Dear Mohammad, I am sure that you have downloaded all reports available at the WHO website.... If you haven't found everything you wanted to obtain, then it seems a good idea to contact the office of non-communicable diseases directly, via email at: [email protected] Likewise, you could contact those involved in the tobacco project at WHO, for example A. Alwana at [email protected] or someone at your local WHO office dealing with tobacco. This could be Y.Song, in case you are studying in the US, [email protected] Usually, if you apporach them with a concise question, they are quite helpful. Hope this assists you a bit in your research, wishing you good success with the further work! SR

Thank you Sibylle Rahlenbeck

I will contact them.
