Popular Vape Flavors Found to Boost Nicotine Reward in Adolescent Mice

UNITED STATES, JUL 18 – Marshall University research shows certain vape flavors trigger addiction-like brain responses in teens without nicotine, highlighting risks of flavored vaping products, study published this month found.

  • On Thursday, the House Study Committee on the Costs and Effects of Smoking held its second hearing since last month, hearing that tobacco companies use social media influencers, bright packaging and fruity flavors to target teenagers.
  • Earlier this month, the preclinical study published in the Journal of Pharmacology and Experimental Therapeutics found that vanilla and cherry flavorings drive reinforcement-related behaviors similar to nicotine exposure, led by researchers at the Marshall University Joan C. Edwards School of Medicine.
  • Researchers tested flavored vapor—including with and without nicotine—on adolescent mice, finding that vanilla flavor alone triggered reward-seeking behavior while cherry did not.
  • Responding to testimony, legislators proposed tougher tax and labeling rules, while Rep. Lee Hawkins called for mandatory ingredient disclosure on vaping product packaging.
  • State lawmakers will meet again to shape vape policy ahead of next year’s session, and the committee is set to reconvene once more before then, with no legislation drafted yet.
