Let's say there is a specific paper that I'm having trouble understanding. Perhaps it's out of my field, or perhaps not. Is it suitable to the purpose of this StackExchange site that I could post a question asking about the paper? Or is this Academia site not intended for within-field or paper-specific questions?
If the latter, is there another field-agnostic StackExchange site which does accept such questions, or should I seek out a field-specific StackExchange site for such a question?
Tangentially, I'm trying to understand if this paper suggests that nicotene triggers a relaxation response, which might indicate health benefits that other nicotene studies neglect. Feel free to comment about it, but don't include that in an answer please.
