Cigarette Smoke Makes Superbugs More Aggressive

In lab and mouse experiments, cigarette smoke helps drug-resistant bacteria fight off the immune system —

Methicillin-resistant Staphylococcus aureus (MRSA), an antibiotic-resistant superbug, can cause life-threatening skin, bloodstream and surgical site infections or pneumonia.
