A study has found that vaping at normal power levels poses virtually no cancer risk from inhaling the smoke. The study was published in the journal Tobacco Control last week.
Professor William Stephens of the University of St Andrews in Scotland, used conventional exhaust gas analysis to measure the carcinogenicity of vape , heat-not-burn and regular tobacco smoke. He devised a way to equate these indices into the same units for the most accurate comparison.
Although he explains that vaping at too high a power (enough to cause dry hits) will produce high levels of aldehydes, when used properly, e-cigarettes pose only 1% of the cancer risk of cigarettes. In fact, vaping is as low as nicotine replacement therapy (NRT) like nicotine gum and patches.
“This study should dispel any lingering doubts in tobacco control plans about whether vaping actually reduces health risks,” said Boston University Professor Michael Siegel. “Many anti-tobacco groups and health agencies have repeatedly claimed that vaping is no less harmful than smoking, but that claim is false, and the current study adds significant weight to the already strong evidence that vaping is much safer than smoking.
Professor Glantz: Who cares about cancer?
Congratulations to Professor Stanton Glantz of the University of California-San Francisco for acknowledging the existence of this encouraging research. Shame on him for misleading his blog readers by deliberately hiding this good news and posting what he believes to be true.
“This analysis ignores that cancer accounts for only about one-third of tobacco-related deaths,” Glantz wrote. “Most of these deaths are due to cardiovascular disease and non-cancer lung disease. Current evidence suggests that e-cigarettes pose a significant risk for these outcomes, especially given the fine particles they emit.”
“Any consideration of e-cigarettes needs to consider the impact on the entire population, especially how they expand the nicotine market by attracting children and discouraging adults from quitting.”
Microparticles are the cause of heart disease in tobacco smoke because they are solid and are formed from burning fuel. Vapor smoke is liquid and is absorbed by tissues in the larynx, esophagus and lungs. There is no evidence that liquid particles cause blockages in the lungs and blood vessels like solid particles.
But that was the hypothesis Professor Glantz had asserted and pursued, even though no other scientists had confirmed the “danger.” No one had even touched on the issue except the health authorities and politicians who regularly spoke to him and his subordinates at UCSF.
His claim that vaping “makes it harder for adults to quit smoking” comes from a 2016 analysis of his e-cigarette theory. This hypothesis has been refuted by many other professors (Ann McNeill and Peter Hajek, Clive Bates, and Carl Phillips).
Professor Konstantinos Farsalinos responded to Glantz’s blog post. “This statement is not only unethical, but also completely unscientific, contrary to most of the available data,” the cardiologist wrote.
Weeks of good news for vapers
The last weeks of July brought a lot of good news for American vapers, and a lot of good news in a record short period of time. The FDA extended the PMTA until 2022, and decided to take a more objective look at the issues of nicotine, tobacco, and vaping. High-quality studies with data confirm that vaping really does help smokers quit. Vapers gathered enough signatures to challenge the San Francisco flavored e-liquid ban.
And now we have evidence that the most dangerous thing about smoking is not present in vaping. It’s been a good few weeks, and hopefully this positive news will spread to India and Australia, which are facing many challenges.
