Authorities say a student confessed to buying LSD from a secretive site on the internet then selling the drugs from his East Stroudsburg University dorm room.
The Monroe County district attorney has charged 20-year-old Michael Mancini, of Landenberg, Chester County.
The DA used information gathered by campus police and the county drug task force to charge Mancini late Wednesday. He faces a preliminary hearing May 17.
Authorities acted on a tip and intercepted a letter Mancini received from Fun Stuff LLC in Wailuky, Hawaii last month.
They say it contained a plastic bag marked "Mint Condition" which contained two Pokémon cards. Pressed between the card was an LSD-soaked piece of paper with 25 smaller squared "hits" of the drug.
Mancini's attorney didn't immediately return a call Friday.
