Today we focus on mephedrone, the drug Lincolnshire police have linked with the tragic deaths earlier this week of two teenage boys in Scunthorpe. Reporter Robert Booth recounts what happened to Louis Wainwright, 18, and Nicholas Smith, 19.
We also hear from an (anonymous) man who's used mephedrone. He describes its effects.
Joining our studio panel is Martin Barnes, chief executive of Drugscope, and a member of the Advisory Council on the Misuse of Drugs, which meets on 29 March to discuss a recommendation that mephedrone be banned.
Niamh Eastwood, deputy director of Release, says the sacking of Professor David Nutt from the council led to a delay in the assessment of mephedrone's dangers.
Alan Travis, the Guardian's home affairs editor, explains how the drug is made and the dangers that if it's banned it will simply be replaced by a similar compound.
Reporter Adam Gabbatt looks at how internet users are discussing the drug and its possible prohibition.
