Misuse of Drugs Act Offences and Sentences (UK)
Last reviewed: June 2026. General information about the law in England and Wales, not legal advice; sentencing depends on the facts and the current Sentencing Council guideline.
In short: drug offences in the UK are governed by the Misuse of Drugs Act 1971, which sorts controlled drugs into Class A, B and C. The penalty depends on the class and on whether it is possession or supply/production. Possession of Class A can mean up to 7 years (though lower-level possession is often a caution, fine or community order); supplying or producing Class A can mean up to life imprisonment. Class B and C carry lower maximums. Actual sentences follow the Sentencing Council drug-offences guideline and depend on the drug, the quantity and your role.
The drug classes
Drugs are classified by harm: Class A (e.g. heroin, cocaine, ecstasy, LSD), Class B (e.g. cannabis, ketamine, amphetamines) and Class C (e.g. some tranquillisers and anabolic steroids). The class largely sets the maximum penalty.
Maximum penalties
| Offence | Class A | Class B | Class C |
|---|---|---|---|
| Possession | Up to 7 years + fine | Up to 5 years + fine | Up to 2 years + fine |
| Supply / production | Up to life + fine | Up to 14 years + fine | Up to 14 years + fine |
Possession with intent to supply is treated as supply. Courts use the Sentencing Council guideline, which weighs the quantity and your role (leading, significant or lesser) to set the sentence within these maximums. See our guide to possession vs dealing for how intent is judged.
What usually happens in practice
Lower-level possession for personal use is frequently dealt with by a caution, a fine or a community order rather than prison — especially for a first offence with a small quantity. Supply and production, and large-scale or organised dealing, are treated far more seriously and routinely attract immediate custody. The courts can also make confiscation orders to recover the proceeds.
Common misunderstandings
- Thinking possession always means prison — lower-level possession often results in a caution, fine or community order.
- Assuming cannabis is not serious — supply of Class B can still mean up to 14 years.
- Not realising “intent to supply” is judged on quantity, scales, cash and messages, not just an admission.
- Believing the maximum is typical — sentences depend heavily on role and quantity.
