Pubdate: Sun, 28 Sep 1997 Source: Reuter LONDON, Sept 28 (Reuter) The British government on Sunday dismissed calls for cannabis to be made legal and said a national newspaper which supported changing the law was irresponsible. Home Secretary Jack Straw was reacting to calls by the Independent on Sunday newspaper, backed by former Beatle Paul McCartney and entrepreneur Richard Branson, for him to repeal a 69yearold law which outlaws the drug. ``There is a profoundly pessimistic assumption behind what the Independent on Sunday says and that is that we are losing the war on drugs. It's not true,'' Straw told independent television. ``What I regard as so irresponsible about those who say we should decriminalise possession of small amounts of cannabis is this one thing which would follow, as night follows day, is that consumption would shoot up.'' The newspaper devoted more than a page to an examination of the case for decriminalisation, with endorsements for the idea from senior doctors and former highranking policemen as well as McCartney and Branson. ``If alcohol is a tiger, then cannabis is merely a mouse,'' wrote editor Rosie Boycott. ``No one has ever been disfigured by a joint.'' More than 300 people who joined a demonstration in London's Hyde Park on Sunday to call for cannabis to be made legal were handed hash cakes and cannabis resin as police looked on. The Independent on Sunday said police were increasingly cautioning people found in possession of cannabis rather than prosecuting them. Cautions were given in 47 percent of cases in 1992 against one percent in 1981, it said. Meanwhile researchers at Exeter University in western England issued details of a survey which they said showed that three in 10 British schoolchildren aged 1415 had tried cannabis at least once.
