Free meth in Baltimore (if you're an aquatic biofilm)

The fountain of eternal meth has been located in Baltimore, where a study found the drug in local waterways. Plants and animals are even getting addicted, reports Jen Christensen.

It appears aquatic life -- the moss that grows on rocks, the bacteria that live in the water and the bugs that hatch there -- are the unexpected victims of Americans' struggle with drug addiction. ... Drug-addicted water bugs may not be on the top of your regular list of things to worry about, and it doesn't mean you'll be getting high off your tap water any time soon, but the kind of change these scientists saw could be a bigger concern. Here's why: These plants and bugs are the base of the aquatic food web. Birds eat the bugs, as do frogs and fish. As emergent contaminants such as pharmaceuticals and endocrine disruptors become more common in ground and drinking water, they could affect humans. Scientists say the direct health effects are pretty much unknown, and more research will need to be done.
