“Medical Cannabis” as a Contested Medicine: Fighting Over Epistemology and Morality

Few empirical studies have explored how different types of knowledge are associated with diverse objectivities and moral economies. Here, we examine these associations through an empirical investigation of the public policy debate in Israel around medical cannabis (MC), which may be termed a contested medicine because its therapeutic effects, while subjectively felt by users, are not generally recognized by the medical profession. Our findings indicate that beneath the MC debate lie deep-seated issues of epistemology, which are entwined with questions of ethics and morality. Whereas some stakeholder groups viewed evidence-based medicine and mechanical objectivity as the only valid knowledge base, others called for recognition of a particular experience-based knowledge, championing regulatory, administrative, or strong objectivity. Stakeholders’ interpretations of what should be considered as ethical courses of (in)action corresponded to their epistemological views, with most criticizing the regulators for relying on regulatory subjectivity instead of objectivity. Our in-depth mapping of this arena allowed us not only to shed light on the emergence of the new entity called “medical cannabis” but also to reexamine the link between epistemology, ethics, and action and to elucidate how heterogeneous groups view the validity and objectivity of knowledge and the interface between medicine, science, and policy.
