BUFFALO, N.Y. — Researchers at Roswell Park Comprehensive Cancer Center are among those nationwide studying the impact of electronic cigarettes on people's health.

2 On Your Side spoke with a doctor at Roswell Park, who just had a paper published on vaping-induced severe respiratory diseases.

Doctor Yasmin Thanavala says while a majority of cases have been tied to people vaping THC that's not the case in all patients. So it's far too early to call the exact cause of these illnesses.

"About 80% of the cases they say they have also vaped CBD or THC, and some say they have vaped both," Thanavala said. "So that leads to also the uncertainty as to what is the commonality that is causing this."

Roswell Park doctors also advise young people not to vape until the health risks are fully researched.
