But a large number suddenly felt no need for the drug on returning to the US. Their freedom from dependence on the drug contradicted everything scientists thought they knew about the biological mechanisms leading to heroin addiction.
The mystery of such locally limited addiction was solved by Stephen Siegel of McMaster University in Canada, in a study of drug addiction in rats. Just like humans, rats tend to develop a tolerance to a drug as doses increase in size. He introduced rats to the drug in a specially coloured cage with a specific scent. When they developed a strong addiction, he injected them with a large control dose of heroin, but half of the rats received it in their usual cage, whereas the other half moved to a new environment.
The results were astonishing. It is now known that the same principle applies to humans. Addicts who constantly take a drug after the same ritual in the same environment start to feel the effect of the drug even before they inject themselves with it.
The mere prospect of receiving the next dose triggers the effect of the drug. Addicted users then require ever-larger doses to achieve the desired effect. American soldiers who took heroin in faraway Asia, in a different climate, exposed to a very different way of life and the environmental shocks of a war zone, developed their addiction in that highly specific situation. When they returned to the U. There was a rule in boxing and wrestling that one of the contestants needed to wear red and the other blue.
They noticed the same effect in football. A new study, Joey T. Cheng, an assistant psychology professor at the University of Illinois at Urbana-Champaign, along with colleagues, explored the winner effect in a prestige setting. The researchers followed marching band members of a period two-months, sampling their testosterone levels before the study started and right after the study ended.
The Winner Effect
Each participant was surveyed about who they thought was most successful, skilled, or respected member of the band. The members were ranked and displayed so that each participant could see his standing or status within the social group.
In contrast, men who were ranked at the bottom showed a decline or little change in testosterone. Supercritical, badger, but all-round nice guy.
