I posted this story about Novichoks before but people should have a read. Basically the whole point of Novichoks and other chemical weapons from that time was you developed two basic chemicals that could be easily hidden or produced in standard facilities that when mixed created the powerful nerve agent. This means they are easy to hide and easy to make even when you shut down all your specialist facilities.
Also, some of them were developed it seems specifically to ensure a slow and arduous death.
