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.
I would be at least a bit worried too, but unfortunately the only reason this exists is because corporations decided to wall off access to producing their drugs legally so they could continue to exploit vulnerable people for profit.
For a lot of the people using this tech, it’s the only way they’ll get life saving medication, and without it, they’ll die. If that’s the kind of gamble they have to make, a possible risk of impurities or negative reactions is better than the considerably less desirable option of death.
