The researchers also couldn’t determine the source of the subjects’ fungal infections, so it’s impossible to say if cannabis use caused them.
Indeed, 43% of cannabis users who had fungal infections were immunocompromised, and 40% of cannabis users who had fungal infections were hospitalized upon their diagnosis because of the severity of their conditions.
The researchers said that marginally increased risk is still cause for concern because of the potentially deadly nature of fungal and mold infections, and existing evidence that cannabis is susceptible to fungus growth.
For normally healthy people, a fungal infection can lead to a rash, allergies, or asthma, but in more severe instances, it can cause pneumonia, meningitis, and bloodstream infections.
“In this large commercially insured population in the United States, cannabis use was associated
with a higher prevalence of certain fungal infections,” the researchers wrote.
A government report warns that cannabis could cause deadly infections, not from the smoke it creates, but from fungus and mold that grow on the plant’s flowers.
If people want to continue using cannabis but worry about fungus and mold content, they should ask budtenders at dispensaries to provide testing documentation, Donald Land, chief scientific consultant at cannabis and tech firm Steep Hill, previously told Business Insider.
The study, published on May 13 by the US Centers for Disease Control and Prevention, builds on previous research in California and Colorado that found legal marijuana was contaminated with pesticides and mold, and could pose a risk to people prescribed marijuana for medical conditions.
There were caveats to the study. They relied on self-reported claims about cannabis use, which could have skewed their findings.
People who use cannabis and are immunocompromised could be at risk for deadly complications like pneumonia, according to the CDC-backed study.
If your plants do end up getting infected you’ll need to fully disinfect your growing area once you’ve harvested. The next few times you grow in this spot you’ll need to treat them with preventive products and fungicides such as propolis. Keep in mind that mildew spores can stick around for up to two full years before dying off, so you’ll need to protect your plants during that entire time.
Fertilizers rich in silicon reinforce your plants’ structure and cell walls, especially on the leaves, making it much easier for fungi to get to them.
One of the most important factors is how healthy your plants are – the more stressed and unhealthy they are, the more likely they are to become infected by fungi. Healthier plants are a lot less likely to become infected.
Excessive water can also cause fungi to appear, especially if you haven’t used any clay in your substrate which helps to filter extra water. This tends to happen when people flush out their plants’ roots by watering way too much until the water comes out the bottom. This, plus the fact that it’s your plants’ last few days, makes for a sure-fire recipe for fungi in your plants, especially if their flowers are quite dense.
Pythium is a kind of fungi that grows in your plants’ roots, impeding your plants from feeding properly. This fungus essentially weakens your plants’ roots until they eventually kill them completely. It can appear in plants of all ages and sizes, although younger plants are the weakest. Its spores are transported via contact and can even be brought to your plants via the soles of your shoes.
Fungi are microorganisms that generally live on/off other organisms such as animals, food and many, many kinds of plants. Today we’re going to talk about different types of fungi that can infest cannabis plants and how to get rid of them; keep your plants healthy and stable without losing any of your quality flowers.
Over the last few years this fungi has been found in increasing quantities in outdoor crops, especially in extremely humid areas which need to be sprayed with fungicide if you plan on growing there.
In order to detect this fungus you’ll need to keep a careful eye on your plant, as it’ll cause them to be super weak and show many deficiencies due to the deterioration of its roots. In systems where the roots are exposed such as hydroponics or aeroponics you’ll be able to see them change color to dark brown or even red on occasion.
Rust is one of the fastest-spreading fungi, as it gets into your plants’ skin and is incredibly easy for your plant to absorb. It shows up as yellow/orange stains on your plants’ leaves, starting on the tops of the leaves which is why sometimes it’s confused with nutrient deficiencies. Once the fungi has taken over your plants, the underside of the leaves will also begin showing red and brown dots, and the rest of the plant will start becoming deformed.
In this article we're going to explain the types of fungi that can infect cannabis plants and the best way to get rid of them.
