Many reasons
- there are plenty of quacks who already con people
- people who do actually believe their product works, but it doesn’t
- things that may work but also may kill you (remember that drug trial in London a few years ago that had got through all pre-human trials without a problem?)
- placebo is real, and the pre-approval access ideas generally are a pay-to-play concept, and I’m not sure people would want to pay for a blinded treatment
- people talking about these trials always seem to say “once basic safety tests are done”, but phase 1 and 2 are the basic safety tests. Phase 3 require enough people that drug companies are often actively working to find participants.
The real problem here is that universities etc keep posting hyperbolic articles saying “we have found something that may cure X”, with the rider for studies and fda approval are necessary.
Laypeople interpret that as meaning the fda approval is preventing them from accepting patients for approval, when typically the component in question is not remotely close to a treatment:
- it’s just binding to a target invitro.
-There’s no information on what happens one it has bound.
- there’s no evidence it can even get to the target invivo anyway
- animal trials are only advisory. There have been many super effective drugs and vaccines that have no effect in humans
- can the get past the immune system? Will the immune response kill a person
- I’ve seen articles about compounds that would (and turn out to be) toxic
Etc etc
But all a patient sees is the “may cure X” bit and so demands a right to use the drug.
That’s why these things are a bad idea
