Introduction:
Nicotine-replacement therapy (NRT) and adjunct non-NRT pharmacological treatment are most effective tobacco-control treatments worldwide. Unfortunately, the applicability of these approaches to low- and middle-income countries are limited because of their expenses. According to World Bank information in 1999, there were only 0.4% of smokers in Thailand who could be subsidized NRT (comparing to 25%, 18.5%, 15.6% of smokers in Australia, Finland, and United Kingdom, respectively).

Objectives:
We aim to evaluate abstinence rate after setting up Smart Quit Clinic under resource-limited context without providing NRT.

Methods:
Smart Quit Clinic in Khon Kaen Hospital in Thailand is a program under resource-limited context to help smoking cessation. This program provides individual extensive counseling by specialty trained providers and intensive support, group behavioral therapy, telephone counseling, and minority of non-NRT pharmacological treatment. The primary objective is to find the continuous abstinence rate (CAR) at a 12-month period. Cross sectional study was conducted for 7 months from April to October, 2016. All eligible participants were prospectively follow up until completing the period. Clinical data collection and descriptive statistical analysis were performed.

Results:
The study involved 358 participants, of whom 99.4% were male. About 32.7% of the smokers were between 45-54 years old. Of 32.7% was 11-20 pack-years for a quantification of smoking intensity. About 34.7% of them had 6-7 scores tested with the Fagerström Test for Nicotine Dependence. All participants had attended to various non-pharmacologic strategies in Smart Quit Clinic. Only one-fourth of them received non-NRT with Vernonia cinerea. None of them was accessible for other standard non-NRT and NRT. Remarkably, the 12-month CAR was 43.3%.

Conclusion(s):
Although most of pharmacological strategies for smoking cessation programs are less feasible and less affordable in Thailand, a combination of intensive, specialized care, and behavioral modification provided by Smart Quit Clinic achieved considerably high rates of cessation success.
