Effect of the E-Cigarette on Nicotine Cravings and Withdrawals Symptons


One frequent criticism of the electronic cigarette is that there has been no proof that it can work as a smoking cessation aid. Most suppliers do not now market the electronic cigarette as a cessation aid, due to legal reasons, but there has been research into the extent to which the electronic cigarette can satisfy cravings. This page aims to summarise that ressearch.

Research Aims

The Electronic Cigarette research in New Zealand, again sponsored by Ruyan and Health New Zealand, aimed to test on the ability of the electronic cigarette to relieve nicotine cravings and withdrawal symptons.

The Research

To test the effectiveness of the electronic cicgarette, the researchers compared the device to:

  • cigarettes
  • a placebo (an electronic cigarette with zero nicotine cartridges
  • Nicorette® nicotine inhalator0mg 16mg inhalator

40 cigarette smokers used the devices after a night's abstinance. Their craving relief was rated and the nicotine levels of nine of the participants was also rated.


- Participants using the a 16mg electronic cigarette experienced significantly less cravings than those using an electronic cigarette.

- The electronic cigarette rated slightly above the nicorette inhaler for reducing irritability, restlessnes, poor concentration and the need for a cigarette.

- The electronic cigarette had fewer adverse effects than the inhaler.

- The electronic cigarette delivered nicotine more quickly than the inhaler, but not as quickly as cigarettes.

- The electronic cigarette delivered the smallest amount of nicotine - almost one tenth that of cigarettes.


The researchers concluded that the device showed promise as a nicotine cessation aid, but that further research was needed.
