In relation with the two last posts, I will show you a video that I found on youtube (click here to see). This is an experiment carried out by Dr. Peter Witt in the 60's. Dr. Witt gave different drugs to spiders and saw how the aracnids made different types of web deppending on the type of substance that the doctor gave them. The conclusions were that:
*The spider with LSD made an unfamiliar web (not very effective to trap flies, I presume)
*The web of spider with caffeine was not affected, but the aracnid became extremly nervous
*The spider with marijuana became lazy and did not build the web
*The spider with alcohol, built the web and tried to find a mate that rejected it (oh dear...)
This is a very interesting experiment. We can not extrapolate spider's results to humans (we have a very different organisms) but we can see how legal drugs (like caffeine or alcohol) affected the behaviour of the spider (but not their work).
