The origin, creation and application of the concept of Federalism relative to U.S. system of government The concept of federalism has played a fundamental role in shaping the structure and functioning of the United States government. Federalism, as a system of governance, divides sovereignty between a national (federal) government and various regional (state) governments, allowing for a balance of power that aims to promote governance, protect rights, and accommodate diverse regional interests (Kincaid, 2018). The origin of federalism in the United States can be traced back to the country's founding principles, specifically the U.S. Constitution drafted in 1787, which sought to create a stronger central government while maintaining the independence of individual states (Elazar, 2019). This delicate balance was a response to the weaknesses of the Articles of Confederation, which had limited the powers of the federal government and resulted in a fragile union among states. The creation of federalism was further reinforced through the specific enumerations of powers granted to the federal government and the reserved powers retained by the states. The Tenth Amendment explicitly stipulates that powers not delegated to the federal government are reserved for the states or the people, embodying the dual sovereignty that defines American federalism (Hofstadter, 2020). The application of federalism in the U.S. legal system manifests through the division of authority across various levels of government, each with distinct yet overlapping competencies. Federalism thus facilitates both national unity and regional diversity, allowing states to serve as laboratories for policy innovation, while the federal government provides overarching national standards. Legal conflicts: Federal law prohibiting marijuana versus state laws sanctioning its use One of the most prominent examples of the complexities within the U.S. federal system involves the legal status of marijuana. Under federal law, specifically the Controlled Substances Act (CSA) of 1970, marijuana is classified as a Schedule I drug, indicating high potential for abuse and no recognized medical use (Drug Enforcement Administration [DEA], 2020). This classification renders the possession, sale, and distribution of marijuana illegal under federal statutes. However, despite this federal prohibition, numerous states have enacted laws legalizing marijuana for medical and recreational use, creating a significant legal conflict that exemplifies the tensions inherent in federalism. States such as California, Colorado, and Oregon have implemented policies permitting the regulated use of marijuana, either for medical purposes or recreational consumption. These laws are viewed by many as an exercise of state sovereignty, intended to reflect the preferences of their residents and manage local issues
