Canada just legalized recreational pot

(CNN) – People in Canada are cheering, enduring long lines and honking their car horns in support as the country’s first marijuana dispensaries open their doors Wednesday.

“I’m having a plaque made with the date and time and everything. This is never actually going to be smoked. I’m going to keep it forever,” said Ian Power, who was among the first to buy marijuana in St. John’s, a city in the country’s easternmost province of Newfoundland and Labrador.

Like Power, hundreds are now legally buying recreational marijuana all over Canada but not without adjusting to a few rules.

As marijuana enthusiasts continue celebrating this historic day for Canada, here’s a quick primer to get you up to speed.

Who can buy marijuana in Canada?

Adults of at least 18 years old will be allowed to carry and share up to 30 grams of legal marijuana in public, according to a bill that passed the Senate in June.

They will also be allowed to cultivate up to four plants in their households and make products such as edibles for personal use.

Where can I buy it?

The supply of recreational marijuana could be limited, at least early on, in some stores.

Officials in Nova Scotia and Manitoba said they won’t have a large selection, at least not on the first day, CNN affiliate CBC News reported.
