I am really interested in the hon. Member’s speech and in the harms from nitrous oxide that he raises. As somebody whose lung was punctured as a result of using nitrous oxide during childbirth, I am keen for what he says about education to be at the heart of the proposals that he is making so that we tell people about the very real dangers they face if they misuse nitrous oxide. The only reason I came through it safely was because I was using it in a medical setting with medical professionals who could look after me.
