It's just so hard to know for sure if one is supplanting the other or if these are standard market trends—I have no problem believing either. I'm not surprised American's increasing taste for wine is slowing, though—It'd only become the industry we know today in the US since the early 2000's, it had to slow down sooner over later. Time will tell.

Also, I realize this was a Canadian study. It will be interesting 20 years from now what US data shows. Will we trade liver disease for pulmonary disease?

So, are there fewer car crashes, because fewer drinkers (I hear they can be pretty Harsh, in Canada, on repeat Offenders), and more crashes 'cause peeps get stoned?

We won't know what's really going on until it's federally legal and we've had enough time to study the impact and keep track of emerging trends. Wouldn't surprise me if more and more people replaced alcohol with cannabis though, cannabis has a significantly fewer downsides compared to alcohol.

It's a good topic, but of the three studies cited I'm guessing only the first was peer reviewed. We end of here with a good discussion and no conclusions. That leaves most readers to draw conclusions that affirm existing biases.

Caffeine and weed, the best brunch ever.
