Canada becomes second country to legalise recreational marijuana
The nationwide market for cannabis opened on Wednesday at midnight amid lingering questions about the impact on health, the law and public safety.
Information has been sent to 15m households about the new laws and public awareness campaigns.
But there remain concerns, including about the readiness for police forces to tackle drug impaired driving.
Uruguay was the first country to legalise recreational marijuana, although Portugal and the Netherlands have decriminalised the drug.
Canadian provinces and municipalities have been preparing for months for the end of cannabis prohibition.
Provinces and territories are responsible for setting out many of the details for where cannabis can be bought and consumed within their jurisdictions.
This has created a patchwork of legislation across the country as jurisdictions choose more or less restrictive frameworks for selling and using cannabis.
