Are e-cigarettes a good option for smoking cessation?December 2nd, 2013
by Tiffany Zehel, PharmD student
In 2011, an estimated 43.8 million U.S. adults were current cigarette smokers,[i] and currently, estimates of over one billion people worldwide are smokers.[ii] Cigarette smoking is a global epidemic that can give rise to several serious diseases with nearly 6 million deaths annually.[iii] The risk of serious diseases is significantly reduced after one quits smoking and maintains life-long abstinence. Unfortunately many nicotine replacement therapies (NRT’s), such as the patch or gum, have a low efficacy rate in real life practice.[iv] Many studies evaluating the use of nicotine replacement therapies find that while traditional NRT’s provided the chemical need for the individual, the behavioral and psychological needs of the individual were not being met.[v],[vi],[vii]
The electronic cigarette (e-cigarette) was introduced to the U.S. market in 2007 to provide smokers with more freedom to smoke as well as a safer alternative compared to tobacco cigarettes.[viii] The standard e-cigarette is a battery powered electronic nicotine delivery device (ENDD) that resembles a cigarette, and delivers nicotine in a vaporized solution. The acceptance of the e-cigarette is attributed to the similarities of smoking, including the hand-to-mouth repetitive motion and the visual cue of the vapor, addressing the psychological and behavioral aspects of the addiction.[ix]
According to an article published in The Lancet, E-cigarettes were not shown to have a statistically significant difference in individuals that quit. However, they significantly reduced the amount of traditional cigarettes an individual used in a given day compared to the patch.[x] In this news article e-cigarettes are celebrated based on the fact that they show promise to eliminate tobacco smoking completely in the future, but not so much for the promise of helping people break their addiction. Smoking tobacco is very harmful and traditional cigarettes contain toxins that are carcinogenic. In that respect, e-cigarettes should be admired for their ability to replace cigarettes. The issue is that e-cigarettes are not regulated by the FDA like other NRT’s, and their safety has not been extensively researched, due to the recent emergence of the product.
The article also had several limitations. First, the study was underpowered, meaning any effect could have gone undetected, so the results may not be reliable. Another limitation is that there was a high drop out rate in the group given the nicotine patch; this is speculated to be due to the participants wanting to try e-cigarettes but instead where randomly assigned to receive the patch. A third limitation is that the e-cigarette, that this particular study group used, contained less than optimal amounts of nicotine and delivered nicotine inefficiently. As technology advances and e-cigarettes become more efficient in nicotine delivery, e-cigarettes may be proven more effective. The final limitation is that this study was over six months while the amount of time to quit cigarettes can be much longer depending on the individual.x The short amount of time also provided little ability to evaluate adverse effects that the e-cigarette may cause. Due to these obstacles, it is difficult to say whether e-cigarettes would or would not be better than the nicotine patch.
In an article published in the journal of Addiction Science and Clinical Practice (ASCP), a group of people that regularly used e-cigarettes were followed through a forum and interviewed regularly. One repetitive theme in the article was that the subjects, who identified themselves as “vapers,” drew a line between smoking cessation and nicotine cessation. They claimed that they wished to stop smoking because of the health ramifications, but because of the convenience and perceived safety of the e-cigarettes, they had no desire to quit their nicotine addiction.[xi] Up to this point, smoking cessation and nicotine cessation went hand-in-hand. NRT’s were prescribed to step the patient down from their nicotine addiction; currently e-cigarettes are not set up in this way. So now that we have this unique delivery system on our hands, we need to decide if nicotine cessation is as important as smoking cessation. We also need to do further studies on the long-term effects of e-cigarettes to evaluate their benefits over the alternative.
I do not think that replacing one addiction with a modified version of it is the best idea. While it does reduce the health risk, it does not solve the issue of nicotine addiction, the possible long-term effects, and the cost of feeding the addiction. However, I think that e-cigarettes can be beneficial for smoking cessation and nicotine cessation with proper monitoring from healthcare professionals and social support.
Do you think that smoking cessation is more important than nicotine cessation? Do you think e-cigarettes should be utilized for nicotine-cessation?
