Jersey, a Tiny Island, Has Become a Hub for Medical Cannabis in Europe
Jersey, a British Crown Dependency of about 100,000 people, has emerged as a notable medical cannabis exporter. Producer Northern Leaf shipped £8.4 million of product in 2025, though the industry is drawing controversy on the island.
Jersey, the largest of the Channel Islands between England and France, has become an unlikely player in the medical cannabis industry. The island is a British Crown Dependency that makes its own laws. It covers about 45 square miles and has roughly 100,000 residents. Medical cannabis was legalized there in 2019, and the sector is now seen as an important new part of the local economy.
The main producer
About 90 percent of the island's cannabis output comes from Northern Leaf, which operates in St Lawrence. Its 100,000-square-foot greenhouse once grew tomatoes and is now equipped with automated irrigation, environmental monitoring and air purification. Jersey's total exports exceeded 9,200 kilograms in 2025. Northern Leaf alone exported £8.4 million ($11.3 million) of product last year, mainly to the UK and Germany. Rules allow it to grow only for export.
Chief executive Steven Tan, who took over in 2024 when the company was struggling after a failed IPO, says capacity use has risen from 25 to 75 percent. Jersey's chief minister, Lyndon Farnham, wants the island to become a centre of excellence for medical cannabis.
Opportunities and objections
Barrister Sarah Clover points to inspections by the UK medicines regulator, the MHRA, and fast permit approvals as the island's advantages. Industry figures also want to package finished products locally, but current law allows only bulk exports of raw cannabis.
Some residents complain about the smell. According to the island's health minister, cannabis is a contributory factor in 22 percent of admissions to the acute mental health ward. Police warn that illegal resale of medical cannabis undermines the legal framework. At the same time, cannabis-related offenses fell from 216 in 2016 to 12 as of July 2026.
A loophole for recreational sales
In 2024, a vote in Jersey's parliament to decriminalize recreational cannabis failed by a single vote, and the issue is expected to return. Meanwhile, Gary Tucker, who runs the shop Bailiwick Botanicals, exploits a legal loophole: the law caps THC in CBD products at 3 percent of the CBD's weight, so raising the CBD level allows higher THC content.
