House Bill 1888 amends and adds sections to chapter 18.36A RCW and amends other statutes to expand the scope of practice for naturopathic physicians. The bill explicitly includes within naturopathic practice the prescription, administration, dispensing, and use of legend drugs and controlled substances in Schedules III–V and stimulant medications in Schedule II, and it creates a new statutory section permitting naturopathic physicians to prescribe and administer those drugs subject to requirements. Before prescribing controlled substances other than testosterone and codeine products, a naturopathic physician must pass a board‑approved pharmaceutical prescribing examination and register with the prescription monitoring program; the board of naturopathy must adopt any additional education and training requirements by rule. The bill also authorizes naturopathic physicians to sign and attest to medical and legal forms within their scope of practice and amends RCW 69.41.030 to list naturopathic physicians among practitioners whose prescriptions lawfully allow sale, delivery, possession, or use of legend drugs. The bill also amends RCW 69.50.101 and related controlled‑substance and cannabis definitions and exceptions. It restates many statutory definitions (for example, practitioner, narcotic drug, opiate, THC concentration, cannabis products, manufacture/production terms) and identifies which professionals qualify as practitioners for controlled‑substance purposes, expressly including naturopathic physicians. The amendments and related sections list exceptions to prohibitions for various licensed practitioners and entities, set criminal penalties (sale/delivery/possession with intent to sell is a class B felony; knowing possession and knowing use in a public place are misdemeanors), and encourage diversion and referral to treatment or services in lieu of prosecution or booking for certain possession or public‑use offenses. The text also defines a "social equity plan" for cannabis licensing and authorizes a licensing board to approve plan components after consulting a task force. Several portions of the bill text are not included in the extracted material. The remainder of the amended RCW 69.41.030 list is incomplete, the full amended text of RCW 69.50.101 is not provided here, the statutory definition of "manufacture" is cut off, and the specific content of the board‑approved examination and any rulemaking details for additional education and training are not present in the excerpts.

If enacted, licensed naturopathic physicians would be able to prescribe, administer, and dispense a wider range of medicines including legend drugs, controlled substances in Schedules III–V, and certain Schedule II stimulants, and could sign physician-type forms (for example disability or hospice forms) when those acts fall within their scope. Practitioners who want to prescribe controlled substances other than testosterone and codeine products would need to pass a board-approved prescribing exam and register with the state prescription monitoring program, and the naturopathy board must set further education and training rules; this will increase training and administrative requirements and likely impose time and cost burdens on naturopathic physicians to qualify. The board of naturopathy, the department of health, and the prescription monitoring program would see more regulatory work—rulemaking, oversight, and additional registrants—and the governor is asked to appoint or the board to consult with a naturopath experienced in controlled-substance prescribing. Expanding prescriptive authority may increase access to primary care medicines for patients but also raises oversight and diversion risk that the new exam, training rules, and monitoring aim to mitigate. Key implementation details (the exam content, the board’s specific training requirements, and the remainder of statutory amendments) are not included in the provided facts.
