I'm gonna go out on a limb here and say she may have easily been a closet alcoholic and hid it well from her family. It may not have been unusual for her to be drinking that amount even early in the day. Under most circumstances she probably even would have been functioning close to normal if she was a regular drinker.

She may not have been a regular pot smoker though, and I think (my opinion) is that is what caused the extreme disorientation. Pot by itself normally wouldn't cause something like this, but on top of alcohol it can be disastrous.

It's sort of a known thing among partiers that you can smoke and then drink without too many ill effects. But drinking and then smoking afterward will likely have you flat on your back sick as dog.

I made the mistake of smoking after I had been drinking a few times in my youth and regretted it every time. I wasn't a novice with either, but the combo would have me on the floor with my head in my hands not even able to focus my eyes.

Lots of people can drink and then smoke pot, but I'm guessing she wasn't one of them.
