<em>Federalism </em>is a system of government where individual states unite within an overarching political system, and at the same time allowing the individual states to maintain its own integrity.
This is achieved by requiring that basic laws and policies be made and implemented through negotiation so that all the federating states can share in making and executing decisions.
Mexico practices Federalism because its federating States have the right to make and implement its own unique laws according to the wishes of its indigenous people.
However, there are some some laws which are binding to all the states in the country. One of those laws is that Drug trafficking is an offence nationwide.
