Medical cannabis in Swansea

Almost everything about medical cannabis is decided nationally. This page covers the parts that genuinely differ for someone in Swansea -- who commissions NHS care here, and which police force you would be explaining a prescription to -- and is honest that the rest does not.

Is medical cannabis legal in Swansea?

Yes. Cannabis-based products for medicinal use have been lawful on a specialist prescription throughout the UK since 1 November 2018, and Swansea is no exception -- there is no local variation in this.

The Misuse of Drugs Regulations 2001 were amended in 2018 to move cannabis-based products for medicinal use into Schedule 2. That was a UK-wide change made at Westminster, and drugs policy is not devolved, so the same rule applies in every nation of the UK.

What it did not do is make cannabis legal, or create a local scheme in Swansea that you can apply to. It created one narrow route: a doctor on the GMC specialist register decides, for a named patient, that a cannabis-based product is appropriate. Everything else about cannabis remains a criminal offence, and holding a prescription does not change that for anything you did not obtain on it.

So the honest answer to the question people in Swansea actually mean -- can I get this -- is that legality is not the obstacle. The obstacle is whether a specialist concludes that your condition meets the threshold, which is a clinical judgement and not a formality.

NHS care in Swansea

The route runs through Swansea Bay University Health Board rather than an English integrated care board, and the same national constraint applies: NHS prescribing of unlicensed cannabis-based medicines in Wales is rare.

Health in Wales is devolved, so Swansea Bay University Health Board commissions specialist services for Swansea and the All Wales Medicines Strategy Group advises on new medicines rather than NICE doing it directly. The 2018 rescheduling itself was UK-wide, so what you may lawfully be prescribed does not change at the border.

A specialist in a Welsh health board can prescribe on the same terms as one in England. What is different is the funding pathway behind them, and the fact that a cross-border referral to an English centre needs agreement from the health board first.

In practice the great majority of people in Swansea with a prescription hold a private one, for the same reason as in England: the evidence base has not moved far enough for routine NHS funding.

What is actually different about Swansea

Two things: who would fund NHS care, and which police force you would meet at a roadside stop. Little else.

NHS commissioning for Swansea sits with Swansea Bay University Health Board. That determines the funding route and the referral pathway to a specialist, and in wales it also determines which national body advises on medicines.

Roads in Swansea are policed by South Wales Police. The drug-driving law is national, but the force you would be showing a pharmacy label to is local, and that is worth knowing.

Beyond those two, claims of local advantage in this sector should be treated sceptically. The law, the guidance, the specialist register and the evidence base are all national, and nothing about living in South Wales makes a prescription more or less likely.

Who is allowed to prescribe

Only a consultant on the GMC specialist register. No GP in Swansea can start a cannabis-based medicine, however supportive they are, and that is a matter of law rather than local policy.

This is the central control in the 2018 regulations and the thing most often misunderstood. The specialist register is not a seniority badge: it means the prescriber completed specialist training and is listed on a public register that anyone can search before booking anything.

The specialty that matters depends on the condition. Pain medicine, neurology, psychiatry, gastroenterology, rheumatology and palliative medicine each cover part of the list below, and a specialist will normally only assess within their own field.

• A confirmed diagnosis from your records, not a self-assessment
• Evidence that licensed treatments were tried and did not work or could not be tolerated
• Your history, including any personal or family history of psychosis, which is the most important contraindication here
• Everything else you take, because interactions are real
• Whether you drive, and what you do for work

Your GP record does more work than anything you say in the appointment. A specialist who cannot see a documented history generally cannot prescribe, because the unlicensed route requires them to evidence why licensed options were not enough. Getting your summary care record from your practice in Swansea is therefore the single most useful thing to do before booking.

The evidence is not the same for every condition

Lumping these together would be misleading. Three of the 27 have a licensed product or a positive NICE recommendation; one is a condition NICE recommends against treating this way; the other 23 rest on limited evidence.

Anyone reading a page like this deserves to know which group their condition is in before they spend money on a consultation, so it is set out here rather than buried.

• A licensed route exists for multiple sclerosis, epilepsy, nausea and appetite loss — these are narrow, specific indications rather than the whole condition
• NICE recommends against prescribing for chronic pain outside a clinical trial, and that is national guidance no specialist can set aside locally
• The remaining conditions have limited evidence: benefit is widely reported in uncontrolled settings and has generally not been confirmed in controlled trials

None of that varies by address. A specialist assessing someone in Swansea works from the same literature and the same guidance as one assessing someone four hundred miles away, which is why this page spends more time on evidence than on geography.

Driving and police in Swansea

A prescription gives you a statutory defence, not an exemption. It is South Wales Police you would be explaining that to, and it is still an offence to drive while impaired.

Section 5A of the Road Traffic Act 1988 sets a near-zero limit for THC. A prescription provides a medical defence to that specific charge, provided the medicine was taken in accordance with the directions you were given.

That defence does nothing for the separate offence of driving while unfit through drugs, under section 4. If an officer from South Wales Police judges that your driving is impaired, the prescription is irrelevant to that charge. Anyone taking a cannabis-based medicine should assume that impairment is possible, particularly after a dose change.

• Carry the medicine in its pharmacy-labelled container
• Keep a copy of the prescription or the clinic's letter with you
• Do not drive after a dose increase until you know how it affects you
• Expect a roadside swab to be positive -- the defence operates after that point, not instead of it

Being stopped is not an accusation of anything. South Wales Police officers encounter prescribed controlled drugs routinely, and a labelled pack with a prescription is a normal and sufficient explanation.
