Raas,
The experts you are referring to were fired by the government after the results of government funded research failed to coincide with the then current policy on drugs, based on the out dated Misuse of Drug's act.
Since some of us appear to have missed a beat, back in October 2009, in the run up to the last election, the Head of the government subsidised Advisory Council on the Misuse of Drug's (ACMD) was fired from his position after giving a private lecture at some UK uni where he presented the finding's of a government subsidised study designed to rank the 20 most prominant drugs in terms of their relative harms. The the labour government decided that since alcholol was found to be in the top five most dangerous drugs, (while cannabis, exctacy and lsd were not) that instead of allowing their own advisory panel to present these findings in public, they would instead choose to sensor these findings.
The experts concerning this issue are David Nutt, who was fired, along with 7 other prominent scientists who resigned in protest.
If that doesn't do it for you, a couple of years previously to this, the chief scientific advisor to the government, Sir David King, resigned from his post stating that his whole position in government was an absolute waste of time due to the simple fact that he couldn't find any more than a handful of active politicians who even had the semblence of a grasp of basic scientific principles that were an absolute necessity if he was to able to communicate effectively with any of them.
I don't know which experts you have in mind Raas but I have no doubt in my mind over which one's I put my faith and trust in. Care to offer up any names?
