There is nothing wrong with "Addicted in Afghanistan" but it is not a sentence. It might be a newspaper headline or the caption under a photograph. It will be a shortened version of something else. For example, if it is a photograph of a drug addict in that country, then the headline would be a version of "This man is addicted to drugs and is in Afghanistan". As you can imagine, that is too long to put under a photo so the relevant terms are taken out and used alone. The relevant words are "Addicted" and "in Afghanistan". That actually tells you everything you need to know.
