Are California’s Medical Weed Farms Hurting The Environment?

Not so green after all?

by Whitney Allen

In California’s Emerald Triangle, the nation’s largest area for growing medical marijuana, federal anti-drug laws are keeping the state from regulating the growing industry. A California state law passed in 1996 that decriminalized the use of medical marijuana has led to an influx of dispensaries and pot farms to service them. The marijuana industry is now growing unchecked by state officials because of pressure from the federal government on would-be regulators.

Maggie Caldwell from Mother Jones describes the situation:

The farming of marijuana—for medicinal use or otherwise—remains illegal under federal law. Any regulation instituted by these agencies is, in effect, legitimizing the cultivation of a federally controlled substance, and the US Department of Justice has warned local officials that they could face individual prosecution if they continue to validate the farms. Mark Lovelace, a Humboldt County supervisor, says the DOJ’s policy is actually abetting the weed farmers, allowing them to get away with unchecked land development.

This comes at a time when federal action has brought “renewed chaos” to California’s marijuana industry. The IRS and DEA punish dispensaries indiscriminately, giving advantage to those who can operate under less ethical means. The combined effect of these raids and local authorities’ inability to regulate has pushed some who want to operate ethically out of the market, clearing the path for drug cartels to set up huge operations in the region.

This inaction is spelling disaster for the region around the Emerald Triangle. Without state-level guidelines and enforcement, farms are implicitly being allowed to institute practices that are harmful to the local environment, as well as potentially dangerous for the end user.

Land clearing for marijuana growth has threatened the habitats of animals such as the spotted owl, classified as “threatened” by the Endangered Species Act. A great deal of this clearing has been done on public lands, which is illegal in the state and not protected by its medical marijuana laws. Authorities anticipate finding over a million marijuana plants growing on public lands in California this season alone. The problem has reportedly gotten so out of hand that authorities are using planes and high-resolution cameras to find cleared lands used for illegal farming.

Water and pesticide use is also threatening the local fish population. Several cases of illegal damming and stream diverting have been reported. Those convicted are granted only misdemeanor charges. This is all occurring in an area that has spent millions of dollars attempting to bring the coho Salmon back from extinction.

Even some of America’s most treasured national parks are not safe. A case in September indicted marijuana growers in the Sequoia National Forest who were using extremely toxic pesticides, the active ingredient of which is so potent that “a quarter teaspoon of it can be fatal to humans.” The damage from these grows can have lasting consequences and rely on taxpayer money to be cleaned up. In addition, there are potential health threats to patients, since it is virtually impossible to know for sure how the marijuana is grown and what substances were used to cultivate the crop.

Advocacy groups like the Emerald Growers Association say that sustainable, environmentally-conscious marijuana cultivation is possible and have recommended grower guidelines, which include Integrated Fertilizer and Irrigation Management and the collection of rainwater. For now, in the absence of any real regulatory force, the industry must rely on self-regulation.

    Legalize it 100%, already!

    Colorado has had legalized use for medical purposes for some time and just passed a bill legalizing it for recreational use (not in public, though, though one has been able to get high riding the gonodolas at all the major ski areas for years and that’s w/o even lighting up). Washington, too. This is what we need to do on all the states to get that damn Mexican cartel out of here.

    The worst environmental damage comes from indoor growing and the many kilowatts of fossil fueled electricity. Maybe a ton of carbon emissions for one pound of dope.

    There’s no easier plant to grow in your backyard, yet this whole horror show goes on and on. Why? Well I know the answer, but won’t bore you with the dreadful truth.

  6. Mulga Mumblebrain says:

    Do you ‘septics’ call someone who doesn’t pass the joint around quickly enough a ‘Bogart’ as we do (or used to) down here?

  7. prokaryotes says:

    No, no … go on :)

    It’s OK to spend millions trying to change peoples’ minds by using every linguistic and visual trick in the trade but people can’t change their own minds with a plant, ME

    The criminalisation of drugs serves several purposes. First the huge black market mobilises billions in black money, that is laundered by the big banks for huge profits. The money is used to suborn politics throughout the poor world and by Western intelligence agencies (the CIA to the fore) as a source of secret unaccountable funding. Accusations of involvement in drug trafficking are useful as an excuse to subvert non-compliant regimes, while compliant narco-states are granted immunity from intervention. And the hysteria over drug use and the petty crime required to service a habit is useful as part of the ‘strategy of tension’ where societies are kept in a state of heightened anxiety and paranoia, which the Right sees as politically advantageous to them. Moreover the surveillance techniques justified by the never-ending ‘War on Drugs’ will come in useful when there is a real revolt by the rabble. There you have it, and, of course, I will now have to go deeper underground having blabbed too much.

    We need to decriminalize Cannabis.

  11. Gary says:

    MMJ growers should all be using organics, regulations should mandate it, problem solved.

    Also, marihuana acts as an alcohol substitute. It probably does the same for tobacco also. I am sure both these industries have highly vested interests in preventing its legalization.

    I think it’s time we start legalizing Marijuana everywhere. Stop living in fear and start thinking about how great the future will be! LEGALIZE IT!

    Why don’t we just start legalizing it everywhere? Why are so many people still stuck in this FEAR stage…? Stop worrying, start hoping. LEGALIZE IT!

    If you live in a state where Marijuana isn’t legal yet and still want the same type of highs, I suggest checking out It has amazingly detailed legal highs reviews and where to get them without getting ripped off!
    Also! I’m starting up a new forum dedicated to my fellows stoners. Come on over and join the high conversations! We’re quite new, but VERY welcoming.
