Cannabidiol As Antibiotic?

Drug “remarkably effective” at killing range of gram-positive bacteria

New research shows that cannabidiol is effective against Gram-positive bacteria, including Staphyloccocus aureus and Streptococcus pneumoniae, and with a potency akin to such established antibiotics as vancomycin and daptomycin. The research was presented at ASM Microbe, the annual meeting of the American Society for Microbiology.

Researchers from Australia’s University of Queensland’s Institute for Molecular Bioscience's Centre for Superbug Solutions discovered that cannabidiol was “remarkably effective” at killing an assortment of Gram-positive bacteria, including those that have become resistant to other antibiotics. 

Cannabidiol’s inherent antimicrobial activity and its anti-inflammatory potential makes further investigation particularly attractive, according to the researchers.

Of equal importance, the drug retained its activity against bacteria that have become highly resistant to other common antibiotics. Under extended exposure conditions that lead to resistance against vancomycin or daptomycin, cannabidiol did not lose effectiveness. The drug was also effective at disrupting biofilms, a form of bacterial growth that causes infections that are difficult to treat.
