Background:
Article 20 deals with research, surveillance and exchange of information on tobacco products. This paper mandates to update comprehensive information on appropriate scientific national research and established surveillance mechanisms as well as programs that address the magnitude, patterns, determinants, related social, economic and health indicators and consequences of Smokeless Tobacco (SLT) consumption.

Methods:
The present study is a review of global SLT use prevalence among ratified countries. Nationally representative data per country has been collected and validated from respective Global Adult Tobacco Surveys (GATS); Global Youth Tobacco Surveys (GYTS); WHO report on Global Tobacco Epidemic - 2013 & 2015; WHO STEPwsie approach to chronic disease surveillance (STEPS surveys); and Global Progress Report on implementation of the WHO FCTC - 2016.

Results:
Comprehensive information on Global SLT use is limited. Data on SLT use among adults is available at national level in 140 Parties only. Periodic and recent data is available in 15 Parties only. Information of SLT use among adolescents at national level is available for 110 countries only. Periodic and recent data among adolescents is available in 20 Parties. In SEAR, SLT use among adolescents is higher than smoking, unlike other regions. Research on economics and health consequences is available for 25 and 10 Parties respectively.

Conclusions:
Parties should periodically monitor and share the magnitude, patterns, determinants and related social, economic and health consequences of all tobacco products including SLT especially in SEAR.
