Every science experiment is valuable. Every time a scientist gets the chance to test an idea in a controlled setting, we learn something more about the world.
Sure, it might be hard to see the value of getting animals high and watching what happens, but these experiments have taught us some deeply valuable things. Thanks to science, we finally know the answers to the questions that have plagued mankind for years.
Like, how much cocaine does it take to get a rat into bebop jazz?
And how drunk do fruit flies have to be to experiment with gay sex?
Science has the answers.
