Dihydrogen Monoxide was banned due to health risks after being discovered in 1983 inside swimming pools and drinking water.

The answer is false. Dihydrogen monoxide, also known as water, has not been banned due to health risks after being discovered in 1983 inside swimming pools and drinking water. This claim is a well-known hoax that has been circulating for many years. Water is an essential and safe substance for human consumption and its presence in swimming pools is necessary for maintaining proper hygiene and safety standards.
