My favourite is always Professor David Nutt, fired from his position advising the Home Office for saying ecstasy and LSD were less dangerous than alcohol. https://www.theguardian.com/politics/2009/oct/30/drugs-advis... EDIT: David Nutt on how ecstasy isn't as dangerous as "Equasy" http://www.encod.org/info/EQUASY-A-HARMFUL-ADDICTION.html
I think his idea for 'hangover free alcohol' is pretty interesting as well. http://www.independent.co.uk/life-style/health-and-families/...
Not clear if that's because of cost, regulations, or something else.
