Ladies, are you still flushing your used tampons? Because if so, just know that you are contributing to a huge problem.

According to the Guardian, half of all women in the UK are still flushing their tampons, unknowingly (or knowingly, those monsters!) causing drain blockages that can lead to floods and pricey removals.

It costs approximately $114.2 million a year to unblock drains in the UK, and that price is reflected in water bills. Not to mention, it results in environmental pollution ("sewage-related" debris comprises about six percent of the beach refuse in England).
