Ignoring all the scientific evidence, Canada Health Minister Tony Clement will move to close Canada's only sanctioned safe-injection site, announcing it will appeal a British Colombia court ruling that Vancouver's Insite should stay open because reducing the risk of drug overdoses is a vital health service.

In a surprise ruling yesterday, the British Colombia Supreme Court supported Vancouver's experimental supervised injection clinic Insite - North America's first legal supervised injection site - and halted federal attempts to close the facility. That is very good news, but the ruling went even further.
