Summary:
In December 2006, the USA regulated sodium permanganate, a chemical essential to the manufacture of cocaine. In March 2007, Mexico closed a chemical company accused of illicitly importing more than 60 tons of pseudoephedrine, a methamphetamine precursor chemical. A new study has found that those events were associated with large, extended reductions in cocaine and methamphetamine users in the USA.

In December 2006, the USA regulated sodium permanganate, a chemical essential to the manufacture of cocaine. In March 2007, Mexico, the USA's primary source for methamphetamine, closed a chemical company accused of illicitly importing more than 60 tons of pseudoephedrine, a methamphetamine precursor chemical. A study published by the scientific journal Addiction found that those two events were associated with large, extended reductions in cocaine users and methamphetamine users in the USA -- impacts that have lasted approximately eight years so far.

After changing little during the early 2000s, cocaine use in the USA began a downward shift at the time of the sodium permanganate regulation. In association with that regulation, there was an estimated decrease of approximately 1.9 million past-year cocaine users (a drop of 32%) and 0.7 million past-month cocaine users (-29%). During the period examined following the sodium permanganate regulation (December 2006 to December 2014), there was little or no recovery in the number of cocaine users.

Methamphetamine use in the USA also began a downward shift at the time of the chemical company closure. In association with Mexico's 03/2007 chemical company closure, there was an estimated decrease of approximately half a million past-year methamphetamine users (-35%), and a decrease of a little more than a quarter million past-month methamphetamine users (-45%). During the period examined following closure of the chemical company (March 2007 to December 2014), methamphetamine user numbers generally remained below pre-closure levels, though a partial recovery in the numbers may have occurred in 2013.

Lead author James Cunningham, PhD, says, "Cocaine and methamphetamine production for international markets requires access to massive amounts of legally manufactured chemicals. Disrupting that access should disrupt the drugs' availability and use." He also says, "Strategies directed towards individual users, for example, information campaigns and direct medical care, have not yet fully addressed the public health problem of cocaine and methamphetamine abuse, indicating the need for additional approaches. To this end, and given our study's findings, control of essential and precursor chemicals warrants a closer look."
