Q: Does the herbicide glyphosate cause cancer?
A: There is evidence to suggest it may cause cancer at very high doses, but not at the low doses typically found in foods.
Q: Have scientists confirmed that e-cigarettes cause an incurable respiratory disease called “popcorn lung”?
A: No. The vapor of some e-cigarettes contains a chemical associated with popcorn lung, and a case report suggests a possible link. But there’s not enough evidence to conclude the vapors cause the disease.
