It is the intent of the legislature to provide the opportunity for terminally ill patients to have access to certain investigational treatments without requiring another party, including a physician, manufacturer, insurer or government agency, to offer, provide or pay for such treatments. By enacting this chapter, the legislature intends only to permit these treatments to terminally ill patients in Idaho. It is not the intent of the legislature to create an obligation but to ensure that all persons or parties availing themselves of this chapter do so voluntarily. Due to the experimental nature of these treatments, it is further the intent of the legislature to protect physicians and other parties from civil, criminal or professional liability relating to the treatments.
