What you must do

16 compliance obligations under this legislation — 6 can result in imprisonment.

Offences and prohibitions 15

Assist or induce a drug offence abroad

5 years imprisonment

If your business or you personally help someone commit a drug‑related crime in another country while you are in the UK, you commit a criminal offence under the Misuse of Drugs Act. A conviction can lead to an unlimited fine and possible imprisonment, and the matter will be dealt with by the Crown Court.

Any Person s.20 OPSS

Attempt or incite a drug offence

5 years imprisonment

If anyone connected with your business tries to carry out a drug‑related offence, or encourages someone else to do so, that conduct is a criminal offence. A conviction can lead to an unlimited fine and, in the most serious cases, imprisonment. The offence applies regardless of whether the underlying drug offence was actually completed.

Any Person s.19 OPSS

Breach drug regulations, licence conditions or give false information

2 years imprisonment

If you ignore any regulation made under the Misuse of Drugs Act, breach a condition of a drug licence, or knowingly give false or reckless information – for example when applying for or renewing a licence – you commit a criminal offence. Conviction can lead to a fine and/or imprisonment, although the exact penalties are set elsewhere in the Act. The offence applies to any person or business dealing with controlled drugs.

Any Person s.18 OPSS

Contravene a direction prohibiting prescribing or supply of controlled drugs

2 years imprisonment

If a doctor or pharmacist has been convicted of certain drug‑related offences, the Secretary of State can issue a direction that bars them from possessing, prescribing, supplying or otherwise handling the specified controlled drugs. Breaching that direction is a criminal offence. A conviction can lead to fines, imprisonment, or both, and the direction will be publicly recorded.

Any Person s.12 OPSS

Corporate liability for drug offences where directors consent or neglect

Unlimited fine

If your company commits an offence under the Misuse of Drugs Act (for example, producing, supplying or possessing a controlled drug) and a director, manager, secretary or similar officer allows it, turns a blind eye, or is negligent, both the company and that officer can be prosecuted. The company is treated as guilty of the same drug offence and will face the same penalties that apply to an individual offender. The exact fine or prison term will depend on the specific drug offence that has been committed.

Director/Officer s.21 OPSS

Fail to comply with directions for safe custody of controlled drugs

If the Secretary of State serves you a written direction requiring special precautions for storing controlled drugs at your premises and you do not follow it, you commit a criminal offence. Breaches can lead to prosecution, with the court able to impose a fine and/or imprisonment as appropriate.

Occupier s.11 OPSS

Forfeit assets linked to drug offences

If your company is convicted of a drug‑related offence under the Misuse of Drugs Act (or a related trafficking offence), the court can order any property that is connected to the offence to be taken away and either destroyed or dealt with as the court decides. The owner can only stop the order by applying to be heard and showing why the property should not be forfeited.

Any Person s.27 OPSS

Ignore a direction banning prescription of controlled drugs

Unlimited fine

If a doctor receives a direction that stops them from prescribing, supplying or authorising certain controlled drugs and they nevertheless do so, they commit a criminal offence. The offence applies to any medical practitioner who is served with such a direction under the Misuse of Drugs Act. Conviction can lead to an unlimited fine and, depending on the court, possible imprisonment.

Any Person s.13 OPSS

Intentionally obstruct a constable exercising drug search powers

If you deliberately prevent a police officer from searching for, detaining or seizing a temporary class drug, you commit a criminal offence. The offence applies to anyone – including businesses or their representatives – who intentionally interferes with the officer’s powers. Conviction can lead to a fine and/or imprisonment, although the exact penalties are set elsewhere in the Act.

Any Person s.23A OPSS

Obstruct or fail to produce evidence to drug enforcement officials

If police or OPSS officers search your premises or ask you to produce books, documents or stock of controlled drugs, you must cooperate. Intentionally obstructing them, hiding evidence, or refusing to produce the requested material without a reasonable excuse is a criminal offence. Conviction can lead to a fine and/or imprisonment.

Any Person s.23 OPSS

Permit production, supply or use of controlled drugs on premises

If you own, occupy or manage a property and you knowingly allow anyone to produce, supply, prepare or smoke controlled drugs such as cannabis, cannabis resin or opium on that property, you commit a criminal offence. A conviction can result in an unlimited fine and/or a term of imprisonment, depending on how the case is tried.

Occupier s.8 OPSS

Possess a controlled drug without authority

5 years imprisonment

If you or your business have a controlled drug in your possession without the proper authorisation, you are committing a criminal offence. The offence applies even if the drug is held for legitimate business purposes but the necessary licence or exemption is missing. On conviction you face an unlimited fine and up to five years’ imprisonment.

Any Person s.5 OPSS

Produce or supply a controlled drug without authority

Unlimited fine

If your company produces a controlled drug, or supplies (or offers to supply) a controlled drug in breach of the Misuse of Drugs Act 1971, you are committing a criminal offence. A conviction can result in an unlimited fine and may also carry a term of imprisonment, with the case normally heard in the Crown Court.

Any Person s.4 OPSS

Supply equipment for unlawful drug use

Unlimited fine

If you supply, or offer to supply, any item that could be used to give or prepare a controlled drug – such as pipe‑heads, filters, or mixing kits – and you know it will be used illegally, you commit a criminal offence. The same applies to items used to prepare the drug itself. Supplying a hypodermic syringe is expressly exempt. A conviction can bring an unlimited fine and/or imprisonment.

Any Person s.9A OPSS

Use, possess or facilitate opium smoking

Up to 5 years imprisonment

If a person smokes prepared opium, visits a place used for opium smoking, or holds pipes, utensils or other equipment used for smoking or preparing opium, they commit a criminal offence. Conviction can result in an unlimited fine and a custodial sentence (up to several years). The offence can be tried either in the Magistrates' Court or Crown Court, depending on the seriousness.
