An engineer at a TV station in San Francisco volunteered to help a university repair a vintage synthesizer last year and ended up tripping on LSD.

The fact it was built by a bunch of Deadheads in the 60’s in combination with the perfect conditions for keeping LSD potent (being stored in a cool, dark area) led to how this man was able to be affected by it still.

He noticed the crusty residue on the synthesizer and picked it off and tripped for about NINE hours from there!
