CATNIP Side Effects & Safety. Catnip is POSSIBLY SAFE for most adults when taken by mouth in small amounts. Cupful amounts of catnip tea have been consumed without serious side effects. However, catnip is POSSIBLY UNSAFE when smoked or taken by mouth in high doses (many cups of catnip tea, for example). It can cause headaches, vomiting, and a feeling of being ill. Not enough is known about the safety of applying catnip directly to the skin.
