I think it will be huge
Social drinking is common place and I think that cannabis drinks will garner a good share of the market.
The challenges are taste acceptance
Getting the delivery of the "high" consistent with a normal drinking timeline
Calorie count will also play a big role especially with women
on the other side, no hangover
There will no doubt be a learning curve to understand how it reacts with you, but this will become mainstream
Full disclosure: I am invested in many MJ stocks including Hexo (Molson joint venture partner)
