How much does your trust (or distrust) of the readers comprehension affect how you write and your word choice? For example, the above passage is a snippet from Rain When I Die. Where I used the word "syringe" I actually want to use the word "needle" but for some reason I don't trust the reader will understand it's a used heroin needle and not a sewing needle. Why is that? Should I be more trusting of peoples ability to get the gist of what the narrator is saying?
