: The right to access to drug is not specified as an independent right in the international documents; and has been considered in the area of health, as one of the equipment of being healthy. Right to physical and mental health has been described and recognized absolutely as a foundational right in the international humanitarian rights documents. In this research, we studied the right to health and access to drug from the viewpoints of international human rights and humanitarian rights, and Iran provisions. METHODS: In this descriptive-analytic research, some of international documents about human rights and humanitarian rights, as well as some provisions of Iran and some related cases were studied using library research tools. FINDINGS: The importance of attention to right access to drug as a fundamental human right was emphasized in international and Iran documents. CONCLUSION: As the right access to drug is considered as a fundamental human right, it seems that a specific international covenant should be codified on this issue by the United Nation and other international competent organizations.
