Medical cannabis — overview

The UK’s estimated medical market size for 2025 is over €300 million.

The pace of regulatory growth in medical cannabis has been slow in the UK, however the rate of market development has been rapid. Patient numbers are rising significantly each year, alongside a growth in suppliers, clinics and pharmacies.

The UK’s market is open to new players and new suppliers, however it is a strictly regulated environment, with import licensing procedures in particular posing an obstacle to suppliers. Participation in the market requires strong relationships with the network of players operating in the industry.

The majority of market supply is through imports, although due to the nature of the UK’s regulatory frameworks, a large proportion of imports are of products which are legally classified as raw materials, with final manufacturing steps carried out domestically. As well as this, commercial domestic cultivation has been rising rapidly over the past year. Several UK players are now selling significant volumes of UK-cultivated flower in the market, and several more are gearing up to do the same.
