Study Raises Concerns Over Heavy Metals In Cannabis



A recent study raised concerns about the heavy metal content in cannabis plants.

In a recent report, Penn State researchers raised concerns about heavy metal contamination in cannabis, which can cause health problems such as cancer and neurological problems in users.

The report examines cannabis’ ability to absorb heavy metals, describes the health effects it has on consumers, and suggests how growers can address the problem.

Since cannabis is a phytoremediator, i.e. it extracts environmental pollutants from the soil, the toxins absorbed by the plant remain in it and in all products made from it.

Chernobyl and soil pollution

A notable example of the use of cannabis for its phytoremediation properties is the Chernobyl power plant in Pripyat, Ukraine.

On April 26, 1986, an accident occurred in reactor No. 4 of the Chernobyl power plant during a safety test on the steam turbine of a nuclear reactor.

A combination of operator negligence and critical design flaws melted the core and at least two explosions broke the reactor core and destroyed its building.

The Chernobyl disaster is considered to be one of the worst nuclear disasters in history.

Subsequent investigations of the 30 kilometer long area around the Chernobyl power plant revealed high concentrations of lead, cesium-137, strontium-90 and plutonium in the soil, in plant and animal tissues.

In 1998, hemp was grown in Chernobyl to remove pollutants from the soil and reduce toxicity.

While hemp is beneficial for removing toxins from contaminated environments, cannabis plants intended for human consumption must be clean and free of contamination.

Infinite Chemical Analysis Labs Laboratory Director Jayneil Kamdar Ph.D. says cannabis belongs to a category of plants called hyperaccumulators that can build heavy metals into the soil more quickly through their root systems.

“In fact, this hyperaccumulative ability often makes cannabis a very promising candidate for phytoremediation of heavy metals in contaminated soils,” says Kamdar. “On the other hand, additional precautions need to be taken to ensure that cannabis plants are grown in uncontaminated soil to reduce public health risks. It is imperative that all cannabis and hemp strains intended for medical or recreational use are tested in a government-certified laboratory such as InfiniteCAL before they are available on the market. “

According to InfiniteCAL, extensive test rules and regulations should be implemented to combat contamination.


According to the research team, some cannabis strains are bred to improve phytoremediation properties such as long stem length, fast growth, and high root and leaf area.

The Penn State research team learned that lead, cadmium, and chromium migrate through the stem and into the leaves and flowers, and then exit through the plant’s trichomes.

Trichomes are a major focus in the cannabis industry because the hair-like structures are where the plant stores tetrahydrocannabinol (THC) and cannabidiol (CBD) oils.

Although cannabis contaminated with heavy metals or other toxins is never safe to consume, it is of particular concern for medicinal cannabis patients.

When someone uses cannabis as medicine, it cannot contain pollutants such as heavy metals that can cause various side effects.

Health hazards from heavy metals

Louis Bengyella, Penn State Assistant Research Professor, says heavy metals like lead, cadmium, mercury, and chromium are known carcinogens.

“The heavy metal content of cannabis is not regulated; As a result, consumers could be unknowingly exposed to these toxic metals, ”says Bengyella. “This is bad news for anyone who uses cannabis, but is especially problematic for cancer patients who use medical marijuana to manage the nausea and pain associated with their treatments.”

Bengyella says smoked cannabis poses the greatest threat to human health as it can contain selenium, mercury, cadmium, lead, chromium, nickel and arsenic.

Bengyella says cannabis users, especially cancer patients, can cause unnecessary physical harm.

Arsenic can damage blood vessels and other organs and tissues in the body, and lead can affect the gastrointestinal tract and central nervous system.

Cadmium causes bone and lung damage, chromium causes cardiovascular, respiratory and other internal problems, and mercury can damage the kidneys, brain, nervous system and lungs.

In addition, heavy metals can cause other serious problems such as various types of cancer, allergies, psychosis, autism, tumors, and chromosomal aberrations.

Find a solution

Bengyella says that while the problem is at the consumer level, it needs to be addressed at the agricultural level.

Study authors say that choosing cannabis strains that were not bred for phytoremediation and using farmland free of heavy metals can reduce contamination.

The authors recommend avoiding abandoned industrial sites and performing air quality and soil pH tests before choosing a location to grow cannabis.

“A blueprint of agronomic strategies is proposed to reduce the uptake of HMs by cannabis,” the abstract of the study reads. “We show that modernizing global cannabis production requires rethinking best agronomic practices and post-harvest technologies to remove metallic contaminants.”

Cannabis Capsules Are Ultra-Efficient, But Are They Right For You?



This story originally appeared on Emjay

The future is here. Cannabis comes in an ultra-efficient smokeless pill form that you can take orally. It seems unconventional, but when you really think about it, most things come in pill form.


It’s not uncommon to see psychoactive compounds, medications, and dietary supplements in capsule or tablet form. It would be a lot weirder if you had to smoke your vitamins or your allergy medicine.

Before you run out and grab some cannabis pods, there are a few things you should know. The experience varies widely and the effects may not be for everyone.

What is a cannabis capsule?

Cannabis capsules take the extract of a cannabis plant and mix it with a type of carrier oil in pre-measured doses. The packaging will usually list how much THC and how much CBD is in each capsule. You swallow your pre-measured dose of cannabis just like you would swallow any other capsule or tablet.

Cannabis capsules are not an adjunct to smoking or vaping cannabis. You are an alternative. If you don’t like smoking or can’t smoke, cannabis capsules allow you to enjoy the high of your favorite strains without involving your lungs.

Hemp or CBD capsules are completely different

Labeling is crucial, and vague terms can sometimes be misleading. Hemp is cannabis and CBD is a cannabinoid. Hemp extract capsules, or CBD capsules, are also technically cannabis capsules. The main difference between the two is that hemp capsules will not get you high. Hemp contains less than 0.3% THC, which is insufficient to induce any noticeable psychoactive effects.

That doesn’t mean hemp extract or CBD are baseless. They’re a great way to naturally induce relaxation and create feelings of emotional well-being without altering your mind. If you want some of the benefits of weed but need to keep your mind sober, CBD capsules are great. This is a complementary way to enjoy cannabis. You can take CBD with weed without getting high.

How do cannabis capsules work?

You swallow your cannabis capsule and it reaches your stomach. Your body begins to digest and filter the cannabinoids, including the THC. They are released slowly over time, producing a high that can last up to two hours to start and up to eight hours to finally finish.

Capsules can be very polarizing. This is going to sound like an absolute nightmare to some people. If you want to be able to control your high and have a good idea of ​​when it will end, capsules are definitely not for you.

If you have a high THC tolerance and use weed for its medicinal or wellness benefits, you’ll probably love the idea of ​​a capsule. Taking one low-dose capsule twice a day will give you benefits without making you feel too high to function. It’s the perfect means to an end.

How capsules compare to other forms

Cannabis capsules work very differently than other forms of cannabis. For some people, this is a selling point. Others might see it as a disadvantage. It all depends on how you want to enjoy your weed.

vaporize cannabis

Vaping cannabis is one of the most convenient ways to use cannabis. It’s not messy. There is no smoke, no ash and no lighter. You don’t have to grind, pack or roll anything. You don’t have to remove the resin from a pipe or bong. It’s also extremely concentrated. You can take a strong hit from a vape and quickly end your smoking session when you have a novel to write or a song to play. You will feel the effects almost immediately.
