The average person can’t be bothered to clean up their own mess, but many have discovered that cleaning up mold on weed can be an important part of keeping the plants healthy.

A new study out of the University of Arizona finds that mold on marijuana can be a source of disease, and the researchers say it could be a real problem.

“Mold can be used to grow fungi, bacteria and viruses,” said Dr. James C. Leung, the study’s senior author.

“So there are potentially significant health consequences from mold exposure.”

Researchers looked at mold in the urine of 30 participants who had been using weed recreationally for at least one year.

The subjects were then asked to take a series of measurements, including whether they had had moldy weed or not, how often they had used it, and how often during the past year they had cleaned their own surfaces.

“The more frequent the mold exposure was, the higher the prevalence of mold in urine samples,” said Leung.

“It could mean that marijuana users are more likely to have moldy urine samples, and they’re also more likely if they’re using it recreationally, they’re more likely they’re going to have more mold in their urine.”

Mold is a common problem in the United States, with an estimated one in five adults reporting some form of mold, according to the Centers for Disease Control and Prevention.

“When mold is present, it can affect the way we think about ourselves, our ability to function, and our ability not to have a bad day,” Leung said.

Mold may also be a contributor to asthma, since mold can cause respiratory problems, including shortness of breath, shortness and wheezing, as well as coughing and wheeze.

Marijuana can also damage your lungs, which is why it’s important to be aware of mold and the risks it can pose.

Leung said mold and asthma are common problems for the American people, but mold exposure has increased in recent years due to the rise of medical marijuana.

“Medical marijuana is not the only source of mold exposure.

It is a significant source of the mold problem,” he said.”

If you’re not careful about mold, you could get a very serious respiratory illness like asthma.”

Leung and his colleagues hope their findings will help researchers identify ways to prevent mold on medical marijuana patients, but they’re not yet ready to recommend a treatment.
