On air: Should drug users be paid not to have children?
This topic was discussed on World Have Your Say on 19 October 2010. Listen to the programme.
That's the arrangement set up by an American concern, Project Prevention - and the first man in the UK to take advantage has done so today.
"John" - not his real name - received £200 for being sterilised. He says he should "never be a father."
The founder of Project Prevention, Barbara Harris, set up her charity in North Carolina after adopting the children of a crack addict. She has told the BBC:
The birth mother of my children obviously dabbled in all drugs and alcohol - she literally had a baby every year for eight years. I get very angry about the damage that drugs do to these children.
But a drug charity in the UK has said that it "exploits very vulnerable people who are addicted to drugs and alcohol at probably the lowest point in their lives."
Is it right to pay drug addicts not to have children?
