Laughing gas or nitrous oxide, as it is also known, is becoming the cigarette butt of our time. I am sure Members across the House are seeing an increasing number of those toxic silver cannisters piling up across their neighbourhoods, as in Bolton. This is a scourge on our society and no parent wants their child exposed to that sea of silver. Does my right hon. Friend agree that we are in need of a new debate on how to put an end to what is no laughing matter?
