Your drinking water has drugs in it
Many studies have found pharmaceutical drugs in tap water. Usually small amounts so feel relieved at that, but it builds up. This is usually from human waste from humans taking drugs contaminating the water supply. And in some cases governments purposefully add drugs like antidepressants into the water supply to 'help with mental illness' which is their way of saying mind control the population.
