On October 17, 2018, the Canadian government legalized the use and sale

of cannabis.

1. In your opinion, what were the consequences of this public policy?

on the cannabis use of Canadians?

Respond using a supply and demand graph.

2. Policy makers fear that a level of consumption of

cannabis too high leads to increased health costs

public. How could the government influence the quantity

balance in the cannabis market?

Respond using a supply and demand graph.

Several solutions are possible; choose one and detail

the mechanisms involved.

N.B.: Assume that the black market disappears as a result of the

federal legalization of cannabis.

3. Now release the hypothesis that the black market disappears after

the legalization of cannabis. Jean-Claude is a researcher at the University

from Montreal. He wants to study the evolution of the demand for cannabis

in the Canadian market (legal and illegal) after legalization.

However, there are no reliable data on the quantities sold to

black market.

Rolling paper is a good complement to cannabis and Jean-Claude

has a database on the quantities of paper sold to

ride before and after legalization. How could Jean-Claude

use these data to assess the evolution of the demand for cannabis?
