California’s Campaign Against Marijuana Planting (CAMP) reported 4,320,314 plant seizures in the 2010 season, slightly less than the all-time record of 4,463,917 set in 2009.[1][2] CAMP estimated the destroyed crop’s wholesale value at $17.2 billion, working out to $4,000 per plant and over a pound per plant.[1][2]

At that rate the marijuana destroyed amounted to more than four times California’s estimated annual consumption of one million pounds a year, and CAMP’s haul had grown tenfold since 2002-2003.[1][2] The leading counties were Mendocino with 572,680 plants, Tuolumne with 411,004, Lake with 374,958, Shasta with 325,480 and Tehama with 312,574.[1][2]
