The June 27, 2022 9-0 ruling by the Supreme court in the Ruan/Khan case is a major victory for medical professionals and patients. 

What the ruling did was made it so that law enforcement & prosecutors are only allowed to enforce  CSA 841 as written, not as they choose to interpret it.
They can't prosecute medical professionals for exercising clinical judgement or acting in the best interests of their patients. They have to PROVE beyond a reasonable doubt that the *intent* was to deviate from the standard of care. See Justice Breyer Opinion for additional details.

This will relieve a tremendous amount of pressure from prescribers and pharmacists who are exercising their professional discretion. This ruling is a significant accomplishment towards restoring patient-centered care. 

It will not have an impact on DEA registrant revocations. They are covered under 21 USC 824 which has a inconsistent with the public interest clause. It's under this clause that they utilize a subjective definition of medical practice to revoke Controlled Substance (CS) registrations.

A review of the CS revocations for this year shows that the Drug Enforcement Agency (DEA) and the Administrative Law Judge (ALJ) prioritize agency paid expert witnesses with inferior qualifications over those of a respondents expert witness. Most of the 2022 cases were in California and the government used the same Family Medicine Physician who consults with Pain Management and other medical specialties when necessary. Yet, the ALJ gave more weight to his testimony than to that of an actual expert in Pain Management with decades of clinical experience.

Until this issue is also addressed, clinicians, pharmacists and pharmacy owners and other registrants will not feel it is safe to act in the best interests of patients without putting their CS registrations and livelihood at risk.
