The bill amends the 2015 Tobacco-Free Schools Act, which required schools to be completely tobacco-free, even after school hours.

Stitt signed Senate Bill 33, which prevents people from vaping in schools and on school campuses. The measure also prevents people from vaping in their cars on school property and vaping at school-sponsored events.

Vaping in Oklahoma schools will soon be illegal.

Vaping is the act of inhaling vapor through an e-cigarette or similar device often containing nicotine. The practice has grown in popularity in recent years as many smokers have seen it as a healthier alternative to smoking cigarettes.

Scientists are still studying the long-term health effects, however.

Cartridges for e-cigarettes and other similar devices come in array of flavors, which can make vaping a more palatable alternative to smoking for teens and young adults.

State Sen. J.J. Dossett, the bill’s sponsor, said vaping is an epidemic in every school across the state, and school employees were calling for something to be done.
