Its sorta like a way of asking if you can get any/have any on you. I often got asked if I was stoned.. lack of sleep often makes my eyes bloodshot which is usually what happens when I get high. Once though, I was actually high, and these dudes who I'd never met before asked me and my mate if we were stoned.. we were, n ended up sparking one up with these random people hahaha
good times.
