Can elves die by being poisined???

[Alatariel]

Eol - it is in appendix A of Lord of the Rings (if you have copies where the book is broken up into it's three parts, it's found at the end of Return of the King under: "Here follows a part of the tale of Aragorn and Arwen."

Poison is also a form of being slain, so i believe that elves can die of poison

I guess it depends on your definition of "slain." I always took this to be a violent death, such as being run through with a sword. As far as I understand, elves are immune to things like extremes in temperature, so I would imagine that they would also be immune to poisions.
