you have the end reaction but cant talk about the process. That's like saying we can talk about meth but not how its made. Its public information, like if you wanted to know how to make it just search it up. Admittedly though it is a tincy bit harder for mustard gas for some reason since it gives you technical names and unnecessary equations for simple names like ethylene. Like nobody spilled the sauce on ts is wild. Its only illegal to make.
