According to the DEA’s Domestic Cannabis Eradication/Suppression Statistical Report, agents eradicated 4.25 million marijuana plants nationwide in 2015. That total is slightly less than the total reported by the agency for the year 2014 (4.3 million) and continues to the ongoing decline in eradication totals since 2010, when the agency reported eliminating some 10.3 million plants.
As in past years, DEA eradication efforts largely focused on California. Of the total number of plants seized nationwide by the DEA in 2015, 62 percent were in California.
Only about 7 percent of all plants seized by the DEA were from indoor grows.
The DEA reported making some 6,300 arrests in conjunction with their cannabis eradication efforts — a total that mirrors 2014 figures. By contrast, the agency reported making nearly 10,000 marijuana arrests in 2010 and 8,500 arrests in 2011.
