1. Why Total Yeast & Mold Testing Matters
Total Yeast and Mold (TYM) testing is a regulatory requirement in Oklahoma for dried cannabis flower and certain cannabis products. These tests measure colony-forming units (CFUs) to ensure microbial levels are within safe limits for consumers.

• False Pass: A contaminated product reaches consumers, risking public health and triggering a recall.
• False Fail: A perfectly safe product is destroyed or remediated unnecessarily, costing your business time and money.

Accurate results matter—not just for compliance, but for your reputation.

2. Staying Current with Vendor SOPs
Methods evolve as new data emerges. For example, the 3M™ Rapid Yeast and Mold Plates method was originally validated to be read at 48 hours for dried cannabis flower. Updated validation now requires plates to be read at 60–72 hours to ensure accuracy (source).
At OKCTL, we immediately implement vendor SOP changes to keep your testing in full compliance. Unfortunately, some labs still read plates at 48 hours—potentially reporting inaccurate results that could lead to compliance issues down the road.

3. The Dilution Factor: Getting the Math Right
Every TYM test starts with a homogenized sample and serial dilutions to achieve a countable plate.

• Even a small math error in dilution calculations can drastically alter results.
• Our analysts follow documented calculation procedures in strict accordance with the method to eliminate guesswork.
• All calculations are recorded and reviewed during our quality review process before results are released, ensuring accuracy and defensibility if audited.

4. Beyond the Plate: Environmental Controls
Yeast and mold can come from many sources—including the lab itself. We conduct regular environmental monitoring, use positive and negative controls in testing, and maintain strict contamination control procedures. If your lab isn’t monitoring its own workspace, it’s increasing your risk.

5. Quality Review Before Every Release
Before any Certificate of Analysis (COA) leaves our lab, it goes through our Quality Department for a full compliance and accuracy review. This ensures:

• Method adherence
• Correct calculations
• Proper documentation for regulatory audits

6. Your Partner in Compliance
We believe in transparent communication. If there’s a regulatory or method change that affects you, you’ll hear it from us first. Our goal is to be more than a lab—we’re your compliance partner.

The psychoactive properties of cannabis, such as the “high,” are caused by the cannabinoid THC. To exert its actions, it binds to receptors in the brain and central nervous system. THC is a strong analgesic that has been demonstrated to be beneficial in the treatment of multiple sclerosis, glaucoma, and chronic pain.

 Conversely, CBD doesn’t have the same intoxicating effects as THC. Numerous therapeutic advantages have been demonstrated for it, including lowering anxiety and depression, reducing pain and inflammation, and even treating some forms of epilepsy. When compared to THC, CBD binds to distinct receptors in the body, such as those implicated in anxiety, pain, and inflammation.

Cannabis contains additional cannabinoids, such as cannabigerol (CBG) and cannabinol (CBN), as well as terpenes, which are fragrant molecules that give the plant its characteristic smell. The “entourage effect” describes how these substances interact to produce cannabis’s diverse medicinal effects. It is necessary to understand the chemical makeup of cannabis in order to use it safely and efficiently for medical purposes.

The endocannabinoid system is a sophisticated cell-signaling pathway that is essential for controlling a wide range of physiological activities, including as appetite, mood, pain, and inflammation. It is made up of endocannabinoids, receptors, and enzymes that cooperate to keep the body’s homeostasis. The endocannabinoid system’s two main receptors are CB1 and CB2, and they can be found in the brain, immune system, gastrointestinal tract, and other areas of the body.

Medical marijuana, commonly referred to as medical cannabis, includes substances known as cannabinoids that interact with the endocannabinoid system to create a range of therapeutic effects. Tetrahydrocannabinol (THC) and cannabidiol are the two principal cannabinoids present in marijuana (CBD). While CBD is non-psychoactive and has anti-inflammatory, anti-anxiety, and analgesic characteristics, THC is what gives marijuana its psychoactive effects.

 Consuming THC causes the brain’s CB1 receptors to bind, resulting in a high or altered state of awareness. Patients who suffer from diseases including chronic pain, motion sickness, or appetite loss may find this impact to be helpful. On the other hand, CBD interacts with various receptors and enzymes in the endocannabinoid system rather than directly binding to CB1 or CB2 receptors. In addition to reducing inflammation, anxiety, and sadness, it can also lessen epileptic patients’ seizure activity.

The use of medicinal marijuana is still a source of contention among medical professionals and legislators, as its efficacy and safety have yet to be thoroughly investigated. Recent studies have nonetheless demonstrated that medical cannabis can be a useful tool for controlling the symptoms of several medical diseases. For instance, it has been discovered that medical marijuana helps people with cancer, neuropathic pain, and multiple sclerosis manage their chronic pain. In chemotherapy patients, it can help increase appetite and lessen nausea. In conclusion, the endocannabinoid system is essential for controlling a variety of bodily physiological activities. By interacting with this system, the cannabinoids in medical marijuana can have therapeutic effects such lowering pain, inflammation, anxiety, and nausea. The processes underlying the interactions between the endocannabinoid system and medicinal cannabis require more study, but current data suggests that it can be a useful tool for treating the symptoms of some medical diseases.

Cannabis, also called marijuana, has a complicated history of production and use. For thousands of years, different cultures have found a variety of unique uses for this plant. The Greeks and Romans, for example, famously used cannabis for recreation and religion. However, cannabis is thought to have originated in Central Asia, now modern-day Mongolia and southern Siberia, where the ancient Chinese utilized it for medical purposes. 

In medieval Europe and the Middle East, the plant’s fibers were used to manufacture textiles, paper, and rope. Cannabis was widely utilized in Western medicine by the late 1800s to treat a wide range of illnesses, including pain alleviation, hunger stimulation, and disorders including epilepsy and migraines. However, as its usage as a recreational drug grew in popularity throughout the 20th century, concerns about its abuse potential and the risks of its use grew. 

After the Marihuana Tax Act was passed in 1937, cannabis became illegal in the United States at the beginning of the 20th century. Despite this, its usage rose, particularly among young people, giving rise to the “War on Drugs” and further initiatives to stifle its use and distribution. Despite these initiatives, cannabis use increased, prompting an upsurge in calls for its legalization. 

In recent years, attitudes towards cannabis have undergone a significant shift, with a growing number of countries legalizing its use for medicinal or recreational purposes. In the United States, several states have legalized cannabis for recreational use, while many others have legalized it for medicinal purposes. The legalization of cannabis has sparked a growing industry, with businesses developing a wide range of products, including edibles, tinctures, and other forms of the drug. The future of cannabis and its use remains uncertain, but its history and impact on society will continue to evolve. 

The history and evolution of cannabis regulation 

Cannabis, popularly known as marijuana, has been regulated for a very long time. Cannabis has been used for both therapeutic and recreational purposes for thousands of years. However, several nations, including the United States, started to enact legislation criminalizing its use, sale, and possession around the beginning of the 20th century. Although the motivations behind this change in policy varied, they frequently reflected moral and racial prejudices towards the drug-using groups as well as worries about its consequences on public health and safety. 

A growing push to legalize marijuana gained traction in the second half of the 20th century, in part due to the expanding understanding of its therapeutic advantages. Numerous states in the United States have decriminalized the drug and made it legal for medical use in others. The first states to legalize cannabis for recreational use were Colorado and Washington in 2012, which sparked a global legalization movement. 

Cannabis legalization has gained popularity in recent years as more and more nations choose to regulate and tax the drug rather than prohibit it. A vibrant legal cannabis economy has resulted from this, with businesses making and offering a variety of goods derived from cannabis, including oils, edibles, and concentrates. However, many nations continue to impose harsh regulations against marijuana usage, and several nations, including the United States, still forbid its use on a federal level. 

Cannabis regulation is still a contentious, polarizing issue with strong arguments on both sides.  Supporters of legalization contend that it can increase tax revenue, lower crime, and give individuals who require the drug for medical purposes access to a safe and controlled source of it. Critics, on the other hand, are concerned about the drug’s negative health consequences as well as the potential repercussions of legalization on communities and young people. Despite these ongoing arguments, the trend toward legalizing and regulating cannabis shows no indications of slowing down. The direction of cannabis regulation will likely be determined by how much we continue to learn about the drug and its effects. 

The history of medicinal marijuana: Explore the historical use of marijuana for medical purposes, from ancient civilizations to modern times. 

The ancient civilizations in what is now China and India, were among the first to employ marijuana as medicine to treat a variety of illnesses and to ease pain. Cannabis was first brought to Western medicine in the late 1800s and was quickly adopted for a variety of therapeutic uses, including hunger stimulation, pain relief, nausea relief, and control of muscular spasms. However, the early 20th century saw a drop in marijuana’s use for medical purposes due to the development of stronger medications and shifting social perceptions of marijuana. 

The medicinal usage of marijuana experienced a renaissance in the 1960s and 1970s, and numerous studies were carried out to investigate its therapeutic potential. The discovery of the endocannabinoid system, a group of receptors in the body that react to the active components in marijuana, sparked a resurgence in interest in the drug’s potential medical applications. During this time period, states such as California were among the first to legalize marijuana for medical purposes, and several other states have since followed suit. 

The usage of medical marijuana is a contentious and universally recognized topic nowadays. Many states have approved the use of marijuana for a number of medical illnesses, including chronic pain, anxiety, and epilepsy, despite the fact that federal law still classifies it as a Schedule I narcotic with no medicinal benefit. Its usage as medicine has also been made more acceptable by the FDA’s approval of marijuana-based medications like Epidiolex. To fully understand the medicinal potential and safety of marijuana as well as to identify its place in contemporary medicine, more research is still required.
