Sharing is caring!

Anyone else run into issues of mold on their weed before?

I bet you said to yourself, “I’ve smoked worse” and decide to poof away.

Welp, yes, you have probably done worse. But don’t let this trick you into thinking you can smoke mold.

As the legalization of cannabis has become mainstream, it is important for us to also learn about the hidden dangers of this plant. Yes, many people use cannabis as a way to help heal themselves and stay healthy. However, there are risks. If you’re not careful, mold can develop on your plant and ruin the quality of your harvest.

Luckily, there are some steps you can take to make sure that your cannabis is staying fresh and free from mold.

What you need to know about cannabis

One of the biggest dangers of cannabis is that it can be contaminated with mold. So to avoid this, we need to learn what, why and how mold develops on our buds and plants.

Mold Risk When Growing Cannabis

The conditions necessary for mold to develop are dampness, warmth, and darkness. Mold will always grow under these conditions.

Cannabis is very susceptible to contamination because it’s made up of many plant parts that are damp and dark. If you’re not careful, your weed could end up tasting like mildew or smelling like you left it out in the rain all day.

Mold Risk When Curing Cannabis

It’s important to make sure your weed doesn’t get wet during the curing process because it will make it more likely for mold to grow on your dried buds.

Make sure you keep your weed away from any moisture by storing them in a cool dry location like an airtight container or jar with a desiccant packet inside.

Mold Risk When Harvesting Cannabis

The mold spores could also be introduced into your cannabis if you use dirty hands or tools when harvesting, trimming, drying, or storing your weed.

Make sure you wash your hands thoroughly before handling your harvested cannabis so that there is no dirt or grime on your hands to spread onto the plant material during the preparation process.

Why is mold a problem?

When you buy cannabis, it’s important to make sure that the plant is properly dried. This will help prevent mold from growing on your plants. However, there are still some steps you need to take to make sure your plants stay fresh and mold-free.

Mold is a problem because it can change the quality of your harvest. If you’re not careful, mold can develop on your plant and ruin the quality of your harvest.

It’s important to note that if you consume cannabis with mold, it can cause serious side effects like vomiting, nausea, headache, dizziness, difficulty concentrating and more.

It’s also important to know how to protect yourself against mold. Here are some tips:

  1. Make sure your plants are dried evenly so all sides get enough air flow
  2. Always store cannabis in a cool dark place
  3. Try not to handle the plant too much by only harvesting parts of it when necessary

Is it safe to smoke cannabis with mold on it?

Mold is not safe to smoke or ingest in any form, but cannabis with mold on it may be especially dangerous.

Yes, people use cannabis for medicinal purposes and to stay healthy, but many don’t realize that if their cannabis has mold on it, the mold can actually cause health problems.

Some of the most common symptoms of mold exposure are watery eyes, coughing, chest congestion, nausea, vomiting and difficulty breathing. All of these symptoms are bad for you in general-but they may be even worse when combined with cannabis because it increases your risk for respiratory illnesses.

If you have any of these symptoms after smoking cannabis with mold on it, stop immediately and contact a doctor.

How do you prevent mold from developing on your plant?

Mold starts to form on cannabis when the plant is exposed to bad air quality. The cannabis needs to be kept in a dry, dark environment until it’s ready to be harvested. If it becomes wet, mold can develop on your plant and ruin your entire crop.

There are several steps you can take to avoid this from happening. First, make sure you have an adequate ventilation system installed in your grow room. This will help increase the air circulation in your grow room and minimize moisture levels, both of which are important for preventing mold from developing on your plant.

Next, make sure that the temperature inside of your grow room is within recommended temperature ranges of 68-82 degrees Fahrenheit. It needs to stay at a cool temperature so that mold does not start growing on your plant while it’s still in the growth stage.

Also, try to keep your humidity levels under 50%. If they get too high then mold will grow more quickly on your plants because the air will become wetter and more humid.

Finally, make sure you clean up any spilled water or excess moisture around the area where you store your cannabis before it has time to dry up and cause any excess spores or molds growths near where you store them.


It is important to understand the risks of mold and how to prevent it from growing on your cannabis. Once you have the knowledge it will be easier to make decisions about what to do with your plant.

Avoid mold at all costs.

Stay safe out there and stay groovy.
