That's... quite the leap. The entire point is that ethics committees are much more averse to human testing than to animal testing, so we're less conscientious about animal testing.
The quality of results from human testing is many orders of magnitude better; if you're willing to do it, there's no point in doing any animal testing.
2. Using humans for testing makes no sense bc. animals are exactly used to avoid early testing on humans
>> if you're willing to do [human testing], there's no point in doing any animal testing.
> animals are exactly used to avoid early testing on humans
These are two statements of the same idea.
