[What's the impact of illicit tobacco trade on international economy?]

I could have simply put it in a way that you'd appreciate: "Hey guys, so I'm working in a tobacco industry and participated in a conference about illicit trade and there was a question from an audience about its impact on international trade. The presenter didn't make much of it. What do you think?"

 

Yes, this is an academy related thing. However, i came up with the topic myself only seeing the first aspect of the impact that i mentioned. After researching a bit on the topic I wasn't able to find if it has such big effect on the international trade itself (which is my target). If you don't like it at least provide me with a link to another forum.

For me it is very clear that illicit tobacco trade directly affects county's economy by skipping the taxation process of such products. However, here it only impacts countries separately. 
Please tell me how illicit tobacco trade plays on the whole international economy? How it affects international trade? I'd appreciate examples. Thank you!
