Study on the safety of electronic smoke is a 113-page report published by the Public Health Agency (PHE) in August 2015. E-cigarettes are a safer way to replace traditional tobacco, the report said. E-cigarettes: an Evidence Update. The report summarizes current research, arguing that e-cigarettes are about 95 percent less harmful than traditional tobacco and are expected to be used as an alternative to tobacco withdrawal drugs such as nicotine patches.
The Royal College of Physicians published a 200-page study in April 2016, titled Nicotine without Smoke: Tobacco harm reduction (Smoke-free Nicotine: Reducing tobacco hazards). The results of the study support the following conclusions: 1. E-cigarettes are not the gateway to smoking; 2. E-cigarettes do not lead to the normalization of smoking; 3. E-cigarettes are a great help in quitting smoking; 4.The long-term harm of e-cigarettes may be less than 5 percent compared to other tobacco products.
An internationally renowned e-cigarette researcher, Dr. Farsalinos, said that the main source of e-nicotinic substances is dry burning in the use of e-cigarettes and the PG/VG of tobacco and oil components, and that VG will release more aldehydes than PG.
A study published in January 2017 in PLOS ONE, led by Dr. Wang and funded internally by the California Department of Public Health, concluded that the heating temperature of e-cigarettes had a significant impact on the level of aldehyde substances released by PG/VG.
The above information indicates that e-cigarettes are at least 95 percent safer than traditional cigarettes, and that smokers physically smoke to obtain nicotine. But the safety of e-cigarettes is only for traditional smokers; it is not completely harmless in itself. This 5 percent of health risks needs more scientific research results, and the industry in the product itself on the rational innovation to avoid. E-cigarettes provide a safer and healthier way for smokers to replace traditional cigarettes, which is of great benefit to smokers.
