Anti-drug groups are angry at pop singer Sting who has called for legalisation of marijuana in the US.
The musician, 58, has said that America should spend the money it uses jailing users of the drug on tackling poverty and global warming, reports the Daily Express.
In a post on his blog, Sting wrote, "The War on Drugs has failed ut it's worse than that. It is actively harming our society. iolent crime is thriving in the shadows to which the drug trade has been consigned.
"People who genuinely need help can't get it. Neither can people who need medical marijuana to treat terrible diseases.
"We are spending billions, filling up our prisons with non-violent offenders and sacrificing our liberties."
Sting has urged people to support the Drug Policy Alliance (DPA), an activist group who campaign for those jailed for non-violent drugs offences to be released from prison.
He added: "For years, the Drug War has been used as a pretext to lock people in prison for exorbitant lengths of time - people whose crimes never hurt another human being, people who already lived at the margins of society, whose voices were the faintest and whose power was the least. Meanwhile, resources to fight genuine crime - violent crime - have been significantly diminished."
However, his comments immediately elicited an angry response from anti-drugs groups.
A spokesperson for DARE, which teaches schoolchildren about the dangers of drug use, has responded, "Sting should stick to singing and not meddle in matters he doesn't understand. We do not need pop stars coming out and making irresponsible statements like that."
