In chapter 13 of the excerpt Chasing the Dream, the author begins talking about an experiment he had seen being conducted on rats which to him at first seemed “intriguing” but he is able to experience on his own later on. Johann tests out a few theories he has on the concept of addiction and what may be the cause of it. One of the many examples he uses is a “rat park” in which he creates two different environment for two sets of rats, one filled with everything a rat could dream of and the other environment was just a lonesome rat. through this experiment he was able to determine that the environment of a person plays a huge part on their addiction because the person filled with wheels and other rats barely touched the morphine yet the rat which was by itself consumed a lot of the morphine. He also tested the effect of addiction on the soldiers from Vietnam which ended up having a completely different outcome then expected. Through these experiments he was able to see that many of those who were weak were a result of a bad childhood. Having a bad childhood prevents people from being able to form a healthy relationship with other people hence being prone to a life of loneliness and being able to get addicted faster/ easier. Johann says that if the rats and soldiers could not get out of this world physically they would get out mentally which is why they resulted to drugs, to get away from the pain. He also addresses a very important point when he says the problem is not the people but the culture, there needs to be ways to make a “social recovery”.
