One of the more interesting topics discussed in my high school health class – among the usual suspects of sexually transmitted diseases and the required viewing of the birth of a child – was the “placebo effect” and its relationship with alcohol consumption.
First coined by T.C. Graves in 1920, but studied far earlier in the 18th century by physicians and pharmacists, the effect describes the alleviation of whatever symptoms a patient may have without receiving any actual medicinal treatment while believing that they have. The belief is important – “placebo” comes from the Latin “I will please” – as the results depend on the patient’s conviction more than the treatment itself. By definition, it is a medicine that pleases the patient more than it benefits them. With alcohol consumption, the placebo can be used to display the expectancy of the effects of alcohol without actually having consumed it. In other words, if I expect to be drunk and know the typical actions of one who is drunk, then I will display those actions when I believe myself to be drunk, regardless of the amount of alcohol I have, or have not, consumed.
This varies from person to person, and there are variances in expectancy based on type of alcohol along with many other personal factors (i.e. people who have the same blood alcohol content can behave in drastically different ways). Additionally, this is not to take away from the fact that alcohol is a depressant and has specific psychoactive effects. However, the idea that intrigued me the most in high school, and continues to pique my interest to this day, was the idea that if one wants to be drunk, then they will be.
