Canada is set to become the first G7 country to legalise cannabis after lawmakers on Monday passed a bill that would allow free consumption ... Passed 205 to 82 in the House of Commons, the legislation must still pass the Senate (could delay, but not block) and receive royal assent by the Governor General before becoming law, likely September. Legalising weed was a 2015 campaign promise of Prime Minister Justin Trudeau, who acknowledged smoking a joint with friends "five or six times" including since being elected as an MP. Liberal government's point-man on pot, Bill Blair, said it was "probably looking at a date of implementation somewhere toward beginning of September, perhaps mid". Uruguay approved recreational use five years ago and nine US states and Washington have done so, but Canada will be the first G7 country to take the step ... Trudeau insisted his government would move to legalise production, sale and consumption before facing the electorate again in 2019 ... Health Minister Ginette Petitpas Taylor said, "It is already possible for Canadians to grow cannabis for medical purposes and we absolutely believe legislation should be consistent when it comes to recreational cannabis" ... Canadians over the age of 18 (19 in some regions) will be able to buy a gram of pot for about C$10 or less, from a patchwork of authorised private and public retail stores or by mail order, with each province and territory responsible for setting up distribution. Personal possession will be limited to 30 grams (one ounce). Statistics Canada has estimated the market will be worth C$5.7 billion ($4.5 billion US), based on last year's consumption data. Finance Minister Bill Morneau estimated the cannabis tax haul will be about C$400 million, but Ottawa has agreed to retain only 25% of these monies, with the rest going into provincial government coffers. Last month Trudeau said the world was closely watching Canada's pot plans and predicted other countries might follow suit. "There is a lot of interest from our allies in what we're doing" he said. "They recognise Canada is being daring ... and recognise the current regime (of prohibition) does not work, that it's not preventing young people from having easy access to cannabis". The prime minister argued that creating a regulated market would take the 'drug' out of the hands of crime groups and "better protect communities and children". Yet he added the allies he spoke with ahead of a recent G7 summit in Quebec "are interested in seeing how things go ... before they try it" without specifying which nations.
