Dangerous Drugs

I am grateful to my right hon. Friend for mentioning that Westminster Hall debate. Does he agree that campaigners such as Dr David Nicholl, an eminent neurosurgeon in Bromsgrove, were also instrumental? He was responsible for raising with me and many colleagues the unbelievable harm that this does to children, who think that, because it is called laughing gas, it is amusing, but it actually causes profound neurological problems for those who use it too much.
