Canada has became the first industrialised nation to legalise recreational cannabis, but a lawful buzz will be hard to come by in its biggest cities like Toronto and Vancouver, where stores are not yet open.
But provinces and businesses have struggled to prepare, and legalisation was pushed back from a July start to enable setting up distribution and sales networks.
Despite the early problems, the move is a political win for Prime Minister Justin Trudeau, who vowed to legalise cannabis during his 2015 election campaign.
The pledge was aimed at taking profits away from organised crime and regulating the production, distribution and consumption of a product that millions of Canadians consume illegally.
