Well, not to mention there were clocks on at least their cell phones and the laptop and, IMO, as students, are in the habit of checking clocks regularly.
I happen to live somewhere where medicinal marijuana is legal, and my town happens to be particularly known for its "herb friendly" status. I wrote out this whole other thing to say, but it was long and rambling and personal, so I'm just gonna say that if you want to learn more about how certain drugs and drug combinations affect people, as in lots and lots of anecdotal information, this is a good site:

"Erowid: Documenting the Complex Relationship Between Humans and Psychoactives."
FWIW, my personal OPINION re: the drug use, is that if this loss of memory is accurate, true, and real, then it is completely absurd, IMO, that it could be caused by smoking only marijuana or hash. Add in a decent amount of alcohol and it's more believable, IMO. Add in a some sort of benzo instead and it's getting closer. Add in some sort of benzo AND alcohol, then that could convince me enough that this hazy memory issue, which may or may not have caused/influenced a conjuring of a murderous black man, could have happened. However, IMO, someone in that state wouldn't remember murdering someone, either, but someone who ingested several types of depressants, of course, would most likely pretty quickly be seriously passed out for many hours, IMO.
So, uh, take that as you will...I'm just thinking and typing here....
