The conflict involving Iran has created disruption across international energy markets and important shipping routes during 2026. Commercial traffic through the Strait of Hormuz has been affected, while fuel prices, maritime insurance costs and wider supply-chain risks have increased.

The Strait of Hormuz is particularly important because it connects major Gulf oil and gas producers with global markets. Disruption in this region can influence energy, transport, fertiliser, packaging and manufacturing costs far beyond the Middle East.

There is currently limited evidence showing that the conflict has caused widespread shortages of cannabis or legal cannabinoid products in the UK. However, the industry could still experience indirect pressure through higher energy costs, delayed imports and more expensive production materials.

This article explains the potential effects on the regulated medical cannabis sector, hemp-derived cannabinoid businesses and UK consumers.

What Happened in 2026?

Large-scale military escalation involving Iran began at the end of February 2026. The conflict subsequently affected commercial shipping in and around the Strait of Hormuz.

The UK Government and international partners expressed concern about attacks, mines and restrictions affecting commercial vessels. Efforts have continued to protect freedom of navigation and restore reliable shipping through the region.

Although periods of reduced military activity and diplomatic engagement have occurred, the situation remained uncertain at the time of this review.

Why Is the Strait of Hormuz Important?

The Strait of Hormuz is a narrow maritime passage linking the Persian Gulf with the Gulf of Oman and international shipping routes.

It is particularly significant for the transportation of:

Crude oil.
Liquefied natural gas.
Petroleum products.
Fertilisers.
Industrial chemicals.

When vessels are delayed, redirected or required to operate under increased security, shipping costs can rise throughout the wider global economy.

How Could the Conflict Affect the Cannabis Industry?

The UK cannabis and cannabinoid sectors do not depend exclusively on products moving through the Strait of Hormuz. Nevertheless, businesses remain connected to global energy, agricultural and manufacturing markets.

Potential indirect effects include:

Higher electricity and heating costs.
More expensive fertilisers and growing inputs.
Increased packaging costs.
Higher international freight charges.
Greater maritime insurance costs.
Longer lead times for specialist equipment.

The extent of any effect will vary considerably between cultivators, manufacturers, pharmacies and consumer-product retailers.

Energy Costs and Indoor Cultivation

Indoor cannabis cultivation can require substantial amounts of electricity for lighting, ventilation, humidity control and temperature management.

If instability in the Gulf contributes to higher wholesale energy prices, cultivators may face increased operating costs.

This does not automatically mean that retail prices will rise immediately. Producers may absorb costs temporarily, use fixed energy contracts or improve efficiency. However, prolonged energy-market disruption can eventually influence wholesale pricing.

Fertilisers and Agricultural Inputs

Cultivation businesses rely on fertilisers, growing media, pest-control products and other specialist agricultural inputs.

Natural gas and petroleum products are important to parts of the global fertiliser and chemical industries. Disruption to energy supplies or shipping routes can therefore affect agricultural input prices even where the final crop is grown in Europe, Canada or the UK.

Businesses using several suppliers or maintaining appropriate stock reserves may be better positioned to manage short-term disruption.

Packaging and Manufacturing Costs

Cannabinoid products commonly require packaging such as:

Glass containers.
Plastic tubs.
Sealed pouches.
Labels.
Protective postal materials.
Laboratory and manufacturing equipment.

Many of these items depend on energy-intensive manufacturing or international transportation.

Higher fuel and shipping costs can therefore influence packaging prices even when the cannabinoid ingredients themselves are sourced from unaffected regions.

The UK Medical Cannabis Supply Chain

The UK medical cannabis market relies substantially on imported products. Licensed medicines may originate from countries including Canada and European jurisdictions before being supplied through authorised UK pharmacies.

Medical cannabis imports are tightly controlled and operate through regulated pharmaceutical supply chains.

Potential disruption could arise from:

International freight delays.
Changes to air-cargo capacity.
Longer customs or import-processing times.
Increased transport costs.
Short-term pressure on particular prescribed products.

However, a shortage of one medicine or cultivar does not necessarily indicate that the entire UK medical cannabis market has been disrupted.

Could Medical Cannabis Patients Experience Delays?

Some prescribed products may be more vulnerable than others depending on their country of origin, available stock and the resilience of the relevant supply chain.

Patients should not change treatment, ration medication or seek unregulated alternatives without speaking to their prescribing clinic or pharmacy.

Anyone concerned about the availability of a prescribed cannabis-based medicine should contact the healthcare provider responsible for that prescription.

What About Legal Hemp-Derived Cannabinoid Products?

The consumer cannabinoid market is separate from the prescription medical cannabis sector.

Depending on their composition and regulatory status, UK retailers may offer hemp-derived products containing cannabinoids such as CBD and CBG.

Potential supply-chain pressure may affect:

Imported cannabinoid ingredients.
Laboratory testing costs.
Packaging materials.
Manufacturing equipment.
International and domestic transport.

These pressures may vary by business. Retailers sourcing from Europe or holding stock within the UK may experience different effects from companies relying on frequent long-distance imports.

Will UK Cannabinoid Prices Rise?

It is not possible to state that the Iran conflict will cause a specific price increase across the entire UK market.

Prices are influenced by numerous factors, including:

Energy costs.
Raw-material availability.
Exchange rates.
Shipping charges.
Supplier contracts.
Domestic demand.
Regulatory and laboratory costs.

If elevated energy and freight costs continue for a prolonged period, some businesses may eventually adjust their prices. Others may reduce margins, change suppliers or absorb short-term increases.

Could Product Shortages Occur?

Temporary shortages are possible within any import-dependent industry, but there was no clear evidence at the time of review that the conflict had caused a general shortage of legal cannabinoid products throughout the UK.

Availability may still vary between individual products because of:

Supplier delays.
Manufacturing interruptions.
Unusually high demand.
Regulatory checks.
Transport disruption.
Routine stock changes.

Consumers should avoid treating isolated stock shortages as proof of a nationwide market crisis.

Could UK Delivery Times Be Affected?

International freight may be affected where products or materials travel through disrupted routes. However, once stock is held within the UK, domestic parcel delivery is governed mainly by the performance of the selected British carrier.

Royal Mail delivery times are therefore more likely to be affected by UK weather, local staffing, operational backlogs or domestic transport problems than by the Strait of Hormuz directly.

Buying Cannabis Online in the UK: Understanding the Law

Global conflict does not change the legal status of recreational cannabis in the United Kingdom.

There is no legal online recreational cannabis market in the UK. Cannabis containing controlled amounts of THC remains subject to the Misuse of Drugs Act 1971 unless a specific exemption applies.

Legal routes and product categories include:

Cannabis-based medicinal products prescribed by specialist clinicians.
Hemp-derived cannabinoid products that comply with applicable UK requirements.

Consumers should not assume that an overseas website is legal simply because it advertises international delivery.

War-Related Cannabis Scams

Fraudsters may exploit international disruption by claiming that an additional payment is required because of the conflict.

Possible excuses include:

Emergency shipping fees.
War-risk insurance.
Customs surcharges.
Alternative-route charges.
Parcel-release payments.
Security deposits.

Unexpected charges introduced after an order has been paid for should be treated with caution and verified independently.

An illegal seller may use genuine news about shipping disruption to make a fabricated payment demand appear credible.

Our Cannabis Scams UK guide explains how fake courier and insurance scams typically operate.

How Businesses Can Improve Supply-Chain Resilience

Cannabinoid businesses can reduce their exposure to international disruption by:

Working with more than one approved supplier.
Maintaining appropriate stock levels.
Sourcing packaging from several regions.
Reviewing transport and insurance arrangements.
Monitoring energy and exchange-rate movements.
Communicating honestly about genuine delays.
Maintaining batch traceability when suppliers change.

Businesses should not reduce laboratory testing or compliance controls simply because costs have increased.

Why Laboratory Testing Remains Essential

Supply disruption may encourage some businesses to seek alternative ingredients or manufacturers.

Any change of supplier should be supported by appropriate due diligence and product testing.

Depending on the product, testing may include:

Cannabinoid composition.
Controlled cannabinoid content.
Heavy metals.
Pesticides.
Residual solvents.
Microbiological contamination.

What Should Consumers Do?

Consumers do not need to panic or purchase unusually large quantities because of speculative reports about future shortages.

A sensible approach includes:

Checking whether a product is actually in stock.
Reviewing published dispatch information.
Allowing extra time for genuinely imported items.
Avoiding unverified sellers claiming exclusive emergency stock.
Questioning unexpected post-payment charges.
Using established customer-support channels.

Patients relying on prescribed medicines should contact their clinic or pharmacy rather than attempting to replace a delayed medicine with an unregulated product.

International shipments may face delays, but domestic Royal Mail delivery is more directly influenced by UK operational conditions once a product is already held in the country.

Is it legal to order recreational cannabis online in the UK?

No regulated recreational online cannabis market currently exists in the UK. Cannabis remains controlled unless supplied under a specific lawful exemption.

Can I order medical cannabis online?

Prescribed cannabis-based medicinal products may be supplied through authorised pharmacies following assessment and prescription by an appropriately qualified specialist clinician.

Are emergency war-risk courier fees genuine?

Unexpected fees should be independently verified. Fraudsters may use phrases such as war-risk insurance or emergency customs clearance to obtain additional payments.

Should I stockpile cannabinoid products?

There is no evidence supporting panic purchasing. Consumers should make proportionate decisions based on genuine availability and their normal requirements.

Could locally produced products be less affected?

Domestic production may reduce exposure to some international shipping delays, although UK manufacturers can still depend on imported energy, equipment, ingredients and packaging.

Final Thoughts

The 2026 Iran conflict has affected global shipping and energy markets, particularly around the Strait of Hormuz. These developments could indirectly influence parts of the cannabis and cannabinoid industry through higher cultivation, manufacturing, packaging and freight costs.

However, claims of widespread UK cannabis shortages or guaranteed price increases should be treated cautiously unless supported by reliable evidence.

The effects will differ between prescription medicines, imported ingredients, UK-held stock and domestically distributed products.

Consumers should remain informed, avoid panic purchasing and be alert to sellers using the conflict as an excuse for unexpected courier or insurance payments.
