Drug-enforcement officials in Washington said they destroyed more than 130,000 marijuana plants in 2006 as part of a joint state and federal eradication effort.[1] That was nearly the same as the year before, when a record 135,000 plants were destroyed under the Washington Domestic Cannabis Eradication/Suppression Program, the Drug Enforcement Administration said in a news release.[1]

The 2006 seizures led to more than 340 arrests and 190 weapons seizures.[1] Officials attributed the number of destroyed plants to the movement of drug traffickers from Canada to Washington in an effort to avoid tightened border security.[1] “Washington state is susceptible to both outdoor marijuana growers, who typically use and damage public lands to ply their illegal trade, and previously Canadian-based indoor cultivators attempting to avoid cross-border detection,” said DEA special agent in charge Rodney Benson.[1]

Agents said growers had dammed streams, clear-cut forest lands, used large quantities of insecticide and killed wildlife to aid the outdoor growing operations.[1]
