I'm sure their files have been paid necessary attention to deep inside some 3-letter agency. One hell of a coincidence:

https://en.wikipedia.org/wiki/Haight_Ashbury_Free_Clinic

"Louis Jolyon West—a LSD researcher involved in MKUltra—lived near the clinic, and was allowed by Smith to recruit clients for experiments.[7]"

All files related to MKUltra were destroyed in 1973, at the orders of CIA director Richard Helms. So, not so much.

Guess the CIA really didn't want their experiments with Charles Manson to come to light.

(Yes, yes, there only exists circumstantial evidence of a CIA/Manson connection. Because they burned the files.)
