The chemical weapon attack in Syria that has killed at least 70 people employed the nerve gas sarin. And, it is believed that it was the nerve agent VX that was used to assassinate Kim Jong-nam in a public airport. These uses of nerve agents violate the international Chemical Weapons Convention (CWC). While the Syrian government signed the CWC in 2013, it was never ratified, and of course, signatory agreement does not guarantee compliance. Nor do such treaties among nation states necessarily provide any security against the development and use of biological and chemical weapons by non-state actors. These events are disturbing and, we believe, portend a larger, and ever growing issue of how such neurological agents could be used, altered and/or developed anew as weapons.

International advances in brain science over the past decade are enabling ever greater capabilities to control neurological processes of thought, emotion and behavior. So, while the CWC and Biological Toxin and Weapons Convention (BTWC) prohibit development of drugs, microbes and toxins that can be made into weapons, these prohibitions are not absolute – many of these substances can be – and are – used in basic neuroscience research, or in research programs that seek to develop defenses against biochemical weapons. What’s more, new tools and methods with which to edit genes, such as CRISPR/Cas9, can make it easier to modify bacteria, viruses or certain toxins to be weaponized.
