ScienceDaily (Sep. 8, 2008) — Substances in marijuana show promise for fighting deadly drug-resistant bacterial infections, including so-called "superbugs," without causing the drug's mood-altering effects, scientists in Italy and the United Kingdom are reporting.

To close that gap, researchers tested five major marijuana ingredients termed cannabinoids on different strains of methicillin-resistant Staphylococcus aureus (MRSA), a "superbug" increasingly resistant to antibiotics.
All five substances showed potent germ-killing activity against these drug-resistant strains, as did some synthetic non-natural cannabinoids, they say. The scientists also showed that these substances appear to kill bacteria by different mechanisms than conventional antibiotics, making them more likely to avoid bacterial resistance, the scientists note. At least two of the substances have no known mood-altering effects, suggesting that they could be developed into marijuana-based drugs without causing a "high."
