What is a Chemical Weapon? - American Chemical Society


tion of chemical weapons. One has to do with the status of old chemical weapons. Old chemical weapons fall into two catego-ries: 1) chemi-cal weapons produced before 1925 and 2) chemical weap-ons produced between 1925 and 1946 ‘that have deterio-rated to such an extent that they can no longer be used as chemical weapons’. Old chemical weap-
