Being accused of supplying drugs, or being concerned in the supply of drugs, is one of the most serious allegations under the Misuse of Drugs Act 1971. The stakes are high, and the prosecution builds its case on drugs, cash, telephones, and messages. At Woolfe & Co Solicitors, our solicitors for drug supply and being concerned in supply build careful, evidence-led defences. Whether you need a supply offence lawyer who understands phone downloads or a criminal defence solicitor ready to challenge the search, we stand ready. We are available 24 hours a day, seven days a week, across England and Wales.
Being concerned in the supply of drugs is an offence under Section 4(3)(b) of the Misuse of Drugs Act 1971. In simple terms, it applies where you knowingly took part in arrangements relating to the supply of a controlled drug, even if you never held the drugs yourself.
The full offence of "being concerned in the supply of a controlled drug to another" is distinct from straightforward possession or direct supplying. Our solicitors for drug supply and being concerned in supply cases explain that the prosecution must prove you were knowingly involved in a supply arrangement, whether by helping to sell, storing, conveying, funding, or otherwise facilitating the transfer of a controlled drug.
Where our criminal defence lawyers defend a direct supply allegation, the focus is on whether you actually supplied or offered to supply a drug. For a being concerned in supply charge, the court looks at the wider arrangement, including cash, telephones, data, and the accounts of other people. A skilled supply drugs lawyer will challenge every element of that evidence.
To secure a conviction, the Crown must prove beyond reasonable doubt that you knew a controlled drug was involved and that you intentionally took part in an arrangement connected to its supply. Evidence is often circumstantial, drawn from phone data, cash, and witness accounts, which means there is always room for an experienced solicitor to challenge it.
Direct supply, under Section 4(3)(a), means actually supplying or offering to supply a controlled drug. Being concerned in supply, under Section 4(3)(b), covers the wider supporting role. A person can be charged where they never touched the drug, and this makes the choice of lawyer critical.
The possible sentence for a drug supply offence depends on the class of the drug involved. The table below sets out the maximum penalties a court can impose in England and Wales.
| Drug Class | Examples | Maximum Penalty for Supply |
|---|---|---|
| Class A | Heroin, cocaine, crack cocaine, ecstasy (MDMA), LSD, methamphetamine, magic mushrooms | Up to life imprisonment, an unlimited fine, or both |
| Class B | Cannabis, ketamine, synthetic cannabinoids, amphetamine | Up to 14 years imprisonment, an unlimited fine, or both |
| Class C | Anabolic steroids, GHB, benzodiazepines, some tranquillisers | Up to 14 years imprisonment, an unlimited fine, or both |
In our day-to-day defence practice we have seen how a robust case can make the difference between a charge being dropped, a lesser plea being accepted, or a sharp reduction in sentence. A drug supply allegation is never simply about the drugs found, and expert representation from a specialist supply drugs solicitor matters at every stage of the case.
Every supply case is different, and our criminal defence lawyers tailor each defence to the specific facts. We look beyond the headline allegation and scrutinise the way the evidence was gathered and how it is being used against you.
If the police searched you or your home unlawfully, or acted outside their powers, we can argue the evidence should be excluded at court. Many supply cases rest on whether a search was lawful in the first place.
There is no supply without a controlled drug and an intention to supply. We challenge the inference drawn from quantities, cash, messages, and packaging, and we look for an innocent explanation for your involvement.
Digital evidence is central to most being concerned in supply cases. We examine extraction reports, message threads, and metadata for breaches of procedure and for weaknesses the court can rely upon.
A police interview under caution is where many drug supply cases are won or lost. We attend with you, advise you on what to say, and protect you from making admissions under pressure. Never attend a drugs interview without a solicitor.
We attend the police station at any hour, free of charge, and make representations to the custody officer. Whether you face a voluntary interview or arrest, we ensure the police follow procedure from the start.
From the first Magistrates Court hearing through to trial and sentencing at the Crown Court, our team prepares every case thoroughly and advocates for the best possible outcome for you.

These are the questions clients ask us most about drug supply and being concerned in supply charges. Every answer below reflects the way our drug supply solicitors and criminal defence lawyers handle real cases.
Being concerned in the supply of drugs is an offence under Section 4(3)(b) of the Misuse of Drugs Act 1971. It covers anyone who assists in or facilitates a drug supply arrangement, even without direct possession, such as helping to sell, transport, or arrange a supply deal. Our defence solicitors will examine the evidence against you to challenge any allegation.
Supplying or being concerned in the supply of Class A drugs such as heroin, cocaine or ecstasy carries a maximum penalty of life imprisonment and an unlimited fine. Class B and Class C supply offences carry up to 14 years imprisonment. A specialist supply drugs lawyer can make submissions that reduce the starting point sentence.
Yes. The offence of being concerned in supply can apply even where you never held the drugs yourself. If you helped organise, fund, transport, or arrange a supply, the prosecution may still argue that you were concerned in the supply. Our solicitors will test whether the evidence properly proves your knowing involvement.
Supply offences carry high maximum penalties, but the actual sentence depends on the quantity, your role, the evidence, and your personal circumstances. An experienced defence lawyer can build a defence that may see the charge reduced or the sentence lowered, or achieve acquittal altogether.
Common defences include challenging whether you knew about the supply, disputing the evidence of your involvement, arguing a lawful excuse, and challenging the lawfulness of searches, seizures, or phone downloads that produced the prosecution evidence.
Police station attendance for a drugs matter is always free regardless of your income. For court proceedings, legal aid may be available subject to a means test and the interests of justice. We are SRA-regulated and can advise on both legal aid and private funding options from the very start.
