Canada became the first industrialized nation to legalize recreational cannabis on Wednesday, but a lawful buzz will be hard to come by in its biggest cities like Toronto and Vancouver, where stores are not yet open.

The day was historic for the country as Canadian adults can now legally smoke recreational marijuana after nearly a century-long ban. But provinces and businesses have struggled to prepare, and legalization 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 legalize cannabis during his 2015 election campaign. The pledge was aimed at taking profits away from organized crime and regulating the production, distribution and consumption of a product that millions of Canadians consume illegally.
