"Without a doubt, cigarettes and e-cigarettes are unhealthy and not good for lungs. However, vaping marijuana appears even worse."

New research suggests a link between cadmium exposure and deaths from influenza, pneumonia, and possibly COVID-19.

Scientists once thought ultrasound would never be useful in looking at lung health. An expert explains how new advances are changing that.

People who used e-cigarettes in the past were 21% more likely to develop respiratory disease, and current users had a 43% higher risk, a new study finds.

Few people with severe COVID-19 suffer from unbridled inflammation, researchers report. That suggests anti-inflammatory drugs may not help most patients.

Excess mucus that affects people with cystic fibrosis stick together when compressed. Think of it the same way compressed rice sticks to food to make sushi.

Living human lung air sacs grown in a lab in tiny dishes mimic the real thing. These mini-lungs could accelerate COVID-19 research, scientists report.

Researchers have begun to solve the mystery of how COVID-19 causes "silent hypoxia," where oxygen levels in patients become abnormally—and dangerously—low.

Nickel alloy heating elements in e-cigarette devices may pose more risk for significant lung injury than nicotine, THC, or vitamin E do, a new study shows.

Physical therapy and occupational therapy leads to fewer hospital readmissions and lower death risk for patients with pneumonia, a new study shows.
