Ancient hunter-gatherers who depended on the wild, before agriculture was invented, not only forged for food -- they foraged for marijuana, according to science.
The medical benefits of cannabis, while still officially denied by the U.S. government (which holds a patent on the damn stuff) was well understood by our forebears, probably instinctively, at least 12,000 years ago, reports Stephen Morgan at Digital Journal.
A team of anthropologists from Washington State University, led by Dr. Ed Hagen, wanted to see how cultures worldwide used cannabis historically. They especially wanted to see if ancient marijuana users were subconsciously influenced more by health reasons than just wanting to get high.
Humans throughout history have probably sought out cannabis, in the same way we searched out foods beneficial to us, according to Dr. Hagen.
"In the same way we have a taste for salt, we might have a taste for psychoactive plant toxins, because these things kill parasites. If you look at non-human animals, they do the same thing, and what a lot of biologists think is they're doing it to kill parasites," Dr. Hagen said, reports Ellie Zolfagharifard at the Daily Mail.
