The study found that the antismoking medication varenicline can increase rates of smoking abstinence without causing serious adverse events.
In their work “Respiratory health effects of e-cigarette substitution for tobacco cigarettes: a systematic review”, researchers analyzed 16 studies from 20 publications: most of the studies showed no difference in respiratory parameters. This indicates that electronic nicotine delivery systems substitution for smoking likely does not result in additional harm to respiratory health.
Replica researchers performed a standard toxicology battery of three assays used for product assessment and regulatory applications.
According the authors, for every 100 people, 10 to 19 are likely to quit using an e-cigarette; 12 to 16 using varenicline; and 10 to 18 using cytisine. This is compared to the 6 in 100 people likely to quit when using no medicine/e-cigarette or placebo. People using two forms of nicotine replacement therapy at the same time, for example, a combination of nicotine patch and nicotine gum, seemed to have similar rates of quitting to people using e-cigarettes, varenicline and cytisine.
According to prof. Riccardo Polosa, CoEHAR founder: "This small qualitative research simply found what we already knew: that young people are eager to explore new experiences, with vaping potentially being one of them. A critical limitation of this research is the absence of insights into how these participants have been educated about the health implications and addictive nature of nicotine/vaping. To work towards a smoke-free world, it's essential that our messaging on vaping's risk-to-benefit ratio is both accurate and truthful"
"We read with interest the proposed draft bill and we are appreciative of the key contributions this Bill will make in relation to the contrast of tobacco smoking. However, we are concerned that the current draft will restrict less risky options for people who would benefit from using these products to quit smoking. Bringing regulatory parity between cigarettes and non-combustible alternatives (like e-cigarettes, heated tobacco products, oral nicotine/tobacco pouches) will further discourage smokers from trying alternatives – something that should be actively encouraged given that South Africa has high smoking prevalence and low successful quitting rate"
86% of physicians believe that combustion is more harmful than nicotine. 64%-77% of physicians believe that nicotine directly causes various smoking-related conditions, with 19% to 32% believing strongly.
A panel of tobacco control experts, including Dr. Sudhanshu Patwardhan, Dr. Riccardo Polosa, and Dr. Jed Rose, discuss their views on how the survey results might impact smoking cessation and tobacco harm reduction efforts.
While an average of 87% of doctors at least moderately agree helping patients quit smoking is a priority, it is troubling that on average 74% mistakenly believe nicotine causes a range of illnesses from lung cancer to COPD.
