Some of us aren’t binary brained morons ffs.
Big Pharma - especially US pharma, are largely profiteering twats. However that doesn’t mean that they don’t actually produce some fantastic life saving or life extending drugs.
Testing regimes have moved on somewhat since the 60’s btw. New cancer drugs for example, have to go through 5 year human trials before being certified. Does that mean that there can never be issues with certified drugs in the future? No, as long term effects can never be ruled out, however much they try. Unless you literally had drugs on a human lifespan testing regime before release.
