At VIST Labs, innovative cryogenic pasteurization technology addresses one of the industry’s most pressing issues: microbial contamination. With more than 100 patents and three decades of experience in food, pharmaceutical, and cannabis packaging, Jim Sanfilippo is revolutionizing cannabis safety.

 

In a market valued at $35 billion, Sanfilippo’s breakthroughs are essential for cannabis brands aiming to uphold product quality while managing intricate regulatory hurdles.

 

From Nuts to Frozen Nuggs: A Journey of Packaging Innovation

 

Jim Sanfilippo’s expertise in packaging didn’t begin with cannabis. His roots trace back to his family’s food business, where his innovations revolutionized how perishable goods were preserved. Sanfilippo’s pioneering work in oxygen-free packaging started with something as simple as nuts. Recognizing that oxygen was a key factor in the degradation of food, he developed advanced packaging methods that extended shelf life and maintained product freshness. These early breakthroughs in food safety laid the foundation for future innovations in both the food and pharmaceutical sectors.

 

Sanfilippo’s packaging methods were created to preserve the integrity of delicate goods by removing oxygen from the surrounding air and preventing contamination and spoiling. This strategy proved to be so effective that it attracted the interest of significant figures in the packaging sector. After selling two of his company’s divisions to packaging behemoth Sonoco in 2017, Sanfilippo made the decision to concentrate his skills on a brand-new, quickly expanding market: cannabis.

 

“Cannabis is a $35 billion industry in the U.S., but it faces significant challenges with microbial contamination,” Sanfilippo says. Sanfilippo recognized an opportunity to apply similar concepts to cannabis, keeping the plant’s potency, flavor, and safety while solving the industry’s essential issue of contamination. His packaging solutions have previously prolonged the shelf life of other goods. His transition from food to cannabis was more than simply a financial decision; it was a logical step for a seasoned entrepreneur trying to address complicated issues in a field ripe for disruption.

Today, Sanfilippo’s innovations in cannabis packaging mirror the same meticulous approach he took in his family’s food business, ensuring that every product remains as potent and pure as the day it was harvested.

 

Cryogenic Pasteurization: The Cannabis Industry’s Hidden Solution

 

VIST Labs’ invention centers on cryogenic pasteurization, a procedure that sterilizes cannabis while retaining its natural components using medical-grade cryogenic vapor. “Cannabis is often contaminated with yeast, mold, and harmful pathogens like Aspergillus,” adds Jim Sanfilippo.

 

He explains that traditional sterilizing procedures, like as gamma radiation or ozone, might harm cannabinoids and terpenes, resulting in lower-quality goods.

 

How it works…

 

VIST’s method lowers oxygen levels to prevent oxidation and stop microbial growth without compromising product integrity. The process starts by loading 4-5 pounds of cannabis into a product cassette, which is then placed inside the pasteurization machine, a refrigerator-sized unit.

 

The VIST chamber is then activated, using cryogenic vapor formed by vaporizing liquid nitrogen at -320°F and combining it with a medical-grade atmosphere.

 

In just 90 to 150 seconds, the chamber fills with vapor, reducing oxygen levels to as low as 95%, effectively eliminating harmful microbes like Aspergillus, E. coli, and Salmonella.

 

Once sterilized, the product is rapidly cooled with liquid nitrogen, preventing oxidation. Finally, a HEPA filtration system purifies the air, removing any residual contaminants and ensuring the cannabis is packaged in aseptic, low-oxygen conditions for maximum purity and stability.

 

A Modular Solution for the Cannabis Industry

 

VIST Labs’ cryogenic pasteurization machines are built with modularity in mind, providing flexibility for both mid-sized cultivators and large-scale operations. “We can operate in cassette mode at 25 pounds per hour, or scale up to our high-output setup, handling up to 40 pounds per hour,” said Jim Sanfilippo in an interview.

 

But VIST Labs’ system is more than just a sterilization machine—it’s a comprehensive packaging solution. After sterilization, the cannabis is transferred into a bulk device that packs it into bags of various sizes, ranging from one to ten pounds, or into smaller pouches for quantities like an eighth-ounce. “Our system includes a cooler, pouch bagger, and other components that work together to maintain a near-zero oxygen environment,” Sanfilippo explained.

 

This scalability makes VIST’s technology suitable for a wide range of cannabis businesses, whether they’re aiming to meet strict medical market standards or preserve medical-grade crops for export.

 

The aseptic packaging system adheres to European Pharmacopoeia standards, ensuring compliance in both domestic and international markets.

 

VIST’s forward-thinking technology also prepares cannabis companies for potential federal legalization. As federal oversight looms, Sanfilippo emphasizes that more stringent regulations, particularly around truth-in-labeling, will make compliance technologies like theirs vital for long-term success.

 

“With our system, we offer protection for the crop year and complete microbial control for up to a year,” said Sanfilippo, noting that VIST expects to package nearly 150 million pounds of outdoor-grown cannabis in 2023 alone.

 

Beyond decontamination, VIST’s system addresses a critical issue in the cannabis industry: the degradation of THC potency over time. Fluctuating oxygen levels in packaging often result in mislabeled products, leading to recalls and regulatory consequences.

 

“Within 45 to 50 days, THC levels can degrade by 10% or more, making label claims inaccurate,” said Sanfilippo. VIST’s modified atmosphere packaging (MAP) ensures product stability for up to a year, helping brands stay compliant and maintain product safety.

 

Bottom Line

 

VIST Labs, led by packaging innovator Jim Sanfilippo, is transforming cannabis safety and preservation with its cryogenic pasteurization technology. By freezing cannabis at -320°F, this groundbreaking process effectively eliminates microbial contamination without compromising the plant’s integrity. Offering scalable, modular solutions for cultivators of all sizes, VIST Labs ensures compliance with stringent industry standards, both in the U.S. and internationally. As the cannabis market expands and federal regulations tighten, VIST’s forward-thinking technology positions brands for long-term success by maintaining product quality, extending shelf life, and safeguarding potency—crucial elements in a $35 billion industry.

Scientists Now Think That One Compound in the Cannabis Plant Can Replace All Opiates

replace opiates with cannabis

Which Cannabis Compound Do Scientists Think Can Replace Opiates?

…And Why This Is Important

Opiates are a type of pharmaceutical drug that’s been made from the opium poppy plant. While it’s somewhat a ‘natural’ substance that’s been extracted from the fibers and sap of the opium poppy plant, these are extremely dangerous sedatives that act on the central nervous system. However, there are completely synthetic opioids as well, which are manufactured entirely in laboratories.

Famous examples of well-known and widely-used opiates today include heroin, codeine, and morphine. They all work similarly, binding to the brain’s opioid receptors and users feel a drastic reduction in pain. It also causes users to feel euphoric, drowsy, or sleepy. Common side effects include constipation and nausea.

Because opiates are powerful for dulling one’s pain perceptions, they have become commonly prescribed by doctors and hospitals for pain relief. That said, opiates have become one of the world’s most addictive, dangerous, and fatal drugs – and you can get prescribed it right by your very own physician. Repeated use of opiates can easily lead to dependence and addiction, and eventually consuming high doses can drastically slow down breathing, and cause brain damage, or even death.

Since doctors still keep prescribing opioids, this has resulted in the deadly Opioid Epidemic, which has killed thousands of people. It’s a worrisome public health crisis, most especially because of fentanyl, an illegally manufactured opioid which is said to be 50 times more potent than heroin.

Could The Answer To The Opioid Epidemic Lie In Cannabis…Terpenes?

The past few years have shown that cannabis legalization is critical for surviving the opioid epidemic, and reducing overall opioid consumption.

The results of a recent research paper, which builds on past studies conducted by Dr. John Streicher, who is a member of the Comprehensive Center for Pain and Addiction, reveals fascinating findings. According to Streicher, cannabis terpenes were found to provide relief in inflammation models as well as on neuropathic pain caused by chemotherapy.

For the study, Streicher and his research team analyzed 4 kinds of terpenes that are found in mid to high levels in Cannabis sativa plants: linalool, geraniol, beta-caryophyllene, and alpha-humulene. They discovered that each terpene produced significant pain relief among mice subjects with fibromyalgia and post-operative pain, and among the terpenes, geraniol was found to be the most powerful.

“Our research is showing that terpenes are not a good option for reducing acute pain resulting from an injury, such as stubbing your toe or touching a hot stove; however, we are seeing significant reductions in pain when terpenes are used for chronic or pathological pain,” he said. “This study was the first to investigate the impact of terpenes in preclinical models of fibromyalgia and post-operative pain and expand the scope of potential pain-relieving treatments using terpenes,” Streicher said.

Cannabis terpenes are the compounds responsible for the aromatic profile of each strain; they are located in the plant trichomes. Not only do they contribute to each strain’s unique flavor and odor, but they also have valuable therapeutic and medicinal benefits. There are around 150 kinds of terpenes known today, though in the entire plant world, there are known to be some 20,000 terpenes.

Understanding the therapeutic benefits of terpenes is incredibly valuable also because they don’t contain THC (tetrahydrocannabinol), the compound in marijuana that gets you high.

“With fibromyalgia, there isn’t much of an understanding of what the pain state is, and there are not a lot of great options for treating it,” explains Streicher. “Our findings show that terpenes may be a viable treatment option for fibromyalgia pain, which could potentially have a large impact and make a difference for an under-treated population.”

Other Studies

This is not the first time that cannabis terpenes have been found to demonstrate excellent pain-relieving properties. It must be noted that just like what Streicher says, terpenes seem to do better with chronic pain management, instead of acute pain management.

Another study from 2024, which was published in The Journal of the Association for the Study of Pain, was conducted by researchers at the University of Arizona and the National Institutes of Health. The investigators analyzed the analgesic properties of different terpenes including geraniol, humulene, linalool, pinene, and caryophyllene among mice subjects with chemotherapy-induced peripheral neuropathy.

According to the researchers, all the terpenes delivered analgesic effects that were equivalent to around 10 mg/kg of morphine. It was also interesting to note that administering both morphine and terpenes together at low doses resulted in ‘enhanced’ pain-killing effects.

“Together these studies identify cannabis terpenes as potential therapeutics for chronic neuropathic pain,” said the investigators.

There have also been other studies that have found that combining cannabis with opioids can indeed provide long-lasting pain relief. It comes with the added benefit of reducing opioid doses needed for effective pain control. This phenomenon is called opioid-sparing. These types of protocols can be beneficial for patients who suffer from severe, chronic pain caused by cancer, arthritis, joint problems, fibromyalgia, diabetes, post-surgical pain, migraines, nerve damage, and so much more.

Conclusion

Learning more about the pain-killing properties of terpenes is extremely valuable for the medical community, patients, and even society as a whole. We can all do with less opioid addictions because it has torn families apart, and caused the deaths of thousands of people.

Terpenes, or cannabis in general, offer a natural and safe alternative that can be complementary to other pharmaceutical treatments designed to reduce pain.

Cannabis and the Authoritarian State

Cannabis and the Authoritarian State

Cannabis has been legal for longer than it has been illegal. Let that sink in for a minute. For thousands of years, humans cultivated and consumed cannabis freely across civilizations and continents. It wasn’t until the early 1900s that we witnessed a massive push to drive hemp and cannabis into the black market, primarily due to industrial competition from petrochemicals, pharmaceuticals, and other industrial applications.

What makes cannabis so threatening to powerful interests? For starters, hemp and cannabis are highly versatile crops with over 50,000 different uses, from medicine to textiles to fuel. Even more remarkable is how this plant is hardwired to work with the human body through our endocannabinoid system—a biological network we didn’t even discover until the 1990s.

Perhaps most threatening of all is that cannabis is insanely easy to grow. This means that if the plant helps you with a particular physical ailment, you have the ability to grow your own medicine indefinitely. No insurance premiums, no wait lists, no pharmaceutical middlemen—just you cultivating your own healing directly from the earth.

Authoritarians do not like this, not one bit. When people can meet their own needs independently, power structures lose their grip. When citizens can think differently without permission, control systems begin to fail. So today, we’re going to look at the interesting relationship between authoritarianism and cannabis, and how this humble plant plays a key role in keeping you free.

We’ve already established the versatility of cannabis, but there’s another element that those old D.A.R.E. PSAs inadvertently reveal about what authoritarians think about cannabis. I’m talking, of course, about “behavior.” You see, in an authoritarian system, you and I are but cogs in the machine. We’re the expendables who should be proud to work ourselves to death for our “fearless leaders.”

This is precisely why certain ideas, philosophies, religions, movements, books, and substances are typically banned in authoritarian regimes. Take North Korea as an example: everything from the type of television citizens watch to the music they hear is a tightly spun spell designed to keep the populace in check. While they don’t have explicit laws against hemp (they actually grow it industrially), smoking psychoactive cannabis is strictly forbidden.

Contrast this with places like Malaysia, where you can get up to 5 years for possessing just 20 grams of cannabis, and even face the death penalty depending on the situation. These authoritarians don’t play around when it comes to cannabis because they know it affects the behavior of their populace in ways they can’t control.

The question becomes: what behavior do they fear so much that cannabis produces within the individual?

The answer is a critical mind. People who consume cannabis often begin to question their own belief systems. Most regular users undergo some transformation in their values and perspectives. Cannabis has a unique way of helping people see beyond cultural programming and think outside established paradigms. It can make the familiar strange and the strange familiar—a psychological state that’s antithetical to authoritarian control.

This independent thinking runs counter to the narrative of authoritarians who wish to maintain a tight grip on social consciousness. If even 10% of a population begins to pivot in their behavior within a regime, it can have massive ripple effects. Just look at cannabis in the US—it went from being demonized to being embraced by the majority in less than 80 years, despite massive propaganda efforts.

For authoritarians, psychoactive cannabis isn’t primarily a threat to public health and wellbeing—it’s a threat to the health and wellbeing of authoritarianism itself. When people start thinking differently, they start living differently. When they start living differently, they start demanding different. And that’s the beginning of the end for any system built on unquestioning obedience.

Beyond the threat to thought control, there’s another reason why drugs in general remain illegal: the state can use prohibition as a weapon against the populace. This isn’t conspiracy theory—it’s documented history.

Take Nixon’s war on drugs. His domestic policy chief, John Ehrlichman, later admitted: “We knew we couldn’t make it illegal to be either against the war or black, but by getting the public to associate the hippies with marijuana and blacks with heroin, and then criminalizing both heavily, we could disrupt those communities.” Nixon essentially placed cannabis on the Controlled Substances Act because he needed an excuse to shut down anti-war protests and target Black communities.

Since hippies and anti-war protesters were smoking “freedom grass,” making it illegal would circumvent their freedom of speech and freedom of assembly, and more importantly—turn free citizens into state property. It’s a win-win if you’re an authoritarian looking to silence dissent.

Then there’s the whole “boogeyman” complex that prohibition creates. We’re told “drug dealers” are roaming the streets preying on innocents, giving them “marihuanas” so they can do vile things. What the government conveniently leaves out is how the banks these “dealers” use to launder their money remain untouched. They don’t mention the shadier dealings of law enforcement either—like running guns into Mexico (eventually leading to the death of one of their own), or spraying poison on crops, killing and hospitalizing people because, you know…”Drugs are bad!”

Authoritarians cannot let go of the value that keeping the most widely used illicit substance in the world illegal provides them. This explains why the US hasn’t federally legalized cannabis despite nearly 80% of Americans supporting some form of legalization. It’s not because they don’t have enough research or that they’re genuinely concerned about public health—it’s because prohibition gives them all the privileges of violating constitutional rights while siphoning money into their coffers.

Drug prohibition creates a perpetual enemy that can never be defeated, allowing endless justification for surveillance, militarized police, asset forfeiture, and expansion of state power. What authoritarian could resist such a convenient tool?

Cannabis is a plant. You can’t make nature illegal—it’s counter to the human experience. When governments attempt to criminalize a naturally occurring organism that humans have cultivated and used for thousands of years, they reveal the absurdity of their position and the limits of their authority.

While the United States isn’t a full-on authoritarian state (yet), the truth is that many authoritarian elements have played out over the years. You only need to look as far as the war on drugs to see how the state utilizes prohibition as a weapon to their advantage. From no-knock raids to civil asset forfeiture to mass incarceration, drug laws have erected a parallel legal system where constitutional protections often don’t apply.

The fundamental truth is that cannabis is not only versatile and medicinal, it gives you back your autonomy in multiple ways. It helps you think for yourself. It allows you to grow your own medicine. It connects you with a plant that humans have used ceremonially, medicinally, and industrially throughout our history. And this autonomy is something authoritarians cannot stand—free individuals who know how to think beyond the narratives they’re fed.

Cannabis doesn’t just get you high—it offers a perspective from which the absurdities of prohibition become glaringly obvious. Perhaps this is why, as state after state legalizes, we’re witnessing the slow but steady unraveling of one of the most enduring authoritarian policies in American history.

So if you count yourself among those who value freedom of thought and bodily autonomy, who believe that nature doesn’t require government permission, and who understand that true liberty includes the right to explore your own consciousness—well, maybe it’s time to toke one up for freedom!

Don’t Fertilize Your Weed with Bat Poop

 

Fertilization is a critical step for growing healthy marijuana plants.

They help provide essential nutrients for marijuana in various stages of growth, while promoting plant growth. There are dozens of different fertilizers to choose from in the market; growers can choose based on budget, nutrients needed, location, season, and much more. But not all fertilizers are made equally – of course, some are of better quality than others.

That said, there are some rather unusual fertilizers that can be used on plants. These may include, but are not limited to: coffee, milk, grass clippings, banana peels, fish tank water, potato water, and even urine! Yes, it does sound strange, but to gardening enthusiasts, there is nutritional value to be found in each of these things, which can make them suitable fertilizers depending on the circumstances.

For example, grass clippings make excellent mulch and can provide potassium, nitrogen, and phosphorus. Urine is a potent source of nitrogen as well as phosphorus. Banana peels are rich in calcium, which is excellent for promoting root growth while helping supply oxygen to the soil.

But what about bat poop? Also known as guano, bat poop has been said to work as a plant fertilizer because it’s rich in nitrogen, potassium, phosphorus, and other nutrients. Unfortunately, using bat poop as a plant fertilizer can also be dangerous. So if you don’t really know what you are doing, bat poop as a fertilizer can be extremely risky.

Bat Poop Fertilizer Kills 2 NY Men

On December 2024, news of two men hailing from Rochester, New York, dying went viral.

The cause of death was dangerous fungus, in the bat poop that they were using to fertilize their marijuana plants. Both men grew their own marijuana plants for medical consumption, but unfortunately developed histoplasmosis after breathing toxic fungal spores from the guano.

One of the men was aged 59 years old; he bought bat poop online to use as fertilizer for his plants. Meanwhile, the other was a 64-year-old male who found guano in his attic, then decided to use it to fertilize his cannabis plants. They both developed similar symptoms, including chronic coughs, fever, severe weight loss, and respiratory failure. The case was also discussed in the Open Forum Infectious Diseases medical journal.

Is there a safe way to use bat poop as fertilizer? If you ask me, I truly can’t understand why one would use guano as fertilizer when there are so many other proven safe alternatives out there that are simply not as risky. According to the University of Washington, one must always wear a dust mask each time you open a bag containing soil amendments. That’s because a mask will greatly decrease the chances of breathing in fungal spores, which could be potentially dangerous. They also go on to explain that yes, guano is indeed used as fertilizer for its valuable nitrogen content but it still isn’t without its own risks, particularly of developing Histoplasma – the same condition that killed the two men.

Make Your Own Safe Fertilizers At Home

There are many other safe, affordable – and even free – fertilizers you can feed your marijuana plants with. It doesn’t have to cost a fortune nor does it have to be risky to your health.

Check out these easy, low-cost, DIY fertilizers for weed:

 

  • Coffee grounds are abundant in nitrogen, which makes it perfect for the vegetative stage of marijuana plants. They are also a fantastic source of organic materials and green waste, which contain other vital nutrients. When the coffee grounds decompose, they create soil aggregates that improve soil aeration and its water retention capabilities.

 

Mix around 2 grams of coffee ground for every liter of soil. Measuring its pH levels is also helpful, since you want it to be between 6 to 6.5

 

  • Crushed eggshells are a great way to ensure no eggshells go to waste. It’s rich in calcium plus other minerals that are effective in improving overall plant structure, health, and growth. In fact, so many gardeners and farmers commonly use crushed eggshells to help boost plant growth – and it will work just as well for marijuana plants.

 

They’re really easy to use, too! Just mix eggshells into the soil, or steep them into water then pour into the soil for a calcium-packed feed.

 

  • Banana tea or water is rich in potassium and magnesium, making it perfect as a feed during the marijuana plant’s flowering stage. You can use banana peels differently: with 3 to 5 banana peels, soak it in water for 2 days. Then you can use the water on your plants, and even leave the banana peels as compost for your garden.

 

  • Wood ash from your fireplace or other sources is a great source of phosphorus and potassium. Simply sprinkle some wood ash over marijuana during the final flower phase. Just use 1 or 2 grams of ash for every liter of substrate. Be careful not to use too much wood ash, or it can make the soil too alkaline.

 

  • Animal manure, such as those from cows, rabbits, or horses, make excellent organic fertilizers. Just be sure that they’re composed properly so that you avoid introducing weed seeds, or pathogens.

 

These low-cost fertilizers are also natural and effective. There’s no reason for you to turn to bat poop as fertilizer, even if you’re in a bind.


Conclusion

Guano or bat poop is a poor choice of fertilizer if you don’t know what you are doing. It’s risky and potentially dangerous – just not worth it. Instead, fertilize your marijuana plants with these options mentioned.
