back in the day i would mix other herbs into my "herb" to stretch it and for extra effects. catnip was one of them. ( it does more than u think it does really) i had to quit using it tho... my cat would NOT leave me alone while i was smoking it. she would chase the smoke around on the couch until she was dizzy and high as a kite, then flop somewhere and purr for an hour. even after i quit the 'nip she would still come running when she smeeled the MJ come out in hopes. had to start smoking it only in the bathroom so poor kitty didnt get that into her system
