Unethical human experimentation in the United States

Unethical human experimentation in the United States is when researchers try out dangerous or harmful things on people without the person’s full understanding or consent. An example is when scientists give people medicines or do tests without telling them it could be dangerous. This can hurt the people and is not nice. In the United States, it is against the law to do such experiments, but sometimes people do them anyway.
