London: Prosecutors worldwide are too lenient on celebrities who use drugs, sending a dangerous message to young people, the United Nations said on Wednesday in its global report on illegal narcotics trends.

The panel said too many governments primarily targeted ordinary addicts and street dealers while doing too little to tackle the larger narcotics gangs, and letting high-profile users walk free.

Board member and report author Hamid Ghodse told a news conference in London, "The fact is that when a celebrity uses drugs, he or she breaks the law."

He added, "Young people are quick to pick up on, and react to, perceived leniency ... It also makes people become cynical about drug enforcement."

He refused to name any particular individuals or countries considered too soft on famous users.
