What are the dangers of using nitrous oxide - the laughing gas drug?

Nitrous oxide, which is also known as laughing gas, is sold in metal canisters and is one of the most commonly used drugs by teenagers and young people. However, heavy use can lead to a host of problems. Prof Alastair Noyce, a consultant neurologist at Queen Mary University of London, told BBC News: "These are young people we are seeing - teenagers and people in their 20s.
