”Magic mushroom” edibles sold at smoke shops and other retailers might be missing psilocybin but can contain undisclosed ingredients, according to a joint study published Thursday.

Oregon State University researchers collaborated on the analysis with Rose City Laboratories, a state-certified testing lab in Portland, and the manufacturer Shimadzu Scientific Instruments.

The edibles, including gummies and chocolates, contained caffeine and synthetic psychedelics. Richard van Breemen worked on the research and is a professor of pharmaceutical sciences at OSU.

“Syndelics represent a rapidly growing area of drug design, where medicinal chemists create novel compounds inspired by known psychedelic agents like psilocybin and LSD,” van Breemen said in a press release. He joins us with details of the study.
