Morphine Sulphate 15mg. extended release

[GaryM]

OK, my dog had knee surgury and I was given a script for 6 tablets as noted in the title. We gave her 1/2 tablet when she first came home and after that no more were required.

Question one:
Should I dump the rest or keep them for a possible human use?

Question two:
What would the human dose be?

Question three:
What human condition would they be useful for that would justify self medication. None is an acceptable answer.

I'm not interested in "recreational" uses. Maybe I should just dump them.
