Effect of psychoactive drugs on spider’s ability to build a web.
In 1948, Swiss pharmacologist P. N. Witt started his research on the effect of drugs on spiders. Witt tested spiders with a range of psychoactive drugs, including amphetamine, mescaline, strychnine, LSD and caffeine. The spiders spun bizarre webs and Witt used different statistical tools and image processors to analyse them. The more toxic the chemical, the more deformed a web looks in comparison with a normal web.
