All the drugs tested reduced web regularity except for small doses (0.1–0.3 μg) of LSD, which increased web regularity. [12] The drugs were administered by dissolving them in sugar water, and a drop of solution was touched to the spider's mouth. In some later studies, spiders were fed with drugged flies. [14]
The effects of some drugs can be measured by examining their effects on a spider's web-building.

Sending spiders to space seems like a good idea (because, science), but arachnids apparently have their own notions about living in space. NASA researchers first sent spiders to space in the 1970 ...
The video purported to show the behavior of wood spiders given various drugs, such as alcohol, caffeine, and THC, a mocking reference to the 1940s research of Peter N. Witt, who showed that giving drugs to spiders alters their web building behavior. [12]
Spiders also have several adaptations that distinguish them from other arachnids. All spiders are capable of producing silk of various types, which many species use to build webs to ensnare prey. Most spiders possess venom, which is injected into prey (or defensively, when the spider feels threatened) through the fangs of the chelicerae. Male ...
