Clairvoyance drugs of 1932

Want to see in the future? The April, 1932 issue of Modern Mechanix had the magic clairvoyance drug you'd been seeking:

A SOUTH AMERICAN plant called Yage is believed by natives to have the magical property of enabling the drinker to see great distances or through obstacles. Before the drinker falls asleep everything seems to be filled with hazy bluish rings. As the stupor deepens the sleeper sees vivid visions of things or people known to be somewhere else. This is the reason the drug is supposed to cause clairvoyance.
