Police Warn Of Nitrous Oxide Risks
Police said misuse of nitrous oxide has been linked to serious health risks including oxygen deprivation, nerve damage, heart problems and mental health effects.
Its misuse has also been linked to road deaths.
‘Real Priority’ For Police
Inspector Amanda Holroyd, of Kirklees Police, said the warrant had led to the seizure of significant quantities of nitrous oxide and suspected steroids.

She said illegal drug supply and the violence associated with it remained a major concern for communities.
“The illegal supply of drugs and the associated violent crime it so often brings is a blight on communities and tackling this kind of offending is a real priority for us in Ravensthorpe,” she said.

Inspector Holroyd said police would continue targeting the illegal use and supply of nitrous oxide.
She urged anyone with information about drug crime in Ravensthorpe to contact police or Crimestoppers anonymously.
