In Orange County, California, where rehab centers are concentrated, out-of-state visitors had 159% more overdoses than expected compared with out-of-state visitors elsewhere in the state. The researchers suspect predatory operators are partly to blame.

Common sense says more rehab centers should mean fewer overdose deaths. Researchers in Orange County, California, found the opposite: where rehab clinics are packed together, out-of-state patients end up in the emergency room for overdoses far more often than elsewhere in the state.
Boyd, 24, came from Chicago to get sober at a clinic in Orange County. He was admitted three times, yet began using fentanyl, a potent synthetic opioid, inside the facility, and died of an overdose.
Insurance billing powers a revolving door
The researchers argue the problem lies in where insurance money flows. Federal law requires most private health plans to cover addiction treatment. The goal is sound, but it has drawn operators who see easy money.
A common scheme is to recruit patients with good insurance, then bill for unnecessary or substandard services at inflated prices, sometimes $3,000 a day per patient. When coverage runs out, the patient is discharged. If they relapse, they can be readmitted and the billing starts again, a revolving door.
Out-of-state patients are the easiest targets
Out-of-state patients are especially vulnerable. Some clinics offer free one-way plane tickets and housing, and third-party 'patient brokers' earn kickbacks for every person they bring in.
Before arriving, patients cannot see the real conditions. Once inside, they are cut off from family and friends and depend entirely on the facility. Those far from home often cannot even afford the trip back.
The numbers are stark. Orange County had 14 treatment centers per 100,000 residents in 2019, against a national average of 5. Compared with out-of-state visitors who went elsewhere in California, out-of-state visitors treated there for overdoses were 159% above expected, while local residents were only 10% above.
For anyone weighing treatment and their families, the most important rule is simple: do not travel far to enter a facility you have never seen in person.
Why it matters
Treatment capacity is not a safety signal when clinics earn by billing insurers for each readmission. Where centers multiply, more patients may be kept cycling through care rather than recovering.
