i guess you could "overdose" on water by drinking too much and drowning in it, ive heard rumors of people doing that, but im not sure how true that is.
if you look at death as the ultimate sobriety, which seems to be the case, then yea, water could be looked at as a drug keeping our spirits imprisoned in these bodies. but the word "drug" has a variety of definitions, most of which i dont agree with. i probably wouldnt go so far as to categorize it with entheogens. water keeps us here physically, while entheogens take us as far out as possible spiritually, giving us insight of true freedom.
i guess it doesnt really matter though, all of the recycled city water contains insane amounts of antibiotics, anti-convulsants, mood stabilizers and sex hormones to name a few!
what brought about this idea?
There is no such thing as a fact, only the subjective opinions of others.
