The ‘hash brownies’ responsible for the hospitalizations were bought from Christiania, an alternative enclave within Copenhagen which has an illicit hash trade and is subject to frequent police clampdowns.
Copenhagen’s Rigshospital has treated seven people within the last four weeks with symptoms including low heart rates, unconsciousness and psychosis-like states, broadcaster DR reports.
All seven had eaten a hash brownie – a cake in which cannabis is an ingredient – purchased for 50 kroner in Christiania, the broadcaster writes.
Additional people may have been affected, but the emergency ward at Rigshospital only recently made the connection between symptoms and source, according to the report.
The seven patients were seriously – possible life-threateningly – ill after eating the cakes, which affected their heart rates and circulation, according to Rigshospital.
A Danish citizen along with tourists from Ireland, Germany, the United States, Finland, Spain and Japan were affected, the hospital confirmed to DR. All patients were discharged after two days.
Copenhagen Police said it had confiscated 4,000 hash cakes in 2019. The general figure does not solely refer to items confiscated in Christiania.
Simon Hansen, an inspector with the police special operations unit in the city, reiterated that it is illegal to buy hash products at Christiania and added that police would begin warning about potential acute health hazards.
“Based on what we have recently been told by Rigshospital, we will be advising people that the hash cakes currently may be very dangerous,” Hansen told DR.
“But whether there’s anything unusual in these cakes, we can’t say at this time,” he added.
A police action on Wednesday resulted in 58 people being apprehended for being in possession of cannabis. Recently-confiscated hash cakes are to undergo testing for drugs other than cannabis, DR reports.
