Creates registry of individuals who required medical assistance as result of misusing controlled dangerous substance.

S 2451 creates a confidential registry for individuals who received medical assistance due to misusing controlled substances (like opioids). Hospitals, emergency responders, and police would submit this data to the Commissioner of Human Services, who would make the registry accessible to healthcare providers. Providers would be required to check the registry before prescribing any controlled substance. The registry is protected by privacy laws, and the Commissioner must report annually to the Governor and Legislature. This directly affects healthcare practitioners prescribing controlled substances and individuals with substance misuse medical incidents.
