I read a Motley Fool article on this last night: https://www.fool.com/investing/2018/08/15/corona-and-cannabis-the-perfect-match.aspx

Some of the key excerpts I noted from this article that refer to the potential size of the recreational cannabis market are as follows:

In anticipation of growing demand for cannabis products because of recreational use, and ostensibly, to insulate itself against the risk marijuana sales come at the expense of beer, wine, and spirits sales, Constellation Brands made a $245 million Canadian ($191 million) investment in Canopy Growth last October.

Constellation provides Canopy Growth with global marketing and distribution experience that may allow it to win a sizable share of what ArcView estimates will be a $57 billion market by 2027.

What to watch next
Constellation and Canopy Growth believe there's an opportunity to market cannabis-based beverages, but the size and scope of this deal suggests Constellation believes the marijuana market will rival the tobacco and alcohol markets in terms of sales and profitability.
