Geneva Gas Protocol
The 1925 Geneva Gas Protocol provides:
Because suffocation in war, the use of any poisonous or any other gas and all such liquids, substances or devices is justifiably condemned in the general opinion of the civilized world; Also this ban should be universally accepted as part of international law that binds the conscience and practice of nations equally.
Publication: Top contracting parties accept this prohibition because they are not already a party to agreements prohibiting such use.
None of the countries has endorsed or agreed to the Protocol with any restrictions or interpretations restricting the chemical weapons to which it may apply.
