Can an Oklahoma Grower throw away Bad Plants?

The Oklahoma medical marijuana industry began in the fall of 2018, and as of this writing, is soaring every month in terms of sales and business activity. The number of consumers as well as the number of businesses continue to grow every quarter.

And with a growing industry, comes increasing government regulation, which then causes confusion (and sometimes anxiety and fear) among the small business owner who makes a living in this new cannabis economy.

This article will tackle one of the latest issues that Oklahoma cannabis growers are struggling with, and that is the issue of marijuana waste disposal.

Those who are involved in the business of commercial cannabis cultivation know that the business involves a lot of waste. For those who are unfamiliar with how large-scale grows operate, allow me to illustrate what we are talking about.

Why is there so much waste in Cannabis Cultivation?

In both indoor and outdoor grow operations, the operator is overseeing hundreds of plants, through all stages of the life cycle, which can be several months. Let’s illustrate further what it looks like in an indoor grow facility.

The grower starts with seeds. The grower plants many seeds, knowing that not all seeds will sprout. The grower plants 10 seeds, and only 4 sprout. Right there we have our first encounter with waste.

Next, the grower takes the seeds that have sprouted and puts them into a small container with soil (indoor growers usually “pop” seeds in water or small containers without soil).

The grower monitors these fragile little babies, hoping they will survive and something green with rise from the dirt. Once a green leaf has popped, we now have a plant. An incredibly fragile little plant.

The grower monitors these little seedlings, nudging them into growing into stable plants. But often times, these little guys die. Waste.

The plants that survive then grow from a tiny little seedling into something that actually resembles a plant. Now it’s time to transplant these seedlings into a larger container/pot with more soil, so the roots can grow and expand. Transplanting is stressful so. Stress increases the chances things will go wrong, and even die. Possibly more waste.

Now the plants are growing in their vegetative state. They are growing fast. They need to be pruned. The iconic weed leaf you’ve seen does not yield flower (bud). It is simply there to absorb light for photosynthesis. And your typical pot plant has a lot of fan leaves.

The grower knows what to do to maximize yield: trim off the fan leaves, and even the bottom branches that are less likely to receive a lot of light and focus on the top colas that will yield the bigger buds. Trim off the bottom half, focus on the top half. Waste.

Therefore, a primary task in cannabis cultivation is trimming. Which means lots and lots of waste.

Also, during the vegetative stage, the grower is cloning plants so that he/she does not have to resort to planting seeds again. Cloning means snipping a branch that has a “top” on it, and then planting that branch in a separate pot. If it survives, it will become a new cannabis plant. So another part of the business is maintaining a regular cloning schedule, such as cutting new clones bi-weekly. But not all clones survive. More waste.

There are two stages of photo-period cannabis plants:

  • vegetative stage, and
  • flowering stage.

Up until now, we’ve been discussing the vegetative state, where the plants are receiving more light than darkness (which mimics the summer months), and keeps the plants growing, but not flowering.

The next stage is to remove the amount of light so that the plants receive either equal or greater amount of darkness (such as in fall/autumn), and this triggers the plants to flower, which produces the bud.

In the flowering stage, the plants are even larger. Which means more trimming, and more waste.

And throughout all stages of the cannabis plant’s life cycle, the grower is battling pests and disease, which can cause plants to die. Which means more waste.

In every growth cycle, the grower will lose plants. The grower never harvests 100% of the plants he or she started with. There is always attrition. Too much water, not enough water, too much nutrients or nutrient deficiencies, mildew or mold from too much humidity, or attack from pests and mites, the grower is at war all the time, fighting to keep plants healthy and thriving. But 100% survival never happens, and therefore wasting plants is part of the business.

So now you have a clear picture of why there is an issue of waste in the cannabis cultivation. And when there is waste, there is an issue of disposal. What do you do with the waste? Throw it in the trash? Let’s discuss how Oklahoma law has addressed this issue.

Oklahoma Law allows some waste to be disposed of by the grower, but requires other forms of waste to be disposed of by a Waste Disposal Company

The Oklahoma legislature enacted new laws in 2019 that address medical marijuana waste disposal. What they did was limit what types of waste can be disposed of by the grower and what types of waste must be disposed of by a licensed waste disposal company.

Under current Oklahoma law, a medical marijuana grower can dispose of four types of waste without hiring a third-party disposal company:

  • Root balls;
  • Stems;
  • Fan leaves; and
  • Seeds

Essentially, the grower can basically dispose of anything during the Vegetative stage of cannabis. However, what is missing from that list is flowering plants and buds.

So as the grower battles disease and pests during the flowering stage, and therefore encounters attrition due to the same, the grower will now face the issue of disposing of bud rot and sick flowering plants. These are cannabis plants that have actual buds of them, but depending on the age of the plant, the buds could be tiny little pre-flowers or they could be full blown colas.

Oklahoma law requires the grower to document the amount of the waste in pounds and then to contact a licensed disposal company to pick up the wasted material.

What are legal methods of disposing of medical marijuana waste in Oklahoma?

So as long as the grower is disposing only of stems, roots, seeds, and fan leaves, the grower can destroy these by-products in-house without having to hire an independent disposal contractor.

Under the current law, the grower can use the following methods for disposal:

  • Open Burning
  • Incineration
  • Burying
  • Mulching
  • Composting
  • Any other method approved by the Department of Environmental Quality

However, the grower must abide by local laws. So if the grow facility is within city limits, it is very likely there is a local ordinance that prohibits open burning of trash. But rural growers may not have those same limitations.

If the grower chooses the method of “mulching” the waste, the grower may then remit that waste to a normal dump site or trash disposal.

Oklahoma Cannabis Growers must document their waste disposal in writing and maintain records.

Oklahoma law requires that growers document the amount of waste in writing. That means that your grow facility should keep a written log. Here are the steps your grow facility should take.

Before disposing of the waste (i.e. before you burn it, mulch it, etc.), the grow technician should first weigh the waste and document the weight in pounds.

  • On the written log, first record the date.
  • Then, write down the weight, in pounds, rounding to the third decimal.
  • Next, write down the method of disposal (did you incinerate it, mulch it, bury it, etc).
  • Last, the grow technician should sign off on it. This way, the grow facility has a log as to which employee handled the waste that day.

The reason for the last point is because of a section in the law that states: “Such documentation shall contain a witness affidavit and signature attesting to the lawful disposal of the medical marijuana waste under penalty of perjury.” Title 63, Section 429, Okla. Statutes.

The grow facility should maintain these logs for a period of five years.

Is the Oklahoma Medical Marijuana Waste Management Act good policy?

All law first begins with policy; that is, the reason for the law. Laws are meant to solve problems. First, identify the problem. Then come up with a solution. The question of whether a law is good policy deals with whether the rule actually addresses the underlying problem.

In the case of medical marijuana disposal, the position of the Oklahoma Bureau of Narcotics is that such waste could hit the streets and further contribute to the black market.

However, consider what exactly would have to happen. Scouts for the Black Market would simulate a homeless person and go dumpster diving for composted and mulched bud rot. That’s right. The material being wasted is bud rot and plant material infected with other disease, such as powdery mildew and spider mites. And while those products could still be smoked and consumed, they could not be after utilization of one of the prescribed legal methods (composting, mulching, incineration, etc).

Therefore, it is the position of this law firm that the Oklahoma Waste management Act is not good policy, because it requires a grower to resort to additional expense in hiring an outside company to dispose of certain by products that could easily and safely be disposed of in-house.

Nevertheless, the law is the law, and if you intend to last in this business, you will need to comply with rule and document your compliance.

Regulators have made a lot of changes to Oklahoma cannabis laws in recent months that affect businesses, patients, caregivers, and physicians. Some of the changes went into effect in August 2019 and others went live a month later in September under a set of temporary, emergency rules. Additional changes will be implemented through November with permanent rules expected to be released in 2020.

As you can imagine, things have gotten confusing with what seems like a constant state of change being the norm in Oklahoma lately. To make sense of everything that is happening, Leafy Green Agency has broken down the key changes for medical cannabis businesses, patients, caregivers, and physicians in a simple way that we hope makes the new rules easier for you to understand.

Changes for Cannabis Businesses in Oklahoma

The new cannabis laws in Oklahoma have a significant effect on businesses and business licenses. New transporter licenses have been added, application processing timelines have changed, and more.

Let’s take a closer look.

License Application Approvals

Regulators now have 90 days to approve business license applications, which is a significant increase from the 14 days previously required.

New Transporter License and Individual Transporter Agent Card

Previously, growers, processors, and dispensaries were issued a transporter license with their business licenses. This will still be the case but a new transporter license has been added for businesses that only want to transport cannabis.

In order to transport medical marijuana, both a business transporter license and an individual transporter agent card are required. The individual transporter agent card allows the employee, agent, or owner who applies for and is awarded the card to transport medical cannabis on behalf of a licensed transporter business.

License Residency Requirements

Under the new Oklahoma rules, proof of residency for the last two years prior to the date of a license application or renewal is now required. Alternately, five continuous years of residency during the last 25 years before the license application or renewal is submitted satisfies the residency requirement.

Furthermore, businesses must be able to prove that at least 75% of the owners are Oklahoma residents based on the above proof of residency rules.

Certificate of Compliance

All business license applicants are now required to provide a certificate of compliance from the local government where they’ll operate. This document must certify that the business is compliant with all zoning, municipal ordinances, safety, fire, electrical, plumbing, waste, construction, and building specification codes and laws.

Business Location

The new Oklahoma rules add preschools to the types of schools that cannabis dispensaries must not operate within 1,000 feet. Homeschool locations, daycare centers, and childcare facilities still aren’t included under the regulation’s definition of the term school.

Seed-to-Sale Tracking System

Oklahoma medical marijuana businesses are now required to use an inventory tracking system to track the entire lifecycle of medical marijuana. The state does not require that businesses use a specific seed-to-sale tracking system, but the system they choose to use must integrate with the seed-to-sale tracking system established by the Oklahoma Medical Marijuana Authority (OMMA). The state system is expected to be selected in 2020.

Lab Testing

A new testing laboratory license has been created which is expected to be available in 2020. The new laws require that growers and processors use a licensed testing laboratory to test cannabis harvests and product batches prior to sale, transfer, or processing.

Also, a licensed lab owner may not have a beneficial ownership interest (direct or indirect) in a licensed dispensary, grower, or processor.

Packaging and Labeling

Packaging must be child-resistant and include a universal symbol for THC, the THC content, and a statement that the product has been tested for contaminants. In addition, labels and packages cannot include cartoon characters or make claims of health or physical benefits.


Licensed growers are now allowed to sell seeds, flowers, and clones to other licensed growers, and licensed dispensaries can now sell to other licensed dispensaries.


The OMMA’s inspection authority increased under the new rules, which say that with prior notice, the OMMA can inspect all licensed businesses two times per year or anytime necessary based on violations.


A new license category will be available in Oklahoma on November 1, 2019 for waste facilities.

Changes for Cannabis Patients, Caregivers and Physicians in Oklahoma

While the number of changes to Oklahoma’s cannabis laws are fewer for patients, caregivers, and physicians, they’re no less significant than the state’s changes to laws for businesses.

Patients in Oklahoma may now get medical marijuana recommendations from podiatrists who are licensed by and in good standing with the Board of Podiatric Medical Examiners. In addition, 100% disabled veterans can pay a reduced medical marijuana card application fee of $20 rather than the full $100 fee.

Oklahoma regulators have also added reciprocity rules with the introduction of short-term licenses for patients. These temporary licenses are valid for 60 days for out-of-state visitors who submit a 60-Day Physician Recommendation Form that is approved by OMMA.

For both patients and caregivers, OMMA had 14 calendar days to review and respond to patient and caregiver card applications submitted prior to May 7, 2019, but that time frame has changed to 14 business days.

What’s Next for Oklahoma?

Change is common in the cannabis industry and laws are updated and revised frequently. Medical marijuana sales in Oklahoma are expected to reach $140-180 million in 2019, which is just the first full year of the program’s operation.

With more growth expected in 2020 and beyond, it’s safe to assume the state’s regulators will make more rule changes as the industry evolves.
