The same government agencies and scientists have repeatedly denied the existence of chemical trails.

The [[United States Air Force|US Air Force]] has argued that the theory is a hoax, a view which is recognized by many universities, scientific organizations, and the [[mainstream media]]. The Department for Environment, Food and Rural Affairs (a British regulatory agency) stressed that the "chemical trails" theory is unscientific. A Canadian parliamentary leader said that "chemical trails" is just a popular expression and that there is no evidence supporting their existence. Similar responses were given by various Italian governmental figures as well as by pilots and weather experts. Magazines and programs have established this scientific theory as a hoax.
