How UK medical cannabis delivery works (and why delays sometimes happen) in 2026

Why your medical cannabis delivery must be handled with extra care

The regulations put in place by the UK government are not casual guidelines. They are strictly overseen safeguards designed to protect the integrity of your medication at every stage of its journey, from pharmacy to front door.

What does that actually look like, though?

In practical terms, it means tighter storage controls, detailed tracking, and clear accountability at every handover point. When your prescription is dispensed, it is logged. When it leaves the pharmacy, it is recorded. When it is transferred into a licensed courier network, it remains traceable. And when it reaches you, identity verification is required before it can be handed over.

And while this may seem somewhat excessive at first, it is deliberate and totally necessary. 

Not only does it reduce the risk of loss, tampering, or damage to your medication, but it also makes sure that only you can access the medication you have been prescribed. That means no Releaf deliveries left tucked behind a plant pot or hidden behind a bin. Your medication must be handed directly to you, with identity verification at the door.

And because those safeguards continue in transit, your prescription can only be transported by properly licensed couriers.

Why all Releaf deliveries must use licensed specialist couriers

Only certain couriers hold the correct licences to legally transport controlled medicines. Because your prescription must remain within a compliant pharmaceutical chain at all times, it can only be handled by courier companies that hold the appropriate licences and meet strict regulatory standards.

Our courier partner, DPD, holds all of the required pharmaceutical handling licences and is currently the only licensed national courier in the UK able to manage the volume of deliveries we send each day. 

DPD deliveries are also secured with PIN verification when the parcel is handed to you. On the day of delivery, you will receive a text or email confirming your 1-hour delivery window, along with a unique PIN code that must be provided before your medication can be released to you. 

Why Releaf does not use Royal Mail for most deliveries

In short, to make sure that all deliveries are delivered in the quickest time possible.

While Royal Mail can legally deliver medical cannabis prescriptions, our deliveries must remain within a specialist controlled-drug handling process from dispatch to successful handover. If a delivery attempt is unsuccessful, the medication cannot be treated like a standard undelivered parcel and left unattended.

DPD operates within a licensed pharmaceutical handling framework and can legally hold controlled medicine deliveries within its network for up to 72 hours while attempting redelivery. If delivery is still unsuccessful after that period, the prescription must be returned to the pharmacy for reprocessing.

Royal Mail does not operate within the same compliant holding-and-returns framework for medical cannabis prescription deliveries. In certain circumstances, this means the medication may not be safely returned to the pharmacy and may need to be destroyed instead.

This, in turn, can lead to long delays, with the entire order then needing to be reprocessed. 

That said, for patients in the Scottish Highlands or Northern Ireland, delivery is handled by Royal Mail due to regional logistics requirements, as DPD does not provide the same delivery coverage in those areas. In those cases, prescriptions follow Royal Mail’s standard delivery process.

What happens between your prescription being approved and arriving at your door

Once your prescription has been approved and payment has been confirmed, it moves through a regulated and structured process to make sure everything is kept fully legal and compliant. 

Why can delivery occasionally take longer than 2 to 5 days?

The most common reason for an extended delivery timeline past our 2 to 5 day target is a missed delivery attempt. As we mentioned above, because your delivery is a controlled medication, it cannot legally be left unattended or redirected in the same ways as a standard parcel delivery.

DPD can legally hold Releaf prescription deliveries within its internal network for a maximum of 72 hours, and they will try to deliver your medication each day that they have custody of the parcel. But if they are unable to successfully deliver your prescription within this time frame, it legally must be returned to the pharmacy. 

Once the pharmacy has hold of the returned prescription, they are required to reprocess the order and complete further checks to confirm the medication has not been tampered with before it can be reissued. That additional step can add time, but it protects the integrity of your treatment.

We understand that receiving a delivery during working hours can sometimes be difficult to coordinate. That's why, starting soon, we will be introducing Saturday and Sunday delivery options to help reduce disruption and make planning easier.

How Releaf works to ensure your medical cannabis delivery arrives as quickly as possible

As the most trusted medical cannabis clinic in the UK, we take responsibility for every stage of your prescription journey extremely seriously.

From clinician approval to pharmacy dispensing and secure courier handover, each step is meticulously coordinated to minimise delays while always maintaining full regulatory compliance. 

Releaf patients were the first in the UK to receive domestically grown medical cannabis strains thanks to our ongoing partnership with Glass Pharms®. Alongside UK cultivation, we work exclusively with the most reputable UK and international suppliers to ensure consistent quality, reliability, and continuity of access for our patients.

We acknowledge that not every single patient always receives their Releaf delivery within 5 days, but with that said, certain elements of medical cannabis delivery are governed by strict regulatory frameworks that sit outside our direct control. We will always do everything in our power to make sure that your prescription delivery moves forward as quickly and as safely as possible, while abiding by the regulatory requirements set out by the UK government.
