Huge study hints at risks of switching from tobacco cigarettes to vapes

Nature, Published online: 14 June 2026; doi:10.1038/d41586-026-01834-9 Lung cancer risk was higher in people who took up electronic cigarettes than in those who quit smoking completely.

Why this matters
Why now

Why it’s important

This research undermines the public health narrative that vaping is a significantly safer alternative to traditional cigarettes, potentially influencing regulation and consumer behavior.

What changes

The perceived relative safety and health benefits of electronic cigarettes compared to cessation are diminished, prompting a reassessment by public health bodies and consumers.
