The friends, neighbours and family of Leah Betts, the teenager who died three weeks ago after taking the drug ecstacy, mourned her yesterday at her funeral, which was filmed for a drugs prevention video to be shown in all British schools, writes Alex Bellos.
Leah collapsed at her 18th birthday party after taking an ecstasy tablet. A photograph of her on a ventilator became a powerful image in the propaganda war against drugs.
