The absurdity...

Reason Magazine - Hit & Run > Klosterman on Drugs:

"For a variety of reasons, the premise of taking a pill that changes your relationship with a memory seems scary. But we are already doing this all the time; our current means are just less effective. People get drunk in order not to care about things. People watch escapist movies to distract themselves from the stress of real life. Most significantly, we all distort the emotive meaning of our own past, usually without even trying; that's what nostalgia is. So let's assume that propranolol was abused to the highest possible degree; let's assume people started taking propranolol to edit every arbitrary memory that contained any fraction of mental discomfort. Ideologically, this would almost certainly be bad for the health of the world. But I still don't think it's something we could ethically stop people from doing."
