I do agree there is a partly ethical issue in clinical trials because people can endure harsh side effects from the product they are testing. However, in clinical trials scientist do not force people to test the product it is the tester decision if they want to risk their life in testing product. In order for future generation to prosper we have to want make sacrifices for them to achieve a better life. There is a lot that can happen during the trial but there is a document that is signed by the tester that they must understand all the warning side effects and give consent before starting the trial. People can die but they give consent and should have understand what they committed to.
