Chavez, one of five charged, expressed remorse and surrendered his medical license.
He admitted to illegally supplying ketamine to Perry through another doctor.

Authorities allege a network of individuals exploited Perry's addiction for profit.
Two other defendants, including the so-called 'Ketamine Queen,' face upcoming court dates.
