We are very grateful to Singh and Chaturvedi[1] and Priya et al.[2] for their interest in our systematic review on the application of augmented and virtual reality (VR) in cigarette smoking cessation.[3] I would like to respond to their questions and comments.

It is widely accepted that in the current COVID-19 pandemic situation, most of the healthcare interventions are being switched to the virtual platform. Similarly, numerous studies have explored the possible use of augmented reality (AR) and VR-based applications for tobacco cessation. In a cross-sectional study by our team, we attempted to determine the suitability of VR for simulating smoking among current cigarette smokers.[4] Key inferences from our study were as follows: (a) When current cigarette smokers were repeatedly exposed to smoking cues through cue exposure therapy it led to a significant benefit in smoking cessation. (b) When the smokers were exposed repeatedly to the virtual cues, the relapse rate was minimal. The cue used in our study was a burning cigarette and the differentiation between normal lungs and those of cigarette smokers. The movement of the cigarette in the video was such that it increased the realism of the VR-smoking environment.[4]

VR provides more attention, visual balance, and coordinated movement, but the major difference while using this as compared to the traditional methods is that it provides a realistic experience. The limitations include an inability to ascertain variations in the levels of nicotine addiction and the fact that the study population was limited to a particular area.[4] In AR, it is hypothesized that if the potential images are rather neutral and those which elicit smoking urges can be avoided, a better result can be anticipated. However, a study should be conducted towards this end to add strength to this hypothesis.

While successful smoking cessation programs have been established, the success of smoking relapse prevention strategies has been limited. A high relapse rate has been observed in cognitive behavioral therapy (CBT) in particular. VR exposure therapy can create artificial environments that simulate risk circumstances for the patient in the context of relapse prevention because relapses might be caused by the presence of conditions associated with tobacco intake like drinking in bars with friends, having dinner with avatars smoking on the terrace of a restaurant, waiting at a bus stop with avatars smoking, taking a break in the workplace or studying with colleagues who are smokers. These conditions can also increase the risk for smoking.[5] Therefore, additional studies are needed to make meaningful conclusions about the relapse rate for smoking cessation.

We are planning to conduct a longitudinal study to determine the usefulness of applying these concepts to smoking cessation. However, a detailed discussion of this study would be beyond the scope of the present letter.

Considering the above points, we conclude that VR and AR have a great potential to provide additional benefits to CBT and pharmacological therapies in tobacco cessation and need to be explored.
