Drug possession and drug supply are separate offences, and the difference can have a major effect on the seriousness of a case. Someone found with a controlled drug may face a possession allegation, but the prosecution can consider a more serious charge if there is evidence that the person intended to supply the drug to someone else.

Simple possession is covered by section 5(2) of the Misuse of Drugs Act 1971. Possession with intent to supply is covered by section 5(3), while actual supply or an offer to supply is covered by section 4(3). Supply does not require proof of payment or profit.

How is intent to supply established?

The prosecution may rely on direct evidence, such as admissions or witness evidence, but intent can also be inferred from surrounding circumstances. The CPS identifies factors including a quantity that appears inconsistent with personal use, uncut or unusually pure drugs, a variety of drugs, drugs divided into sale-sized packages and equipment such as scales or packaging materials.

These factors are not automatic proof of supply. Their meaning depends on the whole case. For example, the presence of cash or packaging may be capable of more than one explanation. A defence can challenge the prosecution's interpretation and argue that the evidence does not establish an intention to supply beyond reasonable doubt.

Why the distinction matters

The maximum penalties for simple possession are lower than those for supply or possession with intent to supply. For Class A possession, the statutory maximum is seven years' custody; Class B possession carries a maximum of five years; and Class C possession carries a maximum of two years. By contrast, supply and possession with intent to supply can carry a maximum of life imprisonment for Class A drugs and 14 years for Class B or C drugs.

The actual sentence can be much lower than the statutory maximum and depends on the guideline and facts of the case. Courts consider the class of drug and, for the more serious offences, factors such as quantity, harm and culpability.

What evidence can make a difference?

Police may examine the drugs themselves, packaging, phones, messages, financial information, CCTV and witness accounts. The defence may need to consider whether the evidence has been interpreted correctly, whether the prosecution can prove the required intention and whether there is an alternative explanation for the circumstances.

If you are facing a possession allegation, do not assume that the case will automatically remain a simple possession matter. Equally, an allegation of intent to supply still has to be proved. The precise evidence and charge should be examined carefully.
