No different, really than people who have drink at the end of the day.
Real problems would have been near the start of the list, with getting stoned near the beginning instead of the end.
I think the same list that ended not with the weed but with “buy six pack Get Blitzed” would be equally funny.
I make to-do lists all of the time. This person’s list shows how much he has reduced his mind’s capacity to function.
