• Charles Manson (late 30s during peak activity): The Manson Family leader dosed young followers with LSD and methamphetamine to break down inhibitions, enabling coercive group sex and his apocalyptic control; older men in the orbit amplified the dynamic.[wikipedia]

• David Berg (Children of God, 50s-70s): This cult’s aging founder mandated “flirty fishing”—women prostituting for recruits—often amid drug use; Berg’s letters promoted free love laced with psychedelics.[cbc]
