I thank the hon. Member for securing this really important debate and for making such a significant and poignant speech. I find it very distressing to know that young people are able to access these silver cylinders and that they have such a harmful effect on them. In my constituency, I have seen pockets of those cylinders in various places, and I am pleased that he has brought the matter to the Government’s attention. Does he agree with me that we need more work to be done on health and education as well as on enforcement to make sure young people are not able to purchase them?
