Common Pot Test Flawed

Looks like a commonly used test to screen for the presence of marijuana is being accepted more and more as positive proof something is marijuana. Problem is, the test can be subject to false positives, according to John Kelly. People are being prosecuted, if not convicted, as a result. It looks like more and more courts and law enforcement agencies are accepting its use as positive proof of possession, as well.

I'm not suggesting that every piece of marijuana confiscated by police need be subjected to the more lengthy and expensive testing, but if you end up in the same situation as the girl cited at the beginning of the story, you most certainly should demand the gas chromatography test.

Hat tip to Radley Balko, over at The Agitator blog for the heads up.
