Vaping Better at Helping Smokers Quit, Study Finds

ADELAIDE, AUSTRALIA, JUL 14 – An eight-week clinical trial in Adelaide showed 28% of participants who vaped remained cigarette-free after six months, aiding smokers who struggled to quit for years.

  • Researchers led by Ryan Courtney conducted a randomized clinical trial between March 2021 and December 2022 in New South Wales, Australia, assessing 1,045 low-SES adult smokers receiving government support and willing to quit smoking.
  • The trial randomly assigned participants to an eight-week supply of vaporized nicotine products or nicotine replacement therapy , aiming to compare six-month continuous smoking abstinence rates between groups.
  • Results showed more than 28% of participants using VNPs remained smoke-free after six months, compared to about 9.6% in the NRT group, with follow-up data collected at seven months.
  • Courtney explained that vaping devices can provide nicotine in stronger doses with a smoother sensation and more appealing taste. He also noted that 58% of individuals who started vaping continued to do so after six months, highlighting the importance of supporting users in quitting not only smoking but also vaping.
  • The study suggests VNPs have superior effectiveness for smoking cessation among disadvantaged smokers but calls for further research on long-term abstinence and the health impact of vaping.
