W. B. O'Shaughnessy — On the Preparations of the Indian Hemp, or Gunjah (Provincial Medical Journal, 1843) 1 unchanged

Cannabis is a Class B drug: possession carries up to five years in prison and an unlimited fine.[@sa] In practice police in England and Wales use an escalation — a cannabis warning or community resolution first, a £90 penalty notice next, then arrest.[@sa] Of those who do reach court, about 60% are fined and 20% conditionally discharged; immediate custody is uncommon and usually a month or less.[@sa] [The government rejected decriminalisation in 2026.](/history/uk-commission-recommendations-rejected-2026/) [London police piloted cannabis warnings in 2001.](/history/uk-lambeth-cannabis-warning-pilot-2001/)

label Possession of a Class B drug · term Possession of a controlled drug · treatment criminal · prison 5 years · note Unlimited fine and/or up to five years; out-of-court disposals usual first

Growing any number of plants is production of a controlled drug, with up to 14 years on indictment.[@sa,boc] A few plants for personal use typically bring a fine or community order.[@sa] [The government rejected decriminalisation in 2026.](/history/uk-commission-recommendations-rejected-2026/)

label Production of a Class B drug · term Production of a controlled drug · treatment criminal · prison 14 years · note Unlimited fine and/or up to 14 years on indictment

Mostly out-of-court disposals and fines for users, with wide variation between police forces.[@sa] Production and supply are imprisonable and enforced.[@sa]

label Supply of a Class B drug (including giving to a friend) · term Supply of a controlled drug · treatment criminal · prison 14 years · note Unlimited fine and/or up to 14 years

Use is prosecuted through the possession offence.[@sa] Letting your premises be used for smoking cannabis is a separate offence.[@sa,boc] [The government rejected decriminalisation in 2026.](/history/uk-commission-recommendations-rejected-2026/)

No legal adult-use source. Since November 2018 specialist doctors can prescribe cannabis; … clinics, which now serve tens of thousands of patients with flower delivered by pharmacy.[@pp,bmj] [Specialists could prescribe cannabis from November 2018.](/history/uk-medical-cannabis-2018/)

There is no legal way to buy cannabis for adult use: all of it is supplied illegally, most … the government answered in 2026 that it has no plans to change the law.[@londondc,parl26] [The government rejected decriminalisation in 2026.](/history/uk-commission-recommendations-rejected-2026/)

The Home Office licenses cultivation, mainly for pharmaceutical products and export, plus low-THC hemp.[@boc] The UK is a large exporter of cannabis-based medicines.[@pp] [GW Pharmaceuticals won a cultivation licence in 1998.](/history/uk-gw-pharmaceuticals-licence-1998/)

Legal since 1 November 2018, but only doctors on the specialist register may initiate it, and the NHS funds it for a handful of patients.[@pp] In November 2019 the medicines watchdog NICE approved two cannabis-based medicines, for two forms of epilepsy and for multiple sclerosis, and declined to recommend them for other conditions such as chronic pain.[@bmj] The private route costs patients a consultation fee plus the product.[@bmj,pp,cgh] Prescription products include flower, oils and vape cartridges through clinics.[@pp] [British doctors took up Indian hemp as a medicine in 1843.](/history/uk-doctors-take-up-indian-hemp-1843/) [Specialists could prescribe cannabis from November 2018.](/history/uk-medical-cannabis-2018/)

A caution or conviction shows on criminal-record checks and can affect work and travel; a cannabis warning is recorded but not shown on a standard check.[@sa] Drug-driving has a very low THC limit.[@sa,boc]

The Misuse of Drugs Act's definition of cannabis leaves out the seed, so buying and holding seeds is not an offence.[@mda] Cultivating any plant of the genus Cannabis is unlawful without a licence, which covers germinating seeds and keeping cuttings, so cuttings cannot lawfully be sold.[@mda]

All recreational cannabis is supplied illegally.[@iea18] The most detailed estimate found is old: a 2018 report by the Institute of Economic Affair … n pounds at ten pounds a gram, and described a market dominated by high-strength cannabis.[@iea18] No recent official estimate was found.

No law provides for clubs and cannabis remains a class B drug.[@td24] A federation, UK Cannabis Social Clubs, was founded in 2011 and by 2016 counted more than 80 clubs, most with 100 to 150 members and registered as non-profits.[@td24] Most have since gone: there were still dozens in 2019, but the pandemic, unpaid rents, infighting and arrests broke the movement, and one organiser was jailed for running a cannabis café.[@td24] Teesside Cannabis Social Club in Stockton-on-Tees is one of the few survivors and the only … £120 a year, and cannabis grown mostly by about a dozen members was sold on the premises.[@td24] Newer venues are opening as lounges for holders of private medical prescriptions, some with the apparent blessing of local police.[@wikitcc] Tolerance is a matter of local police discretion, not national policy.[@td24,volteface16,wikitcc]

The THC limit is 2 micrograms per litre of whole blood in England and Wales and, since 21 October 2019, Scotland.[@govdd,scot_driving,govlim] Exceeding the limit can be an offence without proof of impaired driving.[@govdd] A roadside saliva screen for cannabis is followed by evidential testing; a positive screen alone is not the measured blood concentration.[@govdd] Patients taking a lawfully supplied medicine as instructed can raise a medical defence to the specified-limit offence, but not to driving while impaired.[@drug_medical] GOV.UK lists a minimum one-year driving ban, an unlimited fine and up to six months in prison, with the conviction recorded on the licence for eleven years.[@govdd] Northern Ireland instead prosecutes driving while unfit through drugs, with a minimum one-year ban and a fine of up to £5,000; these Great Britain blood limits do not apply there.[@ni_driving]

There is no legal recreational supply for anyone, so a visitor has no lawful way to buy cannabis.[@pp] Whatever legal supply exists is medical, for patients with a prescription or registration.[@bmj] The sources behind this profile describe no separate rule for visitors.

Home Office statistics for England and Wales count 269,321 drug seizures by police forces … s was present in 72 per cent of them: 194,682 seizures, up 28 per cent on the year before.[@ho_seizures25] Most police seizures are small. Of herbal cannabis seizures, 12 per cent weighed under one gram and 54 per cent between one gram and 500 g, and three quarters of plant seizures involved ten plants or fewer.[@ho_seizures25] Police recorded 204,664 drug offences in the same year, up 12 per cent; the Home Office notes that each seizure also generates a recorded offence, so the two series move together.[@ho_seizures25] The figures do not cover Scotland or Northern Ireland.[@ho_seizures25]

CBD foods have a separate approval process. The FSA’s [board paper updated on 19 October 2 … dations-2026/) sought agreement on recommendations for three high-purity CBD applications,[@cbd2026] with proposed adult-only conditions and a 10 mg daily maximum.[@cbd2026] Final authorisation decisions belong to ministers in England and Wales, with Northern Ireland’s health minister informed; this paper records recommendations.[@cbd2026]

Britain met cannabis twice, a century apart. In 1839 [William O'Shaughnessy](/culture/people/william-oshaughnessy/), an Irish doctor in Calcutta, published his trials of Indian hemp on animals, himself and patients; within a few years British doctors were prescribing its tincture, and a medical journal gave its 1843 front pages to his findings.[@oshaughnessy] In 1969 [Baroness Wootton's](/culture/people/barbara-wootton/) committee told the Home Secretary that moderate use did no lasting harm and prison was the wrong answer for small possession — and was rejected, though the 1973 Act that followed halved the possession maximum from ten years to five.[@wootton] The older folk custom survives in verse: on Halloween, Scots girls sowed hemp seed to dream of their husbands, as Burns recorded.[@halloween] [British doctors took up Indian hemp as a medicine in 1843.](/history/uk-doctors-take-up-indian-hemp-1843/) [The Wootton report found moderate use harmless in 1969.](/history/uk-wootton-report-1969/) [Cannabis possession stayed criminal under the 1973 Act.](/history/uk-misuse-of-drugs-act-1973/)
