A neurologist says nitrous oxide is "more dangerous than cocaine" - and some kids are taking 150 canisters a day. The substance - commonly known laughing gas or nos - is one of the most commonly-used drugs among 16-24 year olds in England, the government says.
Dr David Nicholl, consultant neurologist and clinical lead at City Hospital in Birmingham, says he now sees more patients struggling with side effects of 'nos' than cocaine abuse. He said the volume youngsters are taking the substance has rocketed since the pandemic.
Nitrous oxide, which is sold in single-use silver canisters, is dispensed into balloons and inhaled to create a temporary feeling of relaxation and euphoria. Heavy regular use can lead to a range of side effects which include dizziness, weakness in the legs and impaired memory.
