Methamphetamine production continues in small laboratories in Tennessee and elsewhere around the country in spite of new laws regulating and tracking the sale of pharmacy products used to manufacture the illegal drug.
That is one of the findings of a report released this week by the Comptroller’s Offices of Research and Education Accountability about attempts to control access to legal products sold at pharmacies which are later used to create methamphetamine.
Pseudoephedrine, the most common of the so-called “precursor” products used in manufacturing the drug, is an ingredient in many over-the-counter cold and allergy remedies.
The report cautions that the relatively short history of precursor control policies and the limitations of available crime and drug use data make it difficult to draw conclusions about the effectiveness of particular precursor control laws on the production of methamphetamine in small labs.
In 2011, the Tennessee General Assembly passed legislation to implement a real-time, electronic tracking system — the National Precursor Log Exchange (NPLEx) — to limit the quantities of precursor products that can be purchased by individuals.
After much debate, NPLEx was chosen over a more restrictive requirement that people obtain prescriptions from doctors for the pharmacy precursors.
The 2011 legislation included a directive for the Comptroller’s office to conduct a study and issue a report.
That report, called “Methamphetamine Production in Tennessee,” shows activity in small labs is prevalent in Tennessee and some other southern and mid-western states despite implementation of pharmacy precursor sales limitations and enhanced tracking systems. Law enforcement officials in Tennessee and nationally attribute the increase in methamphetamine lab incidents to the ability of producers to work around precursor control policies.
Three areas that have implemented prescription-only policies for methamphetamine precursors — Oregon, Mississippi and some parts of Missouri — have seen decreases in methamphetamine lab incidents.
However, two studies of the 2006 Oregon policy question the extent to which other factors may have contributed to the decline, since other western states also had similar declines.
Mississippi and parts of Missouri, which were both high methamphetamine production areas in 2009 like Tennessee, saw a reduction in methamphetamine lab incidents in 2010.
Law enforcement officials attribute the decline to the change to a prescription-only policy.
Other nearby states without prescription-only policies did not see declines in 2010.
Approximately 10 percent of adult Tennesseans purchased pharmacy precursors to methamphetamine from January through June 2012.
The report emphasizes that precursor control policies focus on preventing or reducing local methamphetamine production, not methamphetamine use.
A decrease in the supply of locally-produced methamphetamine may not necessarily result in a reduction in methamphetamine use.
Most of the methamphetamine available in many parts of the United States is supplied by Mexican criminal organizations and is produced in foreign and domestic super labs.
