Stay calm everyone, there's Prozac in the drinking water

"It should make us happy, but environmentalists are deeply alarmed: Prozac, the anti-depression drug, is being taken in such large quantities that it can now be found in Britain's drinking water. Environmentalists are calling for an urgent investigation into the revelations, describing the build-up of the antidepressant as 'hidden mass medication'. The Environment Agency has revealed that Prozac is building up both in river systems and groundwater used for drinking supplies."
