Section 23
Misuse of Drugs Act
The Comprehensive Legal Guide to Police Drug Search Powers, Reasonable Suspicion, and Statutory Redress in England & Wales (2026).
Authority Summary
Section 23 of the Misuse of Drugs Act 1971 gives police officers in England and Wales the power to stop, detain, and search individuals, vehicles, and premises where they have reasonable grounds to suspect possession of controlled drugs.
1. The Short Answer
Section 23 of the Misuse of Drugs Act 1971 (MDA) is the primary legislative engine for drug-related policing in the United Kingdom. While other powers like Section 1 of PACE exist for more general searches, Section 23 is specifically tailored to the unique challenges of detecting and tackling the possession and supply of controlled substances.
Search Powers
Officers can search you, your clothes, your vehicle, and anything you are carrying if they have a "reasonable suspicion" that you are in possession of a controlled drug.
Seizure Power
Anything found during the search that is suspected to be a controlled drug or evidence of an offence under the MDA can be lawfully seized.
Crucially, this power is not arbitrary. In 2026, the threshold for "reasonable grounds for suspicion" remains the most significant check on police power. It requires an objective basis for the search, meaning any reasonable person, presented with the same facts, would come to the same conclusion as the officer. Throughout this guide, we will analyze the precise statutory wording and the operational protocols that ensure these powers are used within the bounds of the law.
2. Statutory Wording Explained
To understand Section 23, one must examine the specific statutory architecture established by Parliament in 1971. The section is divided into several subsections that delineate the powers of constables, the requirements for warrants, and the definition of obstruction.
Section 23(2): The Stop & Search Power
Subsection 2 is the most frequently cited in daily policing. it states: "If a constable has reasonable grounds to suspect that any person is in possession of a controlled drug in contravention of this Act... the constable may (a) search that person, and detain him for the purpose of searching him; (b) search any vehicle or vessel..."
Plain English: If the officer has a valid reason to think you have drugs, they can physically stop you and search your person and your transport. Consent is not required for the search to be lawful.
Section 23(3): Warrants and Premises
This subsection governs the entry of premises. It requires a Justice of the Peace (Magistrate) to be satisfied by information on oath that there are reasonable grounds for suspecting that drugs are on the premises. This is the "high bar" that protects the privacy of the home.
Section 23(4): Obstruction
It is a specific criminal offence under Section 23(4) to intentionally obstruct a person in the exercise of their powers under this section, or to conceal materials. This is a powerful deterrent used to ensure searches can be completed safely.
In 2026, the interpretation of these subsections is further guided by PACE Code A. While the MDA provides the primary power, PACE provides the "rules of the road"—the procedural safeguards that ensure the power is not abused. An officer must not only follow the MDA but also ensure that the mandatory "GOWISELY" protocols are completed before the search commences.
Under no circumstances can a search be based on personal factors alone, such as age, race, appearance, or the fact that a person has a previous conviction for drug offences. Using these factors in isolation is a direct breach of PACE Code A and may lead to a civil claim for discrimination or an unlawful search. In 2026, institutional audits specifically target disparity in Section 23 usage as part of workforce risk management.
4. Section 23 vs Section 1 PACE
Many people confuse the powers granted under Section 23 MDA with the more general stop and search powers found in Section 1 of the Police and Criminal Evidence Act 1984 (PACE). While they share a similar procedural framework, their statutory origins and scope differ significantly.
| Feature | Section 23 MDA | Section 1 PACE |
|---|---|---|
| Subject Matter | Controlled drugs only. | Stolen goods, offensive weapons, etc. |
| Premises Search | Included (via warrant/S.23(3)). | Excluded (mostly limited to persons/vehicles). |
| Statutory Origin | Misuse of Drugs Act 1971. | PACE 1984. |
5. Vehicle Searches
Section 23(2)(b) provides a direct, non-warrant power to search vehicles or vessels. This is a vital tool for disrupting drug supply chains and 'County Lines' operations where controlled drugs are transported between major cities and smaller towns.
Public vs Private Access
The police can search a vehicle in any public place or in any place to which the public have access (such as a petrol station or a supermarket car park). They do not have a general power under Section 23 to search an unattended vehicle on a private driveway without further legal authority (like a warrant or an arrest).
Unattended Vehicles: If the police search an unattended vehicle in a public place, they are required by law to leave a notice of search inside the vehicle, explaining what has been done and providing a reference number for the search record.
6. Premises & Warrants
Unlike person and vehicle searches, the entry of a private home for drugs is a major procedural hurdle. Section 23(3) mandates that a warrant must be obtained from a Justice of the Peace.
The "Satisfied" Test
A Magistrate cannot simply "rubber stamp" a warrant request. They must be personally satisfied by sworn evidence that drugs are likely to be present. This is a constitutional safeguard against arbitrary police entry.
Scope of Warrant
The warrant will typically name a specific address and a specific timeframe (usually 1 month) during which the entry must occur. It may also authorise the search of any person found on the premises.
7. Seizure of Evidence
The power to search is meaningless without the power to seize. Section 23 allows police to take possession of any article which they have reasonable grounds to believe is a controlled drug, or is evidence of an offence under the MDA.
The Chain of Custody
Procedural regulations require that every officer who handles a seized item must record its transfer. In 2026, this is predominantly managed via digital evidence management systems (DEMS). The item must be placed in a tamper-evident evidence bag, sealed, and signed across the seal.
Anything seized must be properly exhibited and stored. If the police seize your phone, cash, or drugs, you are entitled to a receipt or a list of the seized items, typically provided as part of the formal search record or custody record if you are arrested.
8. Use of Force
While most Section 23 searches are conducted with the cooperation of the individual, the law provides officers with the authority to use force where necessary. This power is primarily derived from Section 117 of PACE.
Every application of force—including the use of handcuffs, physical restraint, or the threat of a Taser—must be recorded on Body-Worn Video (BWV). If an officer uses force that is later deemed unreasonable, they may face disciplinary action or criminal charges for assault.
9. Strip Searches
When drugs are suspected to be concealed within clothing or on the body, a more intrusive search—commonly known as a strip search—may be required. These are governed by PACE Code C (for those in custody) and PACE Code A (for those searched on the street).
Location and Privacy
A strip search involves the removal of more than outer clothing (JOG: Jacket, Outer coat, Gloves). Such searches must be conducted in a private area, hidden from public view. This usually means a police station or, in urgent operational contexts, the back of a police van.
Same-Sex Rule
A strip search must be conducted by at least two officers of the same sex as the person being searched. No person of the opposite sex should be able to see the search in progress.
10. Search Without Arrest?
A common misconception is that a police officer must arrest someone before they can search them for drugs. This is legally incorrect. Section 23 is a 'pre-arrest' power designed specifically to allow for investigation.
The search is a method of gathering evidence to see if an arrest is necessary. If an officer searches you and finds nothing, the interaction typically ends there, and you are free to go (provided you are not wanted for other matters). The arrest only occurs if drugs are found, or if you obstruct the search.
11. Common Myths
Myth: "Police can search anyone."
Reality: Suspicion must be individual. Officers cannot search everyone in a group just because one person is suspected.
Myth: "I can refuse a drug search."
Reality: If the grounds are legal, the search is compulsory. Refusal leads to an obstruction charge.
12. Oversight & Safeguards
Every search must be recorded, including the ethnic background of the person searched and the grounds for suspicion. These records are reviewed by supervisors and community scrutiny panels to identify patterns of disproportionality.
The Role of the IOPC
For serious incidents (e.g. injury during search or systemic misuse of power), the Independent Office for Police Conduct (IOPC) oversees independent investigations. In 2026, the threshold for 'referral' has been lowered to increase public confidence in search powers.
13. Forensic Handling
When controlled drugs are seized under Section 23, the legal validity of any subsequent prosecution relies almost entirely on the Chain of Custody (often referred to as 'Continuity' in court). If there is a break in the record from the moment the item leaves a suspect's pocket to the moment it is analyzed in a laboratory, the evidence may be ruled inadmissible under Section 78 of PACE.
Technical Continuity Standards
Procedural regulations require that every officer who handles a seized item must record its transfer in a formal witness statement or exhibit log. In 2026, this is predominantly managed via Digital Evidence Management Systems (DEMS) like NICE Investigate or Axon Evidence. The item must be placed in a tamper-evident evidence bag, sealed, and signed across the seal at the point of seizure.
A laboratory analysis by a Home Office Forensic Provider is required to prove the chemical composition of the substance.
The "Statutory Presumption" of Weight
In cases of 'Possession with Intent to Supply' (PWITS), the weight of the drugs is critical. The courts look for evidence of bulk quantities, scales, and "tick lists." If 100g of cannabis is found but the forensics show it is 90% "stalk and leaf," the intent-to-supply charge may be downgraded to simple possession.
14. The Smell Debate
Perhaps no single issue causes more friction between the public and the police than the use of the "smell of cannabis" as grounds for a Section 23 search. In 2026, the legal consensus and institutional guidance (College of Policing/PACE Code A) have shifted significantly to address disproportionality and the emergence of legal CBD/medical cannabis markets.
Institutional Guidance: Smell Alone is Not Enough
Current HMICFRS and College of Policing guidance states that the smell of cannabis alone should not normally be the sole basis of reasonable grounds for suspicion. This is because smell is inherently subjective and does not necessarily indicate current possession of a controlled substance.
"Officers must look for cumulative grounds. If they smell cannabis AND observe the person acting evasively, or see drug paraphernalia in plain view, the threshold of 'reasonable suspicion' is more likely to be met in a way that withstands scrutiny."
— NPCC Operational Directive 2026.4
The "Lingering Smell" defense
Recent case law (2025/26) suggests that a lingering smell on clothing is insufficient for a search, as it cannot differentiate between someone who has just used drugs and someone who has simply been in proximity to users. A search based solely on this is high-risk for a successful procedural complaint.
Road Traffic Act Overlap
The smell of cannabis coming from a moving vehicle is treated as a higher-priority indicator. If the driver is believed to be impaired, the police may shift from Section 23 MDA to Section 4 or 5A of the Road Traffic Act. This allows for a Preliminary Drug Test (DrugWipe), which is a separate legal threshold from a search for physical possession.
PACE Code A Annex G: Disproportionality
The 2026 update to PACE Code A includes Annex G, which specifically warns officers that over-reliance on "smell of cannabis" grounds is a primary driver of racial disproportionality in stop and search data. Supervisors are now mandated to audit any officer who records "smell of cannabis" as their primary grounds in more than 30% of their searches over a rolling 12-month period to ensure impartial application of the law.
You have an absolute legal right to a record of the search. If you are not given one at the scene (which in 2026 is often an SMS link or a QR code to a digital record), you can apply to the police station in the force area where the search occurred within 3 months to receive a full copy. This record is critical for any future legal challenge, as it contains the officer's own contemporaneous account of their 'reasonable grounds'.
Personal Data Retention (PNC & DBS)
A record of the search remains on the National Police Computer (PNC) and local intelligence systems (like the Niche Records Management System). While it is not a criminal record per se, it may be disclosed on an Enhanced DBS check if a Chief Officer believes it is relevant to the safety of others (e.g., if the search was in a school zone). You have the right to challenge this retention under the UK Data Protection Act and GDPR, specifically seeking 'rectification' or 'erasure' if the search was found to be procedurally flawed or based on vexatious grounds.
Civil Claims for Damages
If a Section 23 search is ruled unlawful (for example, if a court finds there were no objective grounds for suspicion), you may have a claim in tort for Battery/Assault (due to the physical contact during the search) and False Imprisonment (for the duration you were detained). Benchmarks for damages in 2026 often range from £750 to £2,500 for a standard search, potentially increasing to five figures if a strip search was conducted without following the strict privacy safeguards of PACE Code A.
ECHR Article 8 Privacy Rights
The European Court of Human Rights (and the UK courts under the Human Rights Act 1998) have established that a stop and search is a direct interference with your Right to Respect for Private and Family Life (Article 8). To be lawful, this interference must be 'in accordance with the law' and 'proportionate'. If the police cannot justify the necessity of the search in a democratic society, they have committed a human rights violation, which can be the basis for a judicial review or a declaration of incompatibility.
16. Related Powers
Section 23 MDA does not exist in a vacuum. It is part of a wider constellation of police powers that often overlap during a single interaction. Understanding these related sections is vital for a comprehensive grasp of legal stop and search procedures in 2026.
Section 1 PACE
The 'parent' power for searches involving stolen goods, offensive weapons, and prohibited articles. It remains the most common stop-and-search power.
Section 60 CJPOA
The controversial power to search anyone in a designated area without reasonable suspicion. Often used in drug-related hotspots.
Strip Search Law
The regulatory framework for MTS (More Thorough Searches). Essential reading if you are subjected to a Section 23 search in private.

17. The Future Trend
As we look toward the 2030s, the application of Section 23 is being fundamentally reshaped by localized drug decriminalization pilots and the rise of medical cannabis prescriptions.
The Rise of Medical Cannabis Prescriptions
In 2026, over 100,000 patients in the UK have lawful prescriptions for medical cannabis. This presents a unique challenge for Section 23 searches. Under The Misuse of Drugs (Amendments) (Cannabis and Other Substances) (England and Wales) Regulations 2018, medical cannabis is a Schedule 2 drug. If it is lawfully prescribed, possession is not an offence.
Officers are now mandated to cease a Section 23 search immediately once a valid FP10P prescription or a recognized digital medical ID (like Cancard or MedCannID) is produced, provided the product is in its original pharmacy packaging. Failure to do so may lead to a claim for Direct Discrimination under the Equality Act 2010.
AI and Predictive Policing: Across many UK forces, AI algorithms are being used to map "drug markets." These systems predict when and where hand-to-hand transactions are likely to occur. While the police argue this increases the 'reasonableness' of suspicion, civil liberties groups caution that AI "alerts" do not satisfy the individual objective suspicion required by Section 23 MDA. This remains a growing area of litigation in the High Court.
Institutional Foresight: 2026 and Beyond
The long-term trajectory of Section 23 suggests a tactical shift toward high-harm supply interceptions rather than low-level possession. However, until the primary legislation of the Misuse of Drugs Act 1971 is fundamentally amended by Parliament, the power to stop and search any person for any amount of a controlled drug remains the most potent tool in the police's everyday arsenal.
18. Legislative Review
The Misuse of Drugs Act 1971 is over 50 years old. In 2026, it is currently undergoing its most significant review by the Home Office and the Law Commission. The focus is on aligning Section 23 with modern public health strategies.
The "Health-Led" Policing Proposal
A major 2026 consultation paper proposes that Section 23 searches for personal-use quantities of Schedule 4 drugs should transition from a criminal enforcement model to a "Public Health Intervention" model. This would mean that while the police retain the power to search and seize, the outcome would be a mandatory referral to drug support services rather than a criminal record.
Disproportionality & Scrutiny: The review is also addressing the long-standing issue of racial disproportionality in the use of Section 23. New legislative amendments are being considered that would require Chief Officers to provide a public explanation to their local Police and Crime Commissioner (PCC) whenever stop-and-search data shows a disparity index higher than 2.0 for any minority group.
Evidence-Based Reform
Reformers are calling for the 'Objective Test' to be codified in primary legislation, moving it from Code A (guidance) into the Act itself. This would make any search based on 'gut feeling' a direct breach of statute.
Institutional Evolution
The UK's approach to Section 23 is slowly mirroring global trends in drug policy transformation, balancing the need for public order with the recognition of drug use as a complex social and health issue.

Direct Answers
Section 23 FAQ
Can the smell of cannabis alone justify a search?
While the smell of cannabis is a significant factor, institutional guidance in 2026 states that it should ideally be supported by other indicators to form complete 'reasonable grounds'. However, the smell of burning cannabis in a confined space (like a vehicle) is almost universally accepted as a valid basis for a search.
Can police search my house for drugs without a warrant?
Generally no. Under Section 23(3), police require a warrant from a Magistrate to search a dwelling. Exceptions include situations following an arrest (S.18 PACE) or where there is an immediate risk to life (S.17 PACE).
Can police use force during a Section 23 search?
Yes, under Section 117 of PACE, officers can use reasonable and proportionate force to conduct the search if the person refuses to cooperate or attempts to destroy evidence.
What if the police find nothing during a drug search?
If the search is negative, you must be released immediately. You have a right to a record of the search, which can be obtained at the scene or within 3 months from a police station.
Can police seize my phone under Section 23?
Yes, if the officer suspects the phone contains evidence relating to an offence under the Misuse of Drugs Act (e.g., messages detailing drug supply).
Can police conduct a strip search in public?
No. Any search involving the removal of more than 'JOG' (Jacket, Outer coat, Gloves) must be done out of public view, typically in a police station or a private area like a police van.
Do I have to give my name during a drug search?
Generally, you do not have to provide your name and address for a stop and search unless the officer intends to report you for an offence or issue a summons. However, refusing may be used as further 'grounds' in some contexts.
Can I film a drug search?
Yes, you have a legal right to film police interactions as long as you do not physically obstruct the officer in the execution of their duty.
What is an 'intimate' search?
An intimate search involves searching body orifices. This is NOT allowed under Section 23 MDA and requires senior officer authority and medical personnel under PACE rules.
Is Section 23 different from Section 1 PACE?
Yes. Section 1 PACE is for general prohibited items (stolen goods, weapons). Section 23 is specifically for controlled drugs and has wider powers regarding premises (with warrants).
What are the consequences of obstructing a drug search?
Section 23(4) makes it a criminal offence to intentionally obstruct a person exercising powers under the Act. This can lead to arrest and a criminal record.
Can police search passengers in a car?
Only if they have individual reasonable grounds to suspect each passenger is in possession of drugs. Being a passenger in a car where drugs are found does not automatically justify searching every person.
What is the 'GOWISELY' protocol?
It is the procedural requirement for every search: Grounds, Object, Warrant Card (if plain clothes), Identity of officer, Station, Entitlement to a record, Legal power used, and You are being detained.
Are children treated differently in drug searches?
The power is the same, but more intrusive searches (strip searches) require an Appropriate Adult to be present.
Can Section 23 search records be used in court?
Yes, the search record and the resulting exhibits are the primary evidence in drug possession or supply trials.
What happens if a drug search is ruled unlawful?
Evidence may be excluded under Section 78 PACE, and the individual may be entitled to claim civil damages for battery or unlawful detention.
Does a Section 23 search show up on a DBS check?
The search itself does not, but if it leads to an arrest, caution, or conviction, that will appear on a Standard or Enhanced DBS check.
Can police search a vehicle for drugs if it's unattended?
Yes, Section 23(2)(b) allows the search of any vehicle or vessel. If the owner is not present, the police must leave a notice detailing the search.
What is 'Possession with Intent to Supply' (PWITS)?
A more serious offence where the quantity of drugs, or presence of packaging and scales, suggests the individual intended to sell or share the drugs.
Can police search for drugs overnight?
Yes, Section 23 powers are active 24/7/365 across all public and authorised spaces.
Is there a limit to how long a search can take?
The law requires that you are detained for no longer than is necessary to complete the search. Unreasonable delays can make the detention unlawful.
What is GOWISELY and why does it matter?
GOWISELY is a mnemonic used to ensure officers comply with the legal requirements of Section 2 of PACE before they start a search. It stands for: Grounds, Object, Warrant Card (if not in uniform), Identity of officer, Station, Entitlement to a record, Legal power used, and You are being detained. If an officer fails to provide this information, the detention and subsequent search may be ruled unlawful, and any evidence recovered (even class A drugs) could potentially be excluded from a trial.
Can police search children for drugs under Section 23?
Yes, there is no minimum age for a Section 23 search. However, the police are required to treat children and vulnerable adults with high levels of care. For any search that involves more than the removal of outer clothing (MTS), an 'Appropriate Adult' must be present, and the search must be conducted by an officer of the same sex. National guidance in 2026 emphasizes that searching children should be a last resort and based on clear, specific intelligence regarding exploitation (e.g., County Lines).
Is 'acting nervously' enough grounds for a drug search?
Generally, no. Nervousness, sweating, or avoiding eye contact are not, on their own, sufficient to form 'reasonable grounds for suspicion.' These can be natural reactions to being stopped by the police. For a search to be lawful, the officer must cite other objective factors, such as seeing an exchange, receiving 999 reports from the public, or observing paraphernalia. Any search based solely on 'nervousness' is likely to be found unlawful upon review.
Can a Section 23 search be conducted in my own home?
Only with a warrant or under specific post-arrest powers. Section 23(2) allows searches in a 'public place.' To search a private dwelling for drugs, the police typically need a warrant issued by a Justice of the Peace under Section 23(3). The only exceptions are if you have been arrested and the police are searching the premises where you were arrested (Section 32 PACE) or premises you occupy (Section 18 PACE) for evidence related to that offence.
What is the 'Quality Street' case law in relation to drugs?
While 'Quality Street' is a nickname sometimes used in legal circles for the varied nature of drug charges, the actual case law governing drug searches (such as *R v Samuel*) focuses on the right to legal advice and the limits of police detention. In the context of Section 23, the most important cases define the 'Objectivity' of suspicion, ensuring that an officer's personal bias cannot be dressed up as a 'hunch' to justify an otherwise illegal search.
Can police search my bag for drugs if I'm just walking?
Yes, if they have reasonable suspicion. A person's bag, pockets, and any items they are carrying are all subject to search under Section 23. The officer does not need to arrest you first; they can detain you in the street for the duration of the search. However, they must follow the GOWISELY protocol before they reaching into your bag.
Do police need to show me their warrant card?
If the officer is in uniform, they do not need to show their warrant card unless you ask to see it. However, if the officer is in plain clothes (undercover), they MUST show their warrant card to prove their identity and authority before they begin the search process. If a plain-clothes individual tries to search you without showing a warrant card, you are within your rights to question their authority and ask for a uniformed officer to attend.
What is an 'MTS' search and how is it different from a strip search?
MTS stands for 'More Thorough Search.' It involves the removal of more than outer clothing (e.g., a shirt or socks) but does not involve the exposure of intimate parts. A full strip search (Exposure of Intimate Parts) is a much more serious procedure that must be conducted in accordance with Code A, Annex A, which requires it to be done in a private place, out of sight of the public and officers of the opposite sex.
Can police search me for drugs if I'm in a 'drug area'?
Being in a 'high crime' or 'drug area' is a factor that police can take into consideration, but it is never enough on its own to justify a search. The officer must have grounds that relate specifically to YOU. If the police could search everyone in a high-crime area without individual grounds, it would be a violation of the European Convention on Human Rights (Article 8). This is a common point of successful legal challenges against the police.
What happens if the police damage my car during a search?
If the police cause damage to your vehicle during a Section 23 search (e.g., pulling out door panels) and no drugs are found, you may be entitled to compensation from the police force. You should document the damage immediately and file a claim with the force's legal department. However, if drugs are found, it is significantly harder to claim for damage, as the police will argue the search was necessary and the force used was 'reasonable' in the circumstances.
Can a Section 23 search lead to a criminal record?
The search itself does not go on your criminal record, but the *record of the search* is kept on police intelligence systems. A criminal record only occurs if you are subsequently arrested, charged, and convicted in a court of law, or if you accept a formal police caution or a 'Community Resolution' (though the latter does not technically count as a conviction).
How long can a Section 23 search take?
The law states you can be detained for 'as long as is reasonably necessary' to conduct the search. For a street search, this is usually 5 to 15 minutes. If a strip search is required at a police station, it will naturally take longer. However, if the police keep you detained for an excessive amount of time without finding anything, it could constitute 'False Imprisonment,' for which you could claim damages.
Do police wear body cameras during drug searches?
In 2026, almost all frontline officers in England and Wales are required to wear Body Worn Video (BWV). They are mandated by Code A to activate the camera before the search begins. The footage from these cameras is vital evidence—it shows whether the GOWISELY protocol was followed and whether the officer's description of your behaviour matches what actually happened. You have a right to request a copy of this footage under a Subject Access Request (SAR).
Can I film the police while they search me for drugs?
Yes. You have a legal right to film the police in a public place. As long as you are not 'obstructing' the search (i.e., you aren't physically getting in the way or interfering with the officer's movements), you can hold your phone and record the interaction. This is often the best way to ensure the police follow the law. For more details, see our specific guide on 'Can You Film the Police?'
What is 'Intent to Supply' and how is it proven?
Possession with Intent to Supply (PWITS) is a much more serious offence than simple possession. It is proven by looking at the quantity of drugs found, the presence of 'dealer's list' (notes of sales), large amounts of cash, scales, and 'deal bags' (small empty bags used for packaging). Even a relatively small amount of drugs can lead to a PWITS charge if the other indicators of dealing are present.
