In 2005, levamisole was found in almost 2 percent of the cocaine seized by the DEA. In 2007, the frequency went up to 15 percent, and by 2011 a staggering 73 percent of all cocaine seized by the DEA had been cut with levamisole. The same tendency is seen in Europe and in the samples I have analyzed myself. From 2008 to 2009, the frequency was around 66 percent, and from 2011 to 2012 it had gone up to 90 percent in Danish cocaine.
