The Argentine government has launched a major campaign against cocaine, just two days after the country's former football star Diego Maradona began treatment at a clinic in Cuba for his addiction to the drug.

Hundreds of posters, bearing the slogan "Damned cocaine", have been put up across the capital, Buenos Aires.

A government spokesman said the aim was to highlight the dangers of drug abuse, especially to young people.

He said it wasn't wrong to link the campaign with Maradona, as his case demonstrated the harm cocaine could do.

Maradona was diagnosed as having a severe heart conditiion, after being admitted to hospital suffering from a cocaine overdose. He's expected to say in Cuba for at least three months.
