Full legalization of marijuana appears to be on track for July 2018, which will make Canada just the second nation in the world after Uruguay to completely legalize the cultivation, sale and possession of the drug for medical and recreational purposes.

The Liberal government said it plans to limit home marijuana growers to four plants per household, in line with the task force's recommendations. (The task force also recommended that plants be limited to 100 centimetres in height.)

The first regulatory system was implemented in 2001, before Stephen Harper's government took power. The next took effect in 2013, during Harper's tenure. Those rules would have prohibited home growing, but were ultimately reformed after a successful court challenge.
