Professor Colin Blakemore Member, UK Drug Policy Commission; former director, Medical Research Council

* Dr Leslie King Member, ACMD
* Ruth Runciman Former member, ACMD
* Prof Ian Gilmore, President, Royal College of Physicians and member, Academy of Medical Sciences Working Group on Brain Science, Addiction and Drugs

I'm slightly miffed El Reg's resident computer-scientist-cum-global-warming expert isn't on the list - perhaps he has an opinion on this topic too?
