Emerging drugs tracking system
The U.S. federal government will be implementing a tracking system for identifying new drugs. It will be limited to Washington, D.C. and certain parts of the state of Virginia, but hopefully will spread further. The only weakness I see is that the urine samples will come from individuals involved in the criminal justice system, which represents a specific population that may not be disposed to use new drugs. For the most part, people in the criminal justice system tend to use cocaine, heroin, cannabis and alcohol.
