In Oregon, the movement's large intentional community of the early 1980s, called Rajneeshpuram, caused immediate tensions in the local community for its attempts to take over the nearby town of Antelope and later the county seat of The Dalles.

At the peak of these tensions, a circle of leading members of the Rajneeshpuram Oregon commune was arrested for crimes including an attempted assassination plot to murder U.S. Attorney Charles H. Turner as part of the United States's first recorded bio-terror attack calculated to influence the outcome of a local election in their favour; the effort ultimately failed. Salmonella bacteria were deployed to infect salad products in local restaurants and shops, which poisoned several hundred people.
