may matter to a section 4573.6 possession count under CALCRIM 2748, while section 4573 bringing or sending turns on its own authorization and knowledge elements under CALCRIM 2749. Review the prescription, bottle, facility policy, staff directions and whether a person in charge authorized entry. A prescription does not by itself authorize bringing medicine into a facility. See the related drug defense topics.
Defense Two: Suppression — Constitutional Challenges to the Search
While correctional facility entrance searches operate under different Fourth Amendment standards than general law enforcement searches — persons entering custodial facilities have a reduced expectation of privacy at the entry point — specific search circumstances in PC § 4573 cases are still subject to constitutional challenge.
Vehicle search near the facility: A parking lot is not an automatic exception to the Fourth Amendment or an automatic ban on searching. Ask whether the car was stopped or parked, who owned it, the applicable warrant or automobile exception, consent, facility notice and actual search scope. A suppression motion concerns identified evidence and the court’s ruling; a successful challenge may affect the prison-entry count, but dismissal depends on what proof remains.
Earlier stop or detention: Obtain body-camera video, dispatch log, stop basis and timestamps. An unlawful detention may affect later evidence, but attenuation, independent source and the facts of any intervening conduct matter. The court must identify which evidence, if any, is excluded; the prior stop does not itself erase every later count.
Search scope: Compare the warrant, consent, facility search policy and actual containers opened. Evidence from an unauthorized area may be challenged, but whether exclusion follows depends on the legal basis, standing and the court’s findings. Preserve consent language, signs, notices and the inventory rather than assuming a particular container was off limits.
Facility video may show entry, handoffs, screening, discovery or who handled a package, if cameras captured those events and the footage still exists. Ask promptly about retention, camera location, access logs and whether recording continued through the relevant time. Video can corroborate or contradict an account, but it cannot be presumed available, comprehensive or decisive. Preserve visitor records, search reports and witness names alongside any video request.
Defense Three: Prescription Medication and Authorization Defense
For section 4573.6 possession, CALCRIM 2748 recognizes a valid-prescription defense when supported by evidence; it also describes authorization under facility rules or by the person in charge. For section 4573 bringing or sending, CALCRIM 2749 addresses lawful authorization to bring the item. A prescription record and compliance with actual facility instructions are relevant, but ignorance of a posted rule alone does not automatically defeat a charge.
Defense Four: Check Whether a Different Supported Charge Has a Misdemeanor Path
Different items require different statutory analysis. If testing shows the material is not a scheduled controlled substance or covered analog, the prosecutor must identify some other supported offense rather than automatically reducing section 4573 to section 4573.5. A proposed misdemeanor, license effect or immigration effect depends on the exact replacement count and disposition. Ask for the charging document, item description, schedule and full laboratory method before negotiating.
Defense Five: Diversion
Current Penal Code section 1000 is a pretrial-diversion framework for specified eligible offenses, not the former guilty-plea deferred-entry system. Section 4573 is not listed merely because an item was a drug. A different filed or negotiated misdemeanor, mental-health diversion, military diversion or a local treatment option requires separate statutory, court and individual eligibility review; no drug-court program, mental-health diversion or military option follows automatically from this count.
Defense Six: Identity and Constructive Possession Challenge
In cases where the substance was found in a location accessible to multiple people — a vehicle with multiple occupants, a shared bag, a common area — the prosecution's attribution of possession to this specific defendant is challenged. The constructive possession framework — requiring proof that this defendant had specific dominion and control over the substance — is applied where the evidence is consistent with the substance belonging to another person with equal or greater access.
Defense Seven: Knowledge of Nature Challenge
Knowledge of the controlled character of the material matters, but current CALCRIM 2749 does not make the exact chemical name a universal element. A belief that a pill was an ordinary noncontrolled supplement may raise a different issue from knowing it was a controlled medication. Compare labels, prescriptions, statements and test results with the actual charged substance; the jury must also decide the institution and bringing or sending elements.
Defense Eight: Laboratory Analysis Challenge
The prosecution must prove the charged substance and usable amount when required, but a formal laboratory report is evidence rather than a universal standalone element of CALCRIM 2749. Field tests, confirmatory methods, sample handling and the link between the tested item and the accused may matter. For possession under CALCRIM 2748, control of the item and awareness of its presence are separate questions; mere use does not automatically prove possession.
PC § 4573 CHARGES AND IMMIGRATION — CRITICAL FOR NON-U.S. CITIZENS
A PC § 4573 felony conviction carries serious immigration consequences — and the immigration analysis must be conducted from the very first consultation before any plea is entered.
Federal Immigration Consequences
The immigration classification depends on the exact conviction, item and federal controlled-substance definition:
- A conviction relating to a federally controlled substance can implicate 8 U.S.C. § 1227(a)(2)(B)(i), subject to the precise count, substance, conviction record and person. A covered item or state label alone does not answer federal removability.
- If a conviction is classified as illicit trafficking under 8 U.S.C. § 1101(a)(43)(B), serious aggravated-felony consequences may follow. A prosecutor’s theory of internal distribution is not the same as a proved federal classification; the precise statute, substance and conviction record must be reviewed with immigration counsel. See possession for sale, trafficking and immigration consequences for distinct subjects.
A section 4573 conviction involving a federally controlled substance can create serious immigration issues, but the effect depends on the statute, substance, record, status and any relief. A distribution allegation does not by itself convert every conviction into a trafficking aggravated felony. Compare an actual proposed plea with 8 U.S.C. §§ 1101(a)(43)(B) and 1227(a)(2)(B)(i), and obtain individualized advice before assuming removal, naturalization or reentry consequences.
What Non-U.S. Citizens Must Do Before Any Plea:
- The immigration consequences of the specific PC § 4573 charge — including whether the specific conduct alleged and any plea entered would constitute a controlled substance offense under 8 U.S.C. § 1227(a)(2)(B)(i), an aggravated felony under 8 U.S.C. § 1101(a)(43)(B), or both — must be analyzed before any plea is entered; the specific theory of the prosecution and what the plea admits determines which immigration consequence is triggered
- A search motion may remove specified evidence; only the actual court and prosecutor disposition determines whether a criminal count is dismissed. Dismissal may avoid conviction-based immigration grounds but does not guarantee that an arrest, admission or other record has no effect.
- A proposed different count may change criminal exposure, but a misdemeanor label alone does not remove federal controlled-substance or trafficking consequences. Compare exact elements, substance and conviction record before treating any reduction as immigration protection.
- No plea to any PC § 4573 or related felony charge should be entered without a full understanding of the federal immigration consequences and a clear assessment of whether the knowledge defense, suppression, or charge reduction is achievable on the specific facts
Immigration analysis for non-U.S. citizens is conducted from the very first consultation in every PC § 4573 case.

YOU HAVE RIGHTS. USE THEM.
The prosecution must prove the charged knowledge and conduct elements beyond a reasonable doubt. For bringing under section 4573, CALCRIM 2749 asks about knowing entry or sending and controlled character; for possession under section 4573.6, CALCRIM 2748 asks about control and knowledge. A visitor record, bag handoff, authorization and item testing may each answer a different element. The defense should not assume an additional specific-intent element that the charged instruction does not contain.
- Knowledge element defeated — defendant demonstrated no knowledge substance was in bag given by another person; prosecution unable to establish knowledge beyond reasonable doubt; charge dismissed
- Suppression granted — vehicle search in parking lot before facility entry lacked probable cause; substance suppressed; PC § 4573 charge dismissed
- Firm-reported prescription result: a prescription and facility authorization facts reportedly affected the disposition. A lawful prescription is relevant under CALCRIM 2748 for possession; bringing under CALCRIM 2749 requires its own authorization analysis.
- Unknowing carrier acquitted at trial — defendant transported package without knowledge of contents; not guilty verdict returned
- Firm-reported reduction: the material reportedly did not support the original section 4573 count and a different misdemeanor was negotiated. The legal elements of section 4573.5 are separate; the exact item, substitute statute and docket require verification.
- PC § 1001.95 diversion granted — qualifying misdemeanor charge; diversion motion filed and granted; program completed; charge dismissed; no conviction recorded
- Mental health diversion granted — defendant's mental health condition contributed to conduct; PC § 1001.36 diversion pursued; charge dismissed; treatment provided
- Firm-reported dismissal: a knowledge challenge and search motion reportedly ended the criminal case without a plea. Immigration effects require review of the actual record, admissions, substance and person; no conviction does not necessarily mean no immigration consequence.
WHY CLIENTS CHOOSE DAVID CHESLEY
Direct, personal attention — statewide, 24/7
David Chesley personally handles PC § 4573 defense in criminal courts across all of California — Los Angeles, San Diego, Orange County, San Francisco, Sacramento, Fresno, San Jose, Riverside, San Bernardino, Ventura, and every other jurisdiction statewide. Available 24 hours a day, 7 days a week — because PC § 4573 cases move quickly, facility surveillance is overwritten rapidly, and the knowledge defense must be developed from the specific facts before the prosecution's narrative solidifies.
Straight talk: Unawareness of an item, facility authorization, an applicable prescription defense for possession, or an unconstitutional search may each affect a different issue. None automatically dismisses every count. Start with the precise section, item and institution, then compare the records against CALCRIM 2748 or 2749, any other charge and the court’s actual ruling.
Multi-front strategy from day one
Knowledge challenge, intent challenge, suppression, prescription defense, charge reduction, diversion, and immigration analysis are all assessed and pursued simultaneously. The most important defense depends on the specific facts — and all available defenses are identified from the first consultation before any single pathway is pursued to the exclusion of others.
Flexible payment plans
The Law Offices of David Chesley offer flexible payment plans because cost should never be the reason someone charged with PC § 4573 goes without experienced legal representation.
Representative Results:
- PC § 4573 charge dismissed — defendant demonstrated through specific evidence that the controlled substance was placed in their bag by another person without their knowledge; prosecution unable to establish knowledge element beyond reasonable doubt; charge dismissed before trial
- Suppression granted — defendant's vehicle searched in facility parking lot before reaching the entrance; search found to lack probable cause; controlled substance suppressed as fruit of unlawful search; PC § 4573 charge dismissed
- Firm-reported prescription result: a visitor’s opioid medication, prescription and institutional authorization reportedly affected the charge. Possession and bringing have distinct instruction defenses; lack of “criminal intent” alone is not a universal answer.
- Unknowing carrier acquitted at trial — defendant transported package from incarcerated individual's associate without knowledge of contents; specific evidence of defendant's genuine lack of awareness of substance presented to jury; not guilty verdict returned
- Firm-reported alternate-count result: the original controlled-substance identification reportedly was not proved and a different misdemeanor was negotiated. Section 4573.5 has its own elements; no generic rule converts every noncontrolled item into that offense. Verify the item, substitute count, judgment and collateral consequences.
- PC § 1001.95 misdemeanor diversion granted — qualifying misdemeanor charge arising from unknowing possession; PC § 1001.95 motion filed and granted by court; program completed; charge dismissed; no felony conviction recorded
- Mental health diversion granted — defendant's anxiety disorder and specific emotional vulnerability in relationship with incarcerated family member contributed to charged conduct; PC § 1001.36 diversion pursued and granted; charge dismissed; treatment and support provided
- Firm-reported disposition: a knowledge challenge and search motion reportedly preceded a dismissal without plea. The actual criminal and immigration records must be reviewed before describing any continuing immigration consequence.
Client Feedback:
"I brought a bag to visit my brother in jail and had no idea it had drugs in it. David built the knowledge defense, showed I had absolutely no knowledge of what was inside, and the charge was dismissed. The prosecution couldn't prove I knew. I was terrified and David was the only one who explained I had a real defense." — Anonymous former client
"I was carrying my own prescription pain medication in my purse for a prison visit. I had no idea I wasn't allowed to have it or that it was a problem. David showed there was no criminal intent — I was just a patient with my medication. Charge dropped." — Anonymous former client
The preceding account is firm-published. A prescription may matter to section 4573.6 possession, but it does not alone authorize bringing medication into a facility under section 4573; compare actual staff authorization, the count and the court’s disposition.
"The officer searched my car in the jail parking lot before I even reached the entrance. David showed there was no probable cause for that search. The evidence was suppressed and the charge was dismissed completely." — Anonymous former client
"As a non-citizen, a conviction would have meant deportation. David challenged the knowledge element and filed a suppression motion simultaneously. The prosecution couldn't prove I knew about the drugs and the charge was dismissed without any plea. I am still in this country." — Anonymous former client
The preceding client account is firm-published and case-specific. A new case requires individualized immigration advice; the charge, substance, conviction record, status and potential relief matter, and dismissal does not guarantee no other immigration issue.
FREQUENTLY ASKED QUESTIONS
Is PC § 4573 always a felony?
Section 4573 is a felony charge in the cited statute. Other listed sections cover different items or conduct, and their charging classifications and sentencing rules must be read separately; no misdemeanor substitution follows automatically from a weak section 4573 case. Ask which subdivision, item, institution and lawful authorization are alleged, and whether another count is actually filed or offered.
What if I didn't know the drugs were in my belongings?
A genuine lack of awareness that a controlled substance was present can defeat a required knowledge element if the prosecution cannot prove it beyond a reasonable doubt. CALCRIM 2749 also asks whether the person knowingly brought or sent the item into the institution and knew its controlled nature; exact drug-name knowledge is not universal. Test bag ownership, handoffs, labels, statements and surveillance. For possession under CALCRIM 2748, control of the substance and awareness of its presence are separate elements.
Can prescription medication lead to PC § 4573 charges?
A prescription is not automatic permission to bring a controlled medication into a jail or prison. For section 4573, ask whether law or an authorized institutional official permitted bringing it in; for section 4573.6 possession, a valid prescription or facility authorization may be relevant under the current jury instruction. Obtain the original bottle, pharmacy and prescribing records, visitor instructions and any staff approval. Whether the prosecution can prove the charged elements and defeat an applicable defense is case-specific.
Can the search that discovered the substance be challenged?
A parking-lot search can be challenged when the facts support it, but location alone does not decide a warrant, consent, automobile-exception or facility-search issue. Review the stop and search sequence, posted notices, scope, who controlled the car and the evidence sought. Suppression removes only evidence covered by the ruling; dismissal is a later determination based on the remaining proof.
What are the immigration consequences of a PC § 4573 conviction?
Immigration consequences can be serious but are not identical for every section 4573 or related count. A federally controlled substance, the precise conviction record, any trafficking element, status and possible relief all matter. Simple misdemeanor labeling or a dismissed charge does not itself answer every immigration question. Seek case-specific advice before a plea rather than assuming mandatory removal or permanent bars.
Is diversion available?
Current Penal Code section 1000 is pretrial diversion for listed eligible offenses; it is no longer the old guilty-plea DEJ procedure and section 4573 is not automatically included. A different count might be eligible for misdemeanor, mental-health, military or local drug-court procedures, but each has separate statutory exclusions, court findings and program conditions. A proposed reduction or treatment referral does not promise dismissal or a clean record.
Are payment plans available?
Yes. The Law Offices of David Chesley offers flexible payment plans because cost should never be the reason someone charged with PC § 4573 goes without experienced legal representation. Call to discuss options during your free consultation.
Records that clarify a jail-entry or possession allegation
Which event is the prosecutor charging?
Section 4573 concerns bringing, sending or assisting an item into a penal institution or onto its grounds; section 4573.6 concerns possession there. A visitor found at an entrance, an inmate found inside and a person who sent a package may have different records and different elements to contest. Compare the complaint with the booking or visitor log, item location, alleged handoff and exact time. The facility’s name alone does not establish whether the particular place fits the instruction. Keep the original search and custody records for both distinct inquiries.
One more distinction matters for a visitor stopped before entry: section 4573 can cover bringing onto institutional grounds as described in CALCRIM 2749, so the defense should compare the precise boundary, vehicle location and access route rather than assume that “outside the building” ends the count. Section 4573.6 also names the grounds of a penal institution. Search authority and the criminal location element are different questions; winning one does not automatically decide the other.
What does “usable amount” require?
For a controlled substance, CALCRIM 2748 and 2749 include a usable-amount element when the optional drug elements apply. Useless traces or debris are different from an amount that can be used as a controlled substance; the amount need not be sufficient to intoxicate someone. Request the inventory, original packaging, photographs and complete testing report. If officers combined several items, ask which specific item the prosecution attributes to the defendant and whether jurors must agree on that item. Paraphernalia allegations use a different set of elements.
What can establish or dispute possession inside?
For section 4573.6, actual holding is one possible theory; the instruction also allows control or a right to control the item, personally or through another person. Two people can possess the same object, but presence in a shared cell or visitor area is not alone a substitute for proof of control and knowledge. Ask who could enter the area, who handled the container, what was said, whether there is video, and what institutional records show about custody of the item. The instruction also distinguishes mere drug use from possession.
How is authorization evaluated?
CALCRIM 2749 addresses a section 4573 defense when law, a person in charge, or a delegated official authorized bringing or sending the item. CALCRIM 2748 describes institutional-rule or official authorization for section 4573.6 possession and a valid-prescription defense when supported. Save visitor instructions, written permissions, staff names, prescription labels and records of medicine turned over at intake. Do not infer permission from a prescription alone, and do not infer criminal knowledge solely because a facility later rejected an item.
What happens if a search motion succeeds?
First identify what the motion targets: a traffic stop, vehicle, visitor screening, bag, cell or later laboratory search. The court decides standing, authorization or exception, and which evidence an order excludes. Witnesses, messages, video or an independently obtained sample may remain; an excluded item also may leave the charged count without necessary proof. The ruling and subsequent disposition answer whether the count is dismissed. A separate prison-discipline process, if any, is not automatically resolved by a criminal search motion.
What should counsel compare before a plea?
Ask for the exact charged subsection, the tested item and amount, each authorization or prescription record, and the proposed plea language. Compare jail-entry and possession charges separately, including any other item or count. For a noncitizen, the federally controlled substance and record of conviction may matter regardless of the state label; obtain qualified immigration review before accepting a “misdemeanor” or “no prison” description as protection. Any diversion proposal requires its own eligibility order, program conditions and recorded outcome.

Practical early steps are to obtain the complaint and booking papers, identify whether section 4573 or 4573.6 is charged, request preservation of visitor and search video if it exists, and gather prescription and authorization records. Those materials help evaluate knowledge, the nature of the item, institutional grounds, search scope and any proposed plea. Retention periods and available footage vary; no piece of evidence or deadline guarantees a defense result.
Don't plead guilty before every defense has been assessed. Don't assume the knowledge element is proven. Don't assume the search was valid. And don't wait. If you have been charged with bringing drugs into a jail, prison, or other custodial facility in California, call now.

"PC § 4573 requires proof that you knowingly brought a controlled substance into a custodial facility — not merely that one was found in your belongings. The knowledge and intent elements are frequently the most contestable parts of these cases. My commitment is developing the specific facts of what you actually knew and intended, challenging any unconstitutional search, and pursuing every available reduction or diversion pathway from the first day." — David Chesley, California Criminal Defense Attorney
The preceding attorney quotation is firm-supplied. CALCRIM 2749 requires the charged knowledge of bringing or sending and the controlled character or paraphernalia use; the prosecution need not prove knowledge of the precise chemical name in every case. Authorization and the charged institution or grounds must be assessed separately.
