I'm assuming the prescription is just for bureaucratic purposes to determine who pays for the museum entry fees
Modern art was CIA 'weapon'

Science being the pursuit of knowledge through experimentation and peer review. "The Science" being the use of the imprimatur of scientific legitimacy as a political forcing function and illusion of neutrality to direct money and power in support of one's priorities.
Using science for power the same way the establishment used to use religion for power.
And lots of medicine isn't drug based! Would you write the same comment about the idea of a doctor prescribing extremely studied therapy such as CBD?
If this museum visit scheme came in the form of a pill, it would require years of trials and data proving its efficacy. Why are politicans allowed to bypass the EMA?
And second, quite a lot of medical interventions or lifestyle recommendation don't actually have "years of trials and data proving their efficacy" - never did. The years of trials thing happen with drugs, because they are high risk. It does not happen with run of the mill "try to rest on bed", "take walks" kind of advice.
