Large marijuana grows dangerous to environment & humans

Posted: Updated:

KENNEWICK, Wash.--  The Department of Justice is warning against the dangers of large marijuana grows.   They're not just illegal, but can also harm the environment and people around them.

James McDevitt, U.S. Attorney for the Eastern District of Washington, says right now is harvest season for illegal marijuana grows.  Many have already been busted such as one huge grow in Walla Walla county where authorities found nearly 35,000 pot plants, or another one near White Swan where 1,700 were found.

McDevitt says these grows are a major environmental hazard.  He explains, "They cause significant degradation to the environment with their illegal campsites, pesticides, fertilizers, trash, human waste, and thousands of feet of PVC pipe and hoses." He says the chemicals can seep into the ground or into water sources.

Another danger is armed guards who keep watch over the crop.  McDevitt says they're likely to do anything to defend their grow. So, if you're out hunting or hiking and see a marijuana grow, leave as quietly as you can, and call 911 as soon as you're away from the area.
