2020 年，加拿大总人口约 3800 万，年龄 15 岁以上的 3200 万（出处），15 岁以上抽大麻的人数为 618 万（出处）
By the end of 2020, nearly 6.2 million people aged 15 or older, or 20.0% of Canadians in that age group, reported having used cannabis in the past three months (Table 1). This was higher than both the 14.0% reporting use before legalization and the 17.5% reporting use in the first months after the Cannabis Act was enacted.
