Using the law of conservation of matter and extending your own logic, matter (mass) can never be created or destroyed, only transformed, so weapons of mass destruction don't exist.

Mass reduction

Deciding if this belongs here or in Dad's jokes 🧐

Nope. They don't destroy the mass, just move it away from your body

Fun fact, most of the weight you lose is exhaled through your lungs :3

They’re weapons of ass reduction

The "mass" in "mass destruction" is referring to the quantity of the destruction, not what is being destroyed.

The definition of mass being used in this context is an "a large quantity, amount, or number"

Think of it like, "massive destruction"

So, you'd have to be thinking of an amount of weight loss beyond what anyone has seen before.

Another question, should we be using weight loss drugs when we're already concerned about the amount of carbon being released into the atmosphere?

Ridiculous. This would violate the law of conservation of mass. WMDs are not physically possible.

Weapon of mass reduction.

noooo noooo

WMD's are in the middle east only
