103 NPPES records list addiction (substance use disorder) psychologist (103TA0400X) as their primary taxonomy with a practice address in California: 0.3 per 100,000 residents against 0.2 nationally (50 states and D.C.). San Diego has 8 of them (8%).

A record is a registration a provider made and keeps up to date: it shows neither that the provider is licensed nor that they still practice there. The state's own license search is the check.
