If I have the medical aid in dying pills how long is the shelf life for these drugs? How long can I keep them on hand?

No euthanesia. What is your diagnosis to ask this? US does not practice medical aid dying, as you put it.

This site does not promote suicide but if you have a terminal illness discuss with your PCP for direction.

I have seen only one patient with terminal ALS using doctor aided death. Write again with all the details.
