Vaping-related illnesses and deaths have spurred more young people to seek help to quit, physicians and psychologists treating teenage users of e-cigarettes say, but few treatment options exist and there is rising concern that the public-health response for cessation programs is inadequate.

Jonathan Avery, director of addiction psychiatry at Weill Cornell Medicine in Manhattan, said many teen e-cigarette users have been arriving at his hospital’s emergency department in recent weeks with what they believe are complications from vaping.

In some cases, teens are catching early symptoms of vaping-related lung illnesses, he said, but in others, it is nothing medical—teens are afraid they might be sick.

These patients, and others, are now eagerly wanting to quit. Those who have stopped vaping are flooding his office with calls on how to maintain abstinence, he said.

“I don’t see so much the kids unwilling to quit at all. Now the kid and the parent are both on board with quitting,” Dr. Avery said. “What’s missing is a youth nicotine treatment center.”
