John Daley, Colorado Public Radio | (TNS) KFF Health News G Kumar’s vaping addiction peaked in college at the University of Colorado, when flavored, disposable vapes were taking off. “I’d go through, let’s say, 1,200 puffs in a week,” Kumar said. Vaping became a crutch for them. Like losing a cellphone, losing a vape pen would set off a mad scramble. “It needs to be right next to my head when I fall asleep at night, and then in the morning, I have to thrash through the sheets and pick it up and find it,” Kumar recalled. They got sick often, including catching covid-19 — and vaping through all of it. Kumar, now 24, eventually quit.
