A recent study has shown that CBD has potential as a future super antibiotic. The research was conducted in Australia at the University of Queensland’s Institute for Molecular Bioscience’s Centre for Superbug Solutions. (UQIMBCS)

The scientists found CBD (cannabidiol) killed all the strains of bacteria they tested in a lab. That includes some superbugs that are highly resistant to antibiotics. And get this. The study found that even after 20 days the superbug bacteria were unable to become resistant to the CBD treatment.

“We still don’t know how it works, and it may have a unique mechanism of action given it works against bacteria that have become resistant to other antibiotics, but we still don’t know how.”

Here’s how the study was conducted.

The study tested a group of bacteria including the dreaded bug MRSA (the dreaded hospital superbug), Streptococcus pneumoniae (leads to pneumonia), and E. faecalis (can kill people with weak immune systems).

Researchers also treated lab rats for skin infections and found the CBD was effective. This means CBD as a super antibiotic in the future is a real possibility. So far, they’ve only demonstrated it’s healing properties as a topical application (applied to the skin). The next step would be to test CBD as an oral application (by mouth) or through an IV (intravenous).

It should be noted that this research was conducted with synthetic CBD. The Australian government strictly regulates cannabis.

“The most challenging part [of the study] was getting the correct permits to handle cannabidiol in our laboratories, as the Queensland government regulates who can use/handle it—even though the material we are using is completely synthetic, it falls into this grey area under the definitions of cannabinoids.”

A note of caution about CBD as a super antibiotic.

This study isn’t peer-reviewed. Now, while the news is encouraging and warrants more research, it’s not a reason for anyone to abandon their prescribed antibiotics. The results were positive news for the treatment of Gram-positive bacteria. It’s not effective against Gram-negative bacteria. So, please make sure to talk to your doctor if you are thinking of adding CBD to your treatment plan for a skin infection.

CBD may one day be the super antibiotic that kills all superbugs, but we aren’t there yet. Stay healthy and stay safe.
