FWIW, I use them for such purposes (and for a zillion others) all the

have a hundred or so left.
The silver cannot possibly get out of the film without help from water
and chemicals (or fire), but possibly the film base might contain
something that oozes out in dry state. I´ve never worried, and never
observed any ill effects.
The real old ones in my collection are aluminum, and that´s probably
not safe.

Is it safe to use the plastic film cylinders -- some people call it
canisters -- for storing medicines, either liquid or solid? If there
are traces of silver or other chemicals in the cylinders, how do we
remove them?
