Growing Marijuana is Doing More Damage Than You Think Health/Science

Marijuana is often praised as a healthier option compared to things like alcohol, prescription drugs or even snack foods -- but is it healthy for our environment? Aside from the smoke that’s produced as a byproduct of its consumption, marijuana cultivation and processing requires a LOT of energy, and can produce a considerable amount of pollution in the process.  

What is Marijuana Pollution?

Marijuana pollution is an unsustainable byproduct of marijuana cultivation and is especially troublesome among illegal grow operations. With no regulatory oversight, these grow ops can cause excessive environmental damage including high greenhouse gas emissions, irresponsible water use and dangerous fire hazards.

Many illegal growers prefer indoor cultivation because it is discreet, easy to control and can accommodate multiple grow cycles per year. According to Mother Jones, roughly one-third of America’s marijuana supply is cultivated indoors and the energy needed to power these indoor grow ops is enough to power around 1.7 million homes. As energy is used, greenhouse gases like carbon dioxide and methane are produced at a rate of two pounds of CO2 per joint.

But it’s not only the indoor grow ops that are posing a problem. Throughout the country (especially in California where the weather is favorable) massive illegal grow operations are taking place on private and federally-owned land. Hiding under the canopy of old growth, these outdoor grow ops are difficult to detect which makes regulation and environmental enforcement nearly impossible.

In order to cultivate cannabis successfully in secluded locations, growers must bring in their own nutrients, pesticides and supplies, and will often divert local streams to water the crops. The process requires a considerable amount of land conversion with little to no consideration for the surrounding environment. The consequences can be dire to local wildlife who may ingest toxic pesticides and fertilizers, or who may have their whole habitat removed only to be left in shambles three months later.

Marijuana Production and its Environmental Impact

The Environmental Protection Information Center has outlined some of the most common threats cannabis cultivation poses for the environment in an attempt to educate the public and promote positive, enforceable marijuana reform.

Some of the biggest concerns outlined by EPIC are as follows:

  • Water Resource Abuse

    Many outdoor grow ops do not use public water sources to water their crops. Instead, they often divert water from local streams directly to their crops without storing any for later. This is especially troublesome during the dry season when water is scarce and can adversely affect the salmon population and other forms of wildlife.

  • Trespass grows

    Illegal grow operations that occur on federal land (or on a stranger’s private property) are called trespass grows. These operations are environmentally destructive and often occur in the most environmentally vulnerable locations. Problems with trespass grows are amplified when crop runoff results in fertilizer and pesticide contamination of nearby water sources.

  • Unauthorized Land Conversion

    Without any engineering oversight, many illegal grow ops move an unstable amount of land. Unauthorized grading and land removal can cause a great deal of damage to the environment including soil erosion and threats to local wildlife.

  • “Super Toxic” Rat Poisons

    Many growers use toxic pesticides to protect crops from curious critters. Unfortunately, when small rodents die from ingesting pesticides, their natural predators will also ingest the poison when they eat the rodent. In other words, rat poisons do not just kill rats; they kill other wildlife like bobcats, owls, foxes, coyotes, hawks and even our beloved pets.  

  • Excessive Energy Use

    Both indoor and some off-the-grid outdoor grow operations require supplemental lighting. This requires an excessive amount of energy which may be sourced from local energy companies or produced using diesel-fueled generators. Diesel spills are very common and rarely remedied appropriately.

Solutions to Pot Pollution

In order to reduce the amount of illegal grow operations in America (and the environmental damage they cause), we need to lift the federal ban on marijuana. In doing so, we can closely monitor legal, compliant grow operations to ensure they are meeting protocol without damaging the environment. This will also help reduce the demand for a marijuana black market thus making the risk of illegal cannabis cultivation less enticing.

As long as there is an illegal marijuana market, there will be illegal grow operations to meet demand. These illegal grow ops don’t necessarily account for the damage they cause and therefore often leave a negative impact on the environment.
