Ancient Morphine-usable?

[Magni]

So, SWIM just bought a bit of liquid morphine from a friend. I don't know exactly how old the morphine is, but just tonight SWIM's friend shoved the needle so far into the bottle that the wax top of it broke, and fell into the bottle.

Also, when it was going into the needle, this morphine still had small bubbles in it, regardless of how much SWIM flicked the needle. SWIM is not very experienced with this sort of thing, so SWIM would like to know if SWIY thought this stuff was still good, and if so, how long it would keep if left opened (although perhaps with a piece of scotch tape over it).

Thanks for the help.
