The impossible-to-resist Stone Age/stoner pun will be gaining currency thanks to a breakthrough discovery on the Caribbean island of Carriacou. Researchers "have found equipment used to prepare hallucinogenic drugs for sniffing" including ceramic bowls as well as tubes for "inhaling drug fumes or powders." The Telegraph writes that while ancient substance abuse has "long been suspected", and that "archeologists have suggested that humans were extracting mind-expanding drugs as far back as 5,000 years, sufficient proof has not emerged until now. According to the story, it is believed that the street drug of choice back then wasn't ganja but "cohoba", a hallucinogen processed “from the beans of a mimosa species." There were no reports as to whether drug-sniffing German shepherds assisted in the investigation.
