It would be a conundrum not unlike I experienced during Post Exams, when I spent the whole week high off my ass because I didn't know whether or not I was going to graduate (I only found out the Friday before commencement -- I graduated).
You get high so that you are very stoned all the time, and start to wonder if you will always be high, except that the high you will always will be normal, so you will always feel a little off, but not necessarily different, which takes away some of the positives about getting high, because getting high is BETTER than normal. But you're high, so that should be better than normal, tek-nik-kally, but it's not.
I mean, how do we know we're high if we never come down?
