Sharing because I found this very interesting.
The Four Thieves Vinegar Collective has a DIY design for a home lab you can set up to reproduce expensive medication for dirt cheap, producing medication like that used to cure Hepatitis C, along with software they developed that can be used to create chemical compounds out of common household materials.
Obviously the people who would benefit most from this technology would prefer a doctor and pharmacy to be involved as well. The point is that personal preference doesn’t really mean much when the preferred option is inaccessible and the alternative is death or a dramatically reduced quality of life. You do the best with what you have.
