mogencho Reviewed by mogencho on . Calling All Doctors Well I guess it doesn't have to be doctors. I enjoy smoking joints (what can i say...) and live on a college campus. I have been testing various ways of covering up the smell so I can walk around campus without worrying about having an offensive odor following me around and tipping off people. The best solution I've found is to mix a dab of clove powder (<1/8 t) per joint. This covers up the smell nearly 100% and makes its smell like a clove cigarette (with no tobacco!).
