Well. That article is right and wrong. The government is going to put small GPS tags on some medications (oxycodone, paxil, and ambien) so that they can be tracked from the manufacturer to the distributor. A great, great number of those pills go "missing" between those two points. Think of this as quality control. Once the pills come out of the original packaging and into your prescription bottle, they will no longer be "tracked". TIME magazine had a very large article about this a few weeks ago.
