I believe this statement to be true. I found the original article for the University of South Florida written by Cassidy Demarten. The article discussed the process of David Tanasi and his team discovering the DNA in the mug. Tanasi is a professor and Director of Digital Exploration. Furthermore, I found Cassidy's public resume, discovering she has years of expertise in communication and journalism. The article also mentioned Branko Van open. After doing some research, I found that he focuses on the religious identification of Greek artifacts. Lastly, I found multiple news articles confirming the recent discoveries of psychedelics in Bes mugs.
