Homeopathy is very popular in America, Australia, and other countries. Thing is, it doesn't work. There's no medicine in it, there's no science behind it, and tests have shown repeatedly and without question that there's no medicinal effect in it beyond that of a placebo.
And yet, homeopathic sugar pills are being sold next to real medicine at pharmacies across the planet, including RiteAid, Walmart, CVS, and Walgreens in the US. People take these non-drugs, spending billions -- billions -- of dollars on what is provably nonsense.
That's why the 10:23 campaign started, to show that homeopathy doesn't work. People all over the world are gathering this weekend to raise awareness of this. Homeopathy is not harmless. People are taking these pills instead of real medicine, in many cases making them sicker, and in far too many cases dying because of it.
James Randi made a short video to promote the campaign. If there is a local version in your area, go take a look and show them your support.
