One-third of people who use e-cigarettes report having one or more symptoms of vaping-related lung injury, according to a new study.

These symptoms include cough, shortness of breath, nausea, stomach pain and chest pain, HealthDay reports.

Symptoms were less common in people who used disposable e-cigarettes, researchers from Northwestern University Feinberg School of Medicine in Chicago reported. People were 70% more likely to report symptoms if they used devices refilled by pouring in more e-liquid. They were 95% more likely to report symptoms if they used devices with refillable cartridges.

The findings are scheduled to be presented at an online American Heart Association meeting.
