Is CBD oil from a health shop the same as a CBPM?

No. High-street CBD products are food supplements (or, more recently, novel foods) with only trace THC. A CBPM is a prescription medicine that may contain meaningful THC, is dispensed against a specialist prescription, and sits under Schedule 2 of the Misuse of Drugs Regulations. Same plant family; completely different regulatory status.

Are Epidyolex and Sativex CBPMs?

They're cannabis-based medicines, but they're licensed medicines with a marketing authorisation — a narrower category than unlicensed CBPMs. Most private clinics prescribe unlicensed CBPMs (imported specials) because the licensed products only cover a few specific conditions.

Does the source of my CBD matter for a drug test?

Yes. A properly formulated high-street isolate CBD has essentially no THC and won't trigger a workplace test. A full-spectrum CBD product can contain small amounts of THC that build up with regular use and occasionally do trigger tests. A prescribed CBPM containing THC will register on standard tests — that's what makes disclosure and paperwork important.

Why do people say CBD is 'not medicine'?

Because in UK regulatory language a supplement isn't a medicine unless it holds a marketing authorisation. Consumer CBD is sold under food-supplement rules; manufacturers can't legally make medical claims for it. That's a licensing statement about the product, not a claim about whether it does anything for anyone.

Which category am I in, practically speaking?

If a specialist doctor has issued you a private prescription for a cannabis-based product, you're in the CBPM world with all the rights and obligations that carries. If you bought a bottle at Holland & Barrett, you're in the consumer-supplement world. The two worlds sit under different laws, and mixing them up is where patients get into trouble.

CBPM vs CBD: what counts as a cannabis-based medicine in the UK

Prescribed Patient editorial team~7 min readLast reviewed: July 2026

A patient will often say "I take CBD" when they mean a prescribed cannabis oil that contains meaningful THC. An insurer, an employer or a police officer hears that phrase very differently — and the confusion has real consequences. The remedy is to keep the three categories straight.

Category 1: Licensed cannabis medicines

A licensed medicine holds a marketing authorisation from the MHRA. It has been through clinical trials, has an approved indication, is manufactured to consistent specifications, and can be prescribed on the NHS within the terms of its licence.

In the UK, three matter in practice:

Sativex (nabiximols) — an oromucosal spray for MS-related spasticity.
Epidyolex (cannabidiol) — for seizures associated with Dravet, Lennox-Gastaut, and tuberous sclerosis complex.
Nabilone — a synthetic cannabinoid used mainly for chemotherapy-induced nausea.

These are prescription medicines like any other. They carry familiar packaging, an SmPC (summary of product characteristics), and the ordinary machinery of pharmaceutical regulation.

Category 2: Unlicensed CBPMs

This is the category most private-clinic patients are actually in, and it's the one the 2018 law change created.

An unlicensed CBPM is a cannabis-based product for medicinal use in humans that hasn't been through the full marketing-authorisation route. It's prescribed as a "special" — a legal category for unlicensed medicines that a specialist doctor considers clinically necessary for a specific patient. Most whole-plant flower and full-spectrum oil products from UK private clinics fall here.

Legally, unlicensed CBPMs sit under Schedule 2 of the Misuse of Drugs Regulations 2001, following the 2018 amendment. That places them alongside other controlled medicines like morphine — controlled but lawfully prescribable, dispensable and possessable when done properly. Only doctors on the GMC's specialist register can initiate a prescription.

This is the category where the practical rulebook covered elsewhere on this site applies: DVLA fitness-to-drive, workplace testing implications, travel considerations, insurance disclosure. If you have one of these, everything on this site is written for you.

Category 3: Consumer CBD

This is what's sold in health shops, supermarkets and online — oils, capsules, gummies, cosmetics. They're regulated as food supplements, or since 2020 as novel foods under Food Standards Agency rules. Manufacturers can make general wellness claims but not medical claims.

To be sold legally as a consumer product, CBD must be extracted from industrial hemp and contain no more than trace THC. It's not a controlled drug when compliant, doesn't require a prescription, and doesn't sit in either of the categories above.

High-street CBD is not a CBPM. This is the confusion that causes the biggest problems: a patient who says "I take CBD" to their insurer meaning a supplement is telling the truth; a patient who says the same thing to their insurer while actually holding an unlicensed CBPM prescription has misrepresented — even though they think they've disclosed.

Why the distinction changes real-world outcomes

Question	Consumer CBD	CBPM (prescribed)
Legal status	Food supplement / novel food	Schedule 2 controlled medicine
THC content	Trace only	May be meaningful
Prescription required	No	Yes — GMC specialist
Workplace drug test	Not normally triggered	Will register — disclose
Driving THC limit	Not relevant	Medical defence under s.5A(3)
Insurance disclosure	Not normally required	Answer application questions fully

How to describe what you take, precisely

Whenever you're in a formal setting — insurance application, employer disclosure, GP registration, border encounter — use the specific words rather than the generic ones. Not "CBD oil" but "a full-spectrum cannabis-based oil, prescribed under Schedule 2 by a specialist consultant". Not "I use cannabis for pain" but "I take a prescribed cannabis-based medicinal product for [condition]". The precision costs nothing and it heads off the exact misunderstandings that cause disputes.
