The New York-based company's cannabis investment is being closely watched since it's the first time that big alcohol has entered the so-called Green Rush.
The scrutiny only intensified this week after US Attorney General Jeff Sessions rescinded the Obama-era policy that let federal prosecutors look the other way while states set up their own markets for marijuana. The announcement followed California's launch of a legal marketplace on January 1.
For now, Sands says Constellation and Canopy are developing a non-alcoholic cannabis beverage for release when Canada's government legalises pot drinks, expected in 2019.
Constellation could certainly use a new growth source. Its sales of wine and spirits have persistently fallen, and investors are starting to notice.
Shares of the company fell as much as 4.2 per cent to US$216.25 today, the most intraday in more than 10 months, after it reported declines in volume and sales for wine and spirits.
Constellation has ridden the strength of its imported Mexican beer to become an investor darling - 15 analysts recommend buying the shares and none recommend selling them - but even growth in that category was less than what some had expected.
