Concerning the crime of endangerment with a controlled substance.

HB 1286 makes it a class B felony to knowingly allow a dependent child or adult to be exposed to, ingest, inhale, or touch any controlled substance (including those in Schedules I-IV under Washington or federal law), unless the substance was obtained via a valid medical prescription. This law directly affects caregivers, such as parents or guardians, who may unintentionally or intentionally expose dependents to these substances. The key provision criminalizes exposure without medical authorization, while explicitly allowing legally prescribed medications. Penalties apply to all controlled substances in Schedules I-IV, with no exception for non-prescription use.
