Synanon, originally known as Tender Loving Care, was a new religious movement founded in 1958 by Charles E. "Chuck" Dederich Sr. in Santa Monica, California, United States. Originally established as a drug rehabilitation program, Synanon developed into an alternative community centered on group truth-telling sessions that came to be known as the "Synanon Game", a form of attack therapy.[5][6]
Described as one of the "most dangerous and violent cults America had ever seen",[7][8] Synanon disbanded in 1991 after several members were convicted of offenses including financial misdeeds, evidence tampering, terrorism, and attempted murder.[9][7]
