Snorting Shrimp?

Over at Dustbury, Charles notes how researchers looking for micropollutants in English water wildlife found it, but represented in some unforeseen ways.

To wit, they found things like cocaine in the shrimp. It was just trace amounts, leaving the puzzle of how to make a "Say hello to my little frien'" joke about hundreds of miniature Tony Montana's White Powder Mountains as yet unsolved.

Scientists theorize that the shrimp ingest the cocaine, as well as the other drugs they found, when those drugs are dumped down toilets or off of bridges in order to prevent seizure by police. Or simply because it's the easiest, if not best, way to dispose of old legal drugs as well. Which makes a lot more sense than figuring out how the shrimp cut a line on a mirror while underwater, let alone how they snort the stuff not having nostrils and all.
