Smoking and vaping, steps toward a goal
The most harmful part of a cigarette is the tar and other irritants in each puff of smoke. The addictive part of a cigarette, however, is the nicotine. That is why the majority of cessation aids from gums to patches and lozenges focus on providing the nicotine without all of the other toxic chemicals in a cigarette. What these methods miss, however, is replacing the physical act of smoking.
Enter electronic nicotine delivery systems, more commonly known as e-cigarettes, to fill that need. E-cigarettes work by vaporizing a liquid that is then inhaled; thus the term “vaping” to describe the use of an e-cigarette. The first e-cigarettes became available in the US in 2007 and the most famous brand currently is juul. E-cigarettes are certainly safer than conventional cigarettes. They contain far fewer chemicals and allow you to control the amount of nicotine being inhaled...
For current users, I realize that it may be unrealistic to expect cessation from the beginning, so I encourage smokers to start with smoking moderation and step from there to complete cessation.
That’s where vaping can have a role. Several studies have shown improved lung function in smokers who switched to vaping compared to those who continued smoking regular cigarettes; therefore, for those already smoking, vaping nicotine-only e-cigarettes may be a stepping stone to that goal of complete cessation.
