The Loop, a drug welfare and service organisation, is to provide drug testing at a selection of UK music festivals this year after a number of drug related deaths.
The Montreal sites are modelled after Vancouver-based Insite, which was the first city in North America to have a legal, supervised injection site beginning in 2003.
New legislation streamlines the more than two dozen requirements previously needed to launch facilities, which offer supervision and sterile equipment.
The measure makes Vermont the ninth American state to legalise recreational cannabis use among adults and the first to legalise through a legislative process.
The bill will permit the preparation or possession of controlled substances in supervised premises and exempt certain users from possession charges under certain conditions.
