In the United States, however, laws are still a little murky.

If the Liberal government in Canada passes legislation to legalize recreational marijuana - as it's widely expected to do after unveiling the plan on Thursday - the drug still probably won't be available for purchase until July 2018. In particular, the bill follows numerous recommendations made in the federal task force, released in late 2016.

While Canada had stopped enforcing pot laws for the past few years, this additional step toward full legalization is a huge leap for the country, and a major win for marijuana activists around the world.

Canada has legalised the use of medical marijuana in the country since 2001 and the marijuana for medicines is grown by 42 federally licenced producers.

O Canada, we stand on guard for weed.

"While the Canadian government is moving in the direction of legalization and regulation, the Trump administration and Attorney General Jeff Sessions seem more intent on reviving outdated and erroneous Drug War rhetoric than allowing science and facts to dictate public policy", Altieri said in a statement.

The press conference in Ottawa with Philpott, Minister of Justice Jody Wilson-Raybould, and Minister of Public Safety Ralph Goodale is scheduled for noon today.

The law would allow adults to legally possess as much as 30 grams of marijuana, around an ounce, in public. Households would also be allowed to grow up to four marijuana plants.

Now, new offences could be added to the Criminal Code under the Government's proposed legislation - including those for driving under the influence of drugs.

"Consequently, crossing with marijuana is prohibited and could potentially result in fines, apprehension, or both", according to the agency's statement. Details still need to be worked out, the government said, including how cannabis will be taxed and how Canada's provinces will regulate the retail network in which the product will be sold.

It would also be against the law to sell cannabis in a package or with a label that could be construed as appealing to young people, to include testimonials or endorsements, or to depict a person, character or animal.

- The existing program for access to medical marijuana would continue as it now exists.

"We want to make it more hard for kids to access marijuana". At present, only Uruguay has a national legal regime permitting widespread use of cannabis.

Down in the U.S., however, laws for recreational cannabis in the U.S. are still a work in progress.

The prime minister revealed legislation on Thursday that would make it legal to recreationally smoke marijuana across Canada. Such permits will cover only limited purposes, such as medical or scientific cannabis and industrial hemp.

The provinces also have to figure how they will regulate distribution. But cannabis remains a controlled drug, for the time being. Previously, the USA allowed patients with a variety of medical conditions to smoke marijuana in a variety of states since 1996, and four states have voted to allow the sale and distribution of marijuana.
