I feel like this model is a perfect example of how the incentive structure of the pharmaceutical industry runs counter to pursuit of the best outcomes.
From what I understand anecdotally, psilocybin taken in moderate doses can have beneficial effects on depression and anxiety which last for weeks or months after the dose. This would be an amazing result by all accounts. A treatment which can be done every 6 weeks and still be effective would mitigate a lot of risks, like possible dependency and any toxicity which might be related to prolonged exposure. It seems to me that gets much closer to what we would refer to as a cure than a treatment.
But it seems like most of the clinical research is going into micro-dosing: i.e. how to make this something you would take every day to alleviate symptoms. I just don't understand the benefit of this approach other than the fact that it might be a better business model.
