A study revealed that switching to e-cigarettes could have avoided up to 6.6 million premature deaths in America. However, using low rather than high nicotines may potentially increase the risk of exposure to toxins in the vapor as they may be using their device more intensely.
Public Health England suggests that e-cigarettes are a “lower-risk alternative” to tobacco and could help smokers to quit. The new research suggests that smokers who want to switch are better to start with higher, rather than lower, nicotine levels to reduce compensatory behavior and the amount of e-liquid used.
To accomplish the findings, researchers at London South Bank University studied 20 e-cigarette users and discovered that those who use low nicotine e-liquid in their devices puffed often than those who use high nicotine liquid. The evidence is similar to many existing reports which implied that smokers inhale low-yield cigarette smoke more deeply than that of high-yield cigarettes.
Despite the “compensatory” behavior of the users of low nicotine e-cigarettes, they were unable to get as much nicotine as the high nicotine group. However, using low nicotine e-cigarettes may not be helpful since their puffing behavior may increase their exposure to toxins such as formaldehyde, a chemical formed when an e-cigarette is heated.
Furthermore, deep inhalers and those puffing on a cigarette have higher risks of laryngeal cancer, a previous study discovered. The same research suggests that changing inhalation habits might be the first step to reducing the risk of developing laryngeal cancer.
Vaping more intensely and deeper raises the temperature inside e-cigarettes which can cause the glycerine and glycol found in most e-liquids to break down. The event increases the risk of the user to chemicals. Although the exposure is still at far lower levels than with smoking, it should be minimized where possible.
The low nicotine group in the study also reported a stronger urge to vape, more acute withdrawal symptoms and were less satisfied after use.
The study’s findings are similar to the evidence on using nicotine replacement therapy (NRT) that shows smokers will reduce cravings when given a sufficiently high dose of nicotine that will increase their chances of successfully giving up tobacco.
“Let’s be clear. While there are potentially harmful chemicals present in the e-cigarette vapor, there are far more in tobacco smoke. The best thing smokers can do for their health is to stop smoking, and switching to e-cigarettes is one way to do this,” Alison Cox, director of prevention at Cancer Research UK, concluded.
