To make toxins kill humans faster is to panic them. panic the humans by making an anouncement or you could put the toxin on a florr with a computer or two and make sure you have lots of cycles(20 or so) and click on one computer at a time to make the humans run to stop the hacking thus the toxin causes more damage.
