No medicine can be sold unless it has first been approved by the U.S. Food and Drug Administration (FDA). The manufacturers of the medication perform tests on all new medicines and send the results to the FDA. The FDA allows new medicines to be used only if they work and if they are safe enough. When a medicine's benefits outweigh its known risks, the FDA usually approves the sale of the drug. The FDA can withdraw a medication from the market at any time if it later is found to cause harmful side effects.
List of indigenous people of the Americas. This is a list of notable indigenous peoples of the Americas. This list includes Inuit people, Yupik peoples, Aleut people, Alaskan Natives, Native Americans, First Nations, MÃ©tis, Indigenous Mexicans, the Caribbean, Central America, and South America.
Indigenous communities, peoples, and nations are those that, having a historical continuity with pre-invasion and pre-colonial societies that developed on their territories, consider themselves distinct from other sectors of the societies now prevailing in those territories, or parts of them. defining characteristic for an indigenous group is that it has preserved traditional ways of living, such as present or historical reliance upon subsistence-based production (based on pastoral, horticultural and/or hunting and gathering techniques), and a predominantly non-urbanized society.
