Proffessor David Nutt
Not sure if anyone has heard of him. He has some great lectures on you tube about the dangerous of alcohol as a drug, how its the most harmful drug, and the government turning a blind eye to it. He actually spoke out about the dangers of alcohol compared to drugs and funnily enough, swiftly got sacked. Guess it hurt too many peoples pockets for the information to get out too publically. Anyway, they are a good watch if you have a spare hour and watching/reading recovery and addiction based information is your type of thing!
