A father is urging parents to take vaping dangers seriously after his 17-year-old daughter suffered a life-threatening lung collapse linked to extreme nicotine use.

Mark Blight rushed his daughter Kyla to the hospital after learning she had collapsed during a sleepover and had turned blue. Doctors later revealed she was close to cardiac arrest. She needed an emergency operation lasting more than five hours, during which surgeons removed part of her lung.

Medical staff found a ruptured pulmonary bleb — a small air blister at the top of the lung. They believe her intense vaping habit caused it to burst. Kyla started vaping at 15 and regularly used 4,000-puff disposable vapes each week, roughly equal to smoking 400 cigarettes.

She spent two additional weeks in the hospital recovering and now says she will never touch vapes again.

Her father, who lives in Cumbria, shared her story to warn other families. He said the damage was “terrifying” to witness and believes disposable vapes played a direct role. He also noted that doctors are seeing more young people with similar lung injuries.

Kyla says she began vaping because “everyone at school was doing it” and believed it was harmless. The ordeal changed her mind. “I won’t go near them now,” she said. “It scared me to death.”

Health experts continue to warn that, while vaping is often viewed as safer than smoking, the long-term effects remain unclear — especially for children and teens.
