Many Canadians on Reddit Tuesday night posted photos of themselves smoking marijuana, with captions saying things like, "My last illegal smoke."

That's because at 12 a.m. on Wednesday, marijuana became legal in Canada, the second country on Earth and the world's first major economy to legalize weed nationwide.

Canada rode the same wave that has led to legalization in nine U.S. states, plus Washington, D.C., and Uruguay, which was the first country to take that step. Many other countries, the U.S. included, are also now reckoning with their own marijuana policies.

But as Canadians file into dispensaries Wednesday, making their first legal purchases, New Jerseyans are still waiting for legal weed, as lawmakers haven't been able to get legalization across the finish line. It's also not clear when passage could happen in the state.

State Senate President Stephen Sweeney has called for a vote on legalization on Oct. 29, but the latest version of the bill hasn't been introduced into the Legislature yet. At the moment it's looking like that date could be yet another failed deadline.

Sweeney, Gov. Phil Murphy and other lawmakers had pushed to pass legalization by the end of June, but weren't able to get it done. Legalizing marijuana was one of Murphy's biggest campaign platforms and he's since called on the Legislature to send him a bill to sign by the end of the year.

Like Murphy, Canadian Prime Minister Justin Trudeau also campaigned on legalizing marijuana.

So what will legalization look like in Canada?

It varies, depending on the province. People at least 19 years old -- 18 in Quebec -- will be able to buy and use small amounts of marijuana. Retailers will include privately run shops, plus government stores and websites.

In some provinces, people will be permitted to smoke marijuana on the streets and in parks, while others will ban use in some public spaces. Except those living in Quebec and Manitoba, Canadians will be allowed to grow their own marijuana, up to four plants.

"It's great to see a prominent and sophisticated nation like Canada taking the lead on cannabis legalization," said Joe Lusardi, CEO of Curaleaf, which has a medical marijuana dispensary in Bellmawr. "Hopefully the U.S. will soon follow suit and lift federal restrictions, allowing the cannabis industry to flourish to its full potential, creating jobs and tax revenue."

Several of Canada's regulations will likely differ from the rules in New Jersey, should legalization pass.

Based on the current bill, the legal age to buy and use weed in N.J. would be 21; shops would be privately run, but overseen by the government; public use would not be allowed; and home-grow would not be permitted.

Other provisions in the bill are likely to change, but the above regulations have been mainstays in various versions of the legal weed bill discussed this year.

The finer details of the legislation are still being worked out and the discussions look likely to bleed deeper into the fall, likely pushing up against Murphy's year-end deadline.
