The UK government has lost two more of its top drugs advisors after sacking its own chief expert on Friday.Dr. Les King and Marion Walker decided to quit the Misuse of Drugs Advisory Panel after Professor David Nutt was accused by the government of crossing the line into politics. Dr.Les King explained why he had resigned: “I felt I needed to support David because I think he was sacked unfairly. He was sacked for speaking his mind, and I think its a freedom of expression issue here,” he said. Professor Nutt was forced out after describing cannabis as less harmful than alcohol and nicotine, saying it was only upgraded to Class B for political reasons. And he accused Gordon Brown’s government of reclassifying drugs on a whim. Laws against cannabis in the UK were eased in 2004 on the advisory body’s recommendation, but the decision was reversed last year after much public pressure. Brown at the time said he wanted to send a strong message that use of the drug was unacceptable.
