The Church of Scientology is loudly voicing their strong resistance to what they call "psych drugs". It is therefore ironic that the founder of Dianetics and Scientology, L Ron Hubbard, was taking a "psych drug" when he died. This is not unusual in itself, since bitter old men often go psychotic when dying. Witnesses testified that Hubbard died acting like a raving lunatic.
This is from the 1983 edition of the Physician's Desk Reference, pg 1571. It was a couple years out of date when Hubbard died. Vistaril is the psych drug found in Hubbard's body.
