Black Market Cannabis in Jersey

Contraband Cannabis

Historically, the black market for cannabis in Jersey primarily consisted of hashish (cannabis resin) imported from Morocco via France or the UK. Herbal cannabis was generally relatively rare in the Island, with some instances of personal cultivation and purchases from the dark web.

Up until the late-2000s, the majority of the hash available in the Island was of low quality and often contaminated. Known as 'soap bar' due to the appearance of the standard 250g (9oz) blocks of resin, this was sold on the black market at a price of £160 per ounce (£5.71/g) from at least the late-1980s.

Around 2010 the Island's black market for cannabis changed, offering a higher grade of hashish at an increased price. Initially sold for £10 per gram (from 100g blocks), this increased over the years to upwards of £15 per gram prior to the coronavirus pandemic.

While cannabis seizures by Police and Customs have at times had an impact upon the supply of cannabis to the black market, availability did not appear to have been problematic for the community until 2020.

The limits on travel imposed as a consequence of COVID-19 dramatically reduced the availability of hashish on Jersey's black market, leading to an increase in prosecutions for postal importation and personal cultivation. This reduction in supply led to an increase in the street price of cannabis in the Island to upwards of £25 per gram.

Prices have since reduced but remain higher than before the pandemic at around £20 per gram.

The availability of medicinal cannabis in Jersey since 2020 has had a dramatic impact on the black market by providing a legal route of supply for those eligible for a prescription. There are however reports of medicinal cannabis being diverted to the black market as a consequence of the recent lack of illicit supply.

Cannabis Use in Jersey

Given that figures pertaining to the overall number of cannabis users in Jersey are unavailable, we must rely on statistics of the prevalence of cannabis use in Western European countries to provide an estimate. On that basis, it is reasonable to suggest that approximately 5% of the adult population (~5,000 people) have consumed cannabis in a normal year.
