Smoke, not nicotine, causes deaths, health expert says

Inhalation of smoke, not nicotine, is the culprit that causes smoking related deaths and diseases according to a Canadian health expert.

“The nicotine itself is not the problem. The global health catastrophe we face is due to the way it’s delivered. In short, for anyone wishing to tackle the global toll of 20,000 lives a day lost due to cigarette smoking, we need to remember just four words: ‘it’s the smoke, stupid’,” Prof. David T. Sweanor, chair of the advisory board of the Centre for Health Law, Policy & Ethics at the University of Ottawa said.

He stressed that contrary to popular belief, nicotine is not the substance that causes these deaths.

“There have been many decades of research on the health effects of cigarette smoking, and we have known since at least the 1970s that the primary cause of the cancers, heart and lung disease is the repeated inhalation of smoke,” he said.

The professor made the distinction to differentiate the risk profile of non-combustible alternatives (NCAs) like vapes, heated tobacco products (HTPs) and oral products like Sweden’s snus which deliver nicotine without burning tobacco.

He said by eliminating combustion or the burning process, these innovative products provide smokers less harmful alternatives to smoking.

Sweanor said the human body is simply not designed to inhale smoke. It is the tar from combustion, and not nicotine, that contains carcinogens and toxicants.

“We see similar disease patterns in those who cook food over open fires with poor ventilation and in firefighters exposed long-term to smoke inhalation,” he said.

He likened nicotine to caffeine, saying it is a psychoactive substance that is addictive and gives assorted benefits to many users. He, however, noted that “by themselves, neither have significant health risks when used at normal dosage levels. But if obtained through a toxic delivery system such as smoking, great injury can be caused.”

Sweanor said that making NCAs available to countries such as the Philippines will help millions of smokers reduce their exposure to smoke and illnesses. (PR)
