Should the legal high Poppers be banned? Angela Epstein and MP Mike Freer clash

A senior Conservative MP has revealed in the House of Commons that he uses the legal party drug, poppers. Crispin Blunt, who's the chairman of the Foreign Affairs Select Committee, was arguing against government plans for a blanket ban on so-called legal highs.
MPs have now voted to include poppers on the list of substances which could be banned, but was it ok for Mr Blunt to defend a legal high that he admits he likes using?
