Spiders On Drugs Make Terrible Webs

NASA proposed that drugging spiders and examining their webs could be a cost-effective method of testing for toxicity. Such tests were becoming increasingly unpopular (and illegal) when performed on "higher" animals. They recruited Araneus diadematus, a common house spider, for the task, and found that administering more toxic chemicals prompted the spiders to weave fewer complete web cells. This experiment was reminiscent of similar ones from the mid 1900s, in which Peter Witt gave spiders drugs such as peyote, LSD, and marijuana to observe their effects on web-making.
