No, weed is not legal in Scotland. Cannabis is a Class B controlled drug under the Misuse of Drugs Act 1971, a UK-wide law that applies across Scotland, and possessing, growing, or supplying it is a criminal offence.1Legislation.gov.uk. Misuse of Drugs Act 1971, Schedule 2 That said, Scottish police and prosecutors deal with most personal-use cases outside the courts, and the practical consequences of being caught with a small amount are usually lighter than the headline penalties suggest.
Drug law is reserved to the UK Parliament, so the Scottish Government cannot change cannabis’s legal status on its own, even though it controls healthcare and criminal justice policy.2UK Parliament Commons Library. General Debate – Misuse of Drugs Act 1971
What Happens If You’re Caught With Cannabis
On paper, simple possession carries a maximum of five years in prison, an unlimited fine, or both when prosecuted on indictment.3Legislation.gov.uk. Misuse of Drugs Act 1971 In practice, most people found with a small amount for personal use never see a courtroom.
Scottish police and the Crown Office and Procurator Fiscal Service (COPFS) work from a sliding scale of responses:
- A verbal warning with no formal record, used for borderline situations.
- A Recorded Police Warning (RPW), which is a formal alternative to prosecution. It is not a criminal conviction and stays on Police Scotland systems for two years. The Lord Advocate’s guidelines allow RPWs for simple possession of drugs in any class, cannabis included.4Scottish Police Authority. Recorded Police Warnings5COPFS. Lord Advocate Statement on Diversion from Prosecution
- A fiscal fine, issued by prosecutors without a court hearing.
- Diversion from prosecution, where the prosecutor refers your case to social work or another agency and no further action follows if you complete the programme.
- Full prosecution, kept for repeat offenders, larger quantities, aggravating features such as using cannabis near children, or cases where supply is suspected.
Roughly two-thirds of people reported to COPFS for possession-only offences are dealt with through alternatives to prosecution, and financial penalties make up the bulk of those.5COPFS. Lord Advocate Statement on Diversion from Prosecution A warning is not something you can collect indefinitely. Repeat incidents move you up the scale, and officers weigh factors like whether you were smoking in public or near a school.
These alternatives are reserved for possession. Supply offences face prosecution.
Growing or Sharing Cannabis
Cultivating cannabis or supplying it to someone else is treated far more seriously. The maximum sentence for producing or supplying a Class B drug is 14 years in prison, an unlimited fine, or both.3Legislation.gov.uk. Misuse of Drugs Act 1971 “Supply” is wider than selling. Giving cannabis away or passing a joint to a friend counts.
Cultivation means growing any cannabis plant, at any scale. A single plant on a windowsill and a commercial grow are both illegal. The actual sentence depends on the number of plants, whether there was commercial intent, and whether the case is heard summarily in a sheriff court or on indictment before a jury. A few plants grown at home and a large operation are the same offence in law, even though the outcome in court will look very different.
Driving After Using Cannabis
Scotland has its own drug driving limits. Under the Drug Driving (Specified Limits) (Scotland) Regulations 2019, the legal limit for THC, the psychoactive compound in cannabis, is 2 microgrammes per litre of blood.6Legislation.gov.uk. The Drug Driving (Specified Limits) (Scotland) Regulations 2019 Driving above that limit is a criminal offence under section 5A of the Road Traffic Act 1988. You do not need to appear impaired to be charged. The blood result alone is enough.
If police suspect drug driving, the usual process is a roadside saliva swab that tests for cannabis and cocaine, sometimes alongside a field impairment test checking pupils and balance. A failed roadside test leads to a blood test at the police station, and the blood result determines whether you are charged.7mygov.scot. Illegal Drugs and Driving in Scotland
A conviction brings a driving ban of at least 12 months, 3 to 11 penalty points, a fine of up to £5,000, up to 6 months in prison, and a criminal record. The offence stays on your licence for 11 years. Causing death by drug driving carries a maximum of 14 years in prison.8Road Safety Scotland. Drug-driving
THC can stay detectable in blood long after the high has worn off, especially for regular users, so the 2 µg/L limit can catch people who smoked hours or even a day earlier.
Medical Cannabis Prescriptions
Since November 2018, specialist doctors registered with the General Medical Council have been able to prescribe cannabis-based products for medicinal use, following regulations that moved these products into Schedule 2 of the Misuse of Drugs Regulations.9GOV.UK. Home Office Circular 2018 – Rescheduling of Cannabis-Based Products for Medicinal Use in Humans Only hospital consultants and specialists can prescribe, not GPs.10GOV.UK. Government Announces That Medicinal Cannabis Is Legal
NHS prescriptions remain rare. According to NHS Inform, medicinal cannabis is currently considered for three patient groups:
- Adults and children with severe forms of epilepsy
- Adults experiencing vomiting or nausea caused by chemotherapy
- People with muscle stiffness and spasms caused by multiple sclerosis
Other treatments must have failed or been unsuitable before cannabis is considered.11NHS inform. Medicinal Cannabis Most patients who access medical cannabis in the UK do so through private clinics at significant personal cost. A valid prescription is a legal defence to possession, but you need to be able to prove the prescription if stopped by police.
Are CBD Products Legal
CBD (cannabidiol) products are legal in Scotland, but the rules are tighter than many sellers suggest. Any THC in a finished product is technically a controlled substance under the Misuse of Drugs Act. Home Office guidance sets an exemption threshold of no more than 1mg of a controlled cannabinoid per container, meaning the whole bottle or packet rather than per dose.12GOV.UK. Guidance on Analytical Limits for Controlled Cannabinoids Products must be derived from industrial hemp with naturally low THC levels.
CBD food products carry an extra layer of regulation. Food Standards Scotland classifies CBD extracts as “novel foods” because they have no significant history of consumption in the UK or EU before May 1997. That means CBD food products and supplements require safety evaluation and authorisation before they can legally be sold. As of the most recent Food Standards Scotland guidance, no CBD extract products have been fully authorised, so products currently on sale sit in a regulatory grey area while applications are processed.13Food Standards Scotland. Cannabidiol Business Guidance CBD products also cannot make medicinal claims unless separately licensed as medicines.
Will the Law Change
Scotland has the highest drug-death rate in Europe, which has driven political pressure to rethink policy. In July 2023, the Scottish Government published proposals calling for the decriminalisation of all drugs for personal possession, arguing that people found with drugs should be supported rather than criminalised, and for an overhaul of the drug classification system to reflect actual harm.14Scottish Government. Drug Law Reform Proposals
Because drug law is reserved to Westminster, the Scottish Government cannot act on those proposals alone. Any change needs either the UK Government to amend the Misuse of Drugs Act or further powers to be devolved to Holyrood. In 2025, Glasgow opened the UK’s first safer drug consumption facility, operating under Lord Advocate guidance directing police not to prosecute simple possession within the facility. Outside narrow experiments like that, the law is unchanged and cannabis possession remains a criminal offence across Scotland.
