Smoking catnip may not be the primary use of this herb, but it does have certain effects on the body you should know about before trying it.
What is Catnip?
Catnip scientifically known as Nepeta catariais an herbaceous plant in the mint family that has a range of effects on humans and other animals and can be consumed in a variety of ways. Sometimes referred to as “kitty pot”, catswort or field balm, it can create a sense of relaxation, pleasure, and giddiness in animals, and apparently, can also affect humans in a similar way. 
Catnip has been used for thousands of years for teas and tinctures, and people have also been smoking it, similar to smoking cannabis, white sage or mugwort, among others. Nepetalactone is the active ingredient, which intoxicates cats and sedates humans. While there is some debate as to whether smoking this herb is an effective anxiolytic or psychoactive treatment, anecdotal evidence points to various surprising benefits.
