Consumer Lawsuit Over Pesticides On Marijuana Would Be First In Nation

Pesticides are used on tobacco and food a lot. According to scientists, there is a threshold for pesticide ingestion where below certain levels is harmless, and above certain levels is considered to be a hazard to your health. Pesticides are commonly used when growing marijuana, but there are not any studies or scientifically proven limits as to how much pesticides is too much on marijuana, and what pesticides should be avoided altogether. It’s something that states have been struggling with as they see their medical and/or recreational marijuana industries grow.

Pesticide use in Colorado has resulted in what is being described as a ‘first-of-its-kind’ lawsuit. Per US News:

Two marijuana users in Colorado filed a lawsuit Monday against a pot business they said used an unhealthy pesticide to grow their weed — a case that lawyers say is the first product liability claim in the nation involving the legal marijuana industry.

The case underscores disagreement over what chemicals should be allowed in the cultivation of pot and leaves the plaintiffs facing a dilemma: The U.S. government still regards almost all marijuana as an illicit drug and there are no federal safety guidelines for growing it.

The state of Colorado has approved a list of pesticides that are acceptable to grow pot, but it’s far from complete and leaves out several pesticides that are commonly used on both food and tobacco.

The lawsuit filed in state court targets use of a fungicide called Eagle 20 EW by a Denver-based pot company called LivWell, where authorities quarantined thousands of plants earlier this year, saying they had been treated with the pesticide.

There have been some very eye-opening articles lately in regards to pesticides and legal marijuana. Investigative reports have found very high levels of pesticides on plants, which has led to calls for more comprehensive pesticide rules. Something that I have talked about with people before, but seems to have not gained any traction (yet), is the use of heavy metal fertilizers during the grow process. Even the tobacco industry regulates heavy metals. The marijuana industry needs to get out ahead of things, and not be like the tobacco industry and try to ignore things until the industry is forced to make changes.

  1. Saw it too, it mentioned problems when growing a monoculture and its downfalls and the use of AACT to control disease and insects, AACT was pioneered by DR. Elaine Ingham. This person knew what they were talking about, why the post was deleted is baffling. Please explain oh mighty gods of censorship here at Weed blog

  2. Phuck the losers that run this joke of a website for deleting useful information that said nothing bad about anyone. I will not visit anymore

    There was a removed post from a member that I will give a reply to, in any case. Growing ones own supply is always best, but it is irresponsible for the average grower to allow molds and fungi to go untreated as, outside of a university style greenhouse, these molds and fungi are airborne and can affect any other crop or plant life within a quite large area. I have stated my former connection to Humboldt County Growers at the beginning of custom hybrids within cannabis at the early 1980’s timeframe. Those I traded with came to the Midwest in groups and they examined each plant they took for breeding experiments. They checked the seed containing colas for any sign of mold and disease as well as the stalks, side branches, and the roots for any sign of disease, mold, or insects (there are common places to check for insects and egg deposits. It was worth their quality seeds and cash they provided, to boot, to go through this professional procedure. Soap sprays and a tobacco tea (made using menthol chewing tobacco, or a pack of menthol cigarettes, cut the foot off a pair of pantyhose, then place four good pinches of chew, or about 5 cigarettes in the pantyhose foot toe area, then you brew a “sun tea” at room temperature using the tobacco, remove the sock when it appears to be a weakly made tea and transfer what you have made into a spray bottle and lightly mist the plants). I learned most all of my everyday item organic tricks from the Oglala Sioux when I spent the summer with my American Indian friends. If the plants do not get these substances “rained off” then give them a good garden hose shower set on mist and give them a good soaking. Do this before the flowers show signs of maturing and setting on trichomes, or you could lose some potency as the THC producing nodes form on the fragile trichomes and a rain can knock these important plant parts off, especially if you hit them with a full spray, or a hard rain. As terpenes are natural insect and fungi repellants and killers, respectively, I look forward to the day when we have enough excess cannabis to specifically remove the major terpenoids responsible for fungi, mold, and insect repellant and fungi/mold killers making use of the plant’s natural ingredients to kill molds and fungi and repel insects!!!

    It is sad to see the use of chemicals in the growth of cannabis. Cannabis has natural pesticides within the terpenes, in fact, one of the present natural pesticides has been studied in rodents that survive only on a plant where this terpenoid is far stronger. There were no ill effects found in the Southwest Desert Rat that eat this terpenoid containing plant exclusively. They were found to be in very good health (even without cannabis). This so surprised scientists that they brought the species of Arborvita to the lab and force fed lab rats, where the results were the same. Cannabis is truly an amazing plant that will seed itself and thrive even where it was not expected to, the Northern Midwest. Not only did cannabis adapt and thrive here, the only loss was potency as it became a landrace strain along the railroads that seeded it for fibers during WWII. It was of no use to us, but the Humboldt County growers found it most interesting. They began crossing what we considered “ditch weed” that only gave anyone stupid enough to smoke it a pretty healthy headache. I traded guaranteed unsprayed and pesticide free reverted cannabis to Californian breeders in the early ’80s and today, when I see a strain that has the side effect of mild to moderate headache; I cannot help but wonder, did I once trade the genetics for this strain to my Cali friends? I got a wide range of imported seeds and one, in particular (a cross of a Nepalese Temple Ball strain with a Northern India Mountain Indica), which became known in my small community as “the seizure stopping weed!!!” I would love to reproduce this girl as it did what everyone was happily shocked to see, it stopped seizures in a friend who became brain injured at work in Huston, TX. His seizures went all but extinct, but prior to this strain they occurred several times a week lasting 30 to 45 minutes!
    The reverted cannabis we had was never tended, nor was it ever treated, but there it grew just as healthy and pest free as any GMO. They also produced some very high yields as the buds were HUGE. I had my hands pictured in “High Times” holding an almost 18″ long and eight and one half inch circumference bud of what I began to recognize as having strong indica characteristics!!! The railroad didn’t seed hemp in 1942, they seeded sativas and indicas that simply lost what little potency it had over the 40 years of self seeding. I do not fault Denver grows, I formerly worked at a garden and pet franchise and we got commissions on all chemical options we sold. So, their pesticides were likely earning some supplier a huge commission check. I knew my cannabis gardeners, as only another grower would recognize the customer for certain supplies, in large quantity, that only the serious cannabis grower would need. I pointed them to soap based pesticides and often had them mix a weak tea of chewing tobacco juice to lightly spray on their plants. None of these components poison the plant, but your plants will need a good shower before full flower development. That is when your plants will begin strongly releasing terpenes that will keep the nasties away. I do not remember one instance of pest problems (which are easily visible) on the Midwest ditch weed. I saw patches survive and flower after 2,4,D application and even the 1980’s formulation of Round-Up!!! We could only kill them out in areas using diesel fuel, but this also killed the soils ability to generate even a blade of grass!!!

  5. Sad to see this suit for many reasons including medically and politically. But perhaps it was inevitable since who was going to sue underground pot dealers? While consumers can buy organic grapes, Cannabis can’t be labelled “organic” because pot remains federally illegal.

    What must a consumer do who must use dispensaries but also wants organic weed? One option seems to be a new (to me anyway) third-party certification for Cannabis similar to the “organic” label, called “Clean-Green” certification – See: http://cleangreencert.com/home/. In Portland the dispensary, Calyxes.com , is featuring this. Perhaps some label like this can protect consumers until “organic” practices become standard and we get organic labels like other agriculture products.

  6. Many growers encourage pest and molds and fungus by using a monoculture of genetics, at least that has been the case in Humboldt. Stress pressuring and using only those plants which show a resistance to mold, insects and fungus is the solution. Also using all organic AACT teas as foliar sprays has yielded great results for me. I am very disturbed my the plethora of chemicals sprayed on indoor and outdoor
    crops here in Humboldt

  7. Are indoor gardens that much harder to keep pest free? My outdoor plants have not needed a single thing for pest control. Then again, I was a regular home gardener for years before I was able to legally cultivate, so maybe my yard full of good bugs kept most of the bad ones at bay.
