A Liberal Democrat leadership contender found his days at Oxford coming back to haunt him this weekend as an article he wrote advocating the use of hard drugs surfaced in a national newspaper.Chris Huhne, who is one of the favourites to take over from Sir Menzies Campbell, waxed lyrical about Opium, Heriod and LSD in a February 1973 issue of Isis magazine, which he wrote while an undergraduate at Magdalen College. The article, which was published under the heading 'Oxford escapism,' presents a beginners guide to a plethora of drugs. Of LSD he says, “Acid is manufactured in the labs and is the only drug which is getting cheaper . . . The considerable number of students at this university who drop acid are well-balanced highly intelligent people . . . if one is able to live with oneself . . . then acid holds no surprises.”But at the weekend the MP for Eastleigh claimed he couldn't remember writing the article, and said, “the views that were [expressed in the article] are certainly not my views as they are at the moment."
