"While you certainly can smoke catnip, its effectiveness varies for different people. When smoked catnip is effective, its most common effects include warming throughout the body, a general sense of relaxation and calm, and a sense of mild euphoria sometimes accompanied by giddiness. Inhaling catnip smoke can also bring on physical sensations of minty coolness, which usually spread from the back of the throat to the upper chest and persist for about two hours. Many people report that catnip sedates them and also seems to have anxiolytic action: some users say that smoking catnip helps them find calm after a long day and forget about their worries."
