The role of pharmacologist is to investigate drugs and chemicals that are used unsafe. They have to understand how chemicals interacts with the human body. Pharmacologists wanted to gain a deeper understanding of disease and develop new drugs to treat them and promote the safe use of existing drugs. The U.S. Food and Drug Administration (FDA) is part of the U.S. government that makes sure foods and medicines are safe. The FDA has examined these e-cigarettes and informed that half contained toxic chemicals. They also found out many of e-cigarettes contained nicotine, which are found in regular cigarettes. I believe that e-cigarettes should be banned because of health problems.
