Researchers Investigate CBD as Answer to Antibiotic Resistance

Scientists from the Institute for Molecular Bioscience at The University of Queensland say that CBD (cannabidiol) may be an effective weapon in the fight against antibiotic resistance. The team tested CBD samples against certain staphylococcus strains that cause skin infections, and streptococcus, the cause of strep throat. They compared the efficacy of CBD to that of vancomycin and daptomycin, commonly prescribed antibiotics. According to Mark Blaskovich, Ph.D., senior research officer at the Centre for Superbug Solutions, “We looked at how quickly the CBD killed the bacteria. It’s quite fast, within 3 hours, which is pretty good. Vancomycin kills over 6–8 hours.”

The study also showed that the CBD: 1) disrupted the bacteria’s biofilm, 2) is not as likely as existing antibiotics to cause resistance, and 3) was effective against gram-positive but not gram-negative bacteria.

Findings from another study showed that topical CBD used to treat skin infection in mice reduced bacterial levels after 48 hours but did not eliminate the infection. The researchers are continuing their work.
