Things that go "POP" in the night! - really scarry!

I have seened advertisments comparing Coke-a-cola to Marijuana and asking which is more dangerous (The cola of course) This sounds like a good reason to stop supporting a company that wishes to buy up all the water so they can charge 12.80 per gallon for it (The price for their brand of bottled water 3 miles from where I'm sitting) and switch to water from a filter pitcher like a PUR or a Britta. Which is likely better beside. (What I drink).
