cocaine, power and irresponsibility

here is a crackpot theory i thought of while reading stories about cocaine on the BBC website.

Exhibit 1:
By testing the waters of the river Po for the presence of benzoylecognine, a chemical formed by the metabolism of cocaine, Italian scientists find that the region with about five million people consumes at least 1 500 kilos of cocaine per year. Cocaine use is almost triple what officials had previously estimated. link

Cocaine use is higher than you think.

Exhibit 1a:
Similar research in Oregon showed that on weekends, the sewage from water treatment plants servicing affluent communities shows high cocaine and ecstasy use. link

Rich people like to use cocaine on the weekends.

Exhibit 2:
A European television station took swabs of toilets from toilets in EU parliament buildings, finding 41 of 46 toilets tested to be positive for cocaine (not benzoylecognine). People are snorting cocaine in bathroom stalls in the parliament building. They tested other buildings. Cocaine wasn't found in German high schools. link

People in government like to use cocaine.

Exhibit 3:
Researchers in Boston found that the amygdaliae (a part of the brain) of cocaine addicts were smaller than those of non-addicts. People with smaller amygdaliae are not good at identifying the possible consequences of their actions before they take them. It is unclear whether cocaine use shrinks the amygdalia or whether people with small amygdaliae are predisposed to addiction. link

Cocaine users' perceived bad luck is in fact carelessness.

Interesting questions:

Do people in power use more cocaine than the rest of us? Do people in power have smaller amygdaliae? (either a priori or because of cocaine use) What other factors correlate with small amygdaliae?
