What came beforeAI-assisted
Cannabis has been used by humans for thousands of years, with evidence of cultivation dating back to ancient China around 12,000 years ago. The plant was valued for fiber, seeds, and medicinal properties across Asia, the Middle East, and eventually Europe.

Who was involvedAI-assisted
Canadian Prime Minister Justin Trudeau's Liberal government championed the legalization effort as part of their 2015 election platform. Health Canada and provincial governments worked to establish regulatory frameworks for production, distribution, and sales.
TimelineAI-assisted
The Cannabis Act was introduced in Parliament in April 2017 and passed through multiple readings and committee reviews over 18 months. Legalization took effect on October 17, 2018, one month after royal assent, allowing retail sales to begin.
What happened
Cannabis is a genus of flowering plants in the family Cannabaceae that is widely accepted as being indigenous to and originating from the continent of Asia. However, the number of species is disputed, with as many as three species being recognized: Cannabis sativa, C. indica, and C. ruderalis. Alternatively, C. ruderalis may be included within C. sativa, or all three may be treated as subspecies of C. sativa, or C. sativa may be accepted as a single undivided species.
