It activates the same chemicals in your brain as cocaine! 
Well, yeah, there are only ~~three~~^[@Neuromancer49@midwest.social corrected me] a few neurotransmitters. That's not saying much.

It contains more germs than a toilet seat! 
Germs like moist surfaces. We don't want germs on our toilets, which is why we make them out of porcelain, which is hard, dry, non-porous, and easy to clean.
If it had more germs than your colon, then I would be concerned.

In reality they were all wrong to a significant degree and also usually contributed significantly to some aspect of what is taken for granted as the 'correct' scientific knowledge
For example, it's been known Mendel must have faked his data for almost a hundred years, but that doesn't make Mendelism wrong (after you strip out the stuff that is wrong)
Does Wikipedia have a license to peddle copium of this purity?
Not exactly, the only thing that he was correct about in that regard was the existence of a material carrier of heritable information. Literally everything else he conjectured about it was wrong like thinking that it would be continuous rather than discrete and so on.
