> The problem is, no one wants to do those trials because rapamycin is cheap and generic. Why would Pharma spend money on something that they can't patent?

Same issue with psychedelics. However, they are so useful that people in the medical/therapeutic/academic fields are doing tons of research anyway.

Apparently big pharma is also trying to create their own psychedelics (there was an article about it on the front page of HN recently).

So far, the business seems like it will be on the assisted therapy side and everything that it entails. So more like services instead of products.
