Police said they would “respond appropriately” after a campaign group announced plans to hold a picnic for cannabis users in a Leeds park.
Members of the Leeds Cannabis Social Club were due to gather on Saturday, September 5, at Hyde Park in what they called a peaceful “act of civil disobedience”.
The group is one of several across the country that are campaigning for changes to drug laws.
A spokesman said: “We think that the time police are made to spend dealing with cannabis consumers is a waste of their valuable time and money and a waste of the tax payers money.
“Cannabis consumers would all very much like to have a social space to use so that we can consume cannabis, responsibly, in a well ventilated venue where it will not offend any member of the public”
Insp Howie Milner, of the inner north west neighbourhood policing team, said: “We are aware of the proposed event and will respond appropriately to any offences that occur.”
