Legal Question in Family Law in Washington

If there are no court orders in place, then yes, on an emergency basis, the father can leave with the children, to protect himself and the children. I would suggest then consulting with an attorney to find out what can be done. More facts are needed. For example, are the mother and father married? What, if any court orders are now in place? What led to the Adderall prescription abuse?

Does the father have a history of substance abuse or domestic violence? If so, he needs to be careful how he proceeds, since that will all be brought up against him, if court action is needed and he needs a plan to address it.

An even bigger question that needs to be addressed is what can be done to get the mother help, if the father is merely looking to get the kids to safety followed by figuring out how to restore the mother's mental health. Again, this requires a consult with an attorney. The money you spend to at least consult on the matter will be well spent to know your full rights.
