When I give it to my cat, he appears to be very strongly affected by it. He will stare at things, get extremely hyper, and generally act as though he is extremely high. While going through a very druggish phase in my late teens, I ate large amounts of catnip hoping to have similar effects that the cat was experiencing. Of course, that didn't happen. It affects humans completely differently. I did notice extremely strong sedative effects. While falling asleep, the quality of 'sleep' was distinctly different from normal. Then, after being quite depressed and dealing with various issues, I decided to give it another try. I chewed a small amount of it, which tasted awful. I chewed it thoroughly, and had very limited expectations for what it was going to do. I hoped that maybe it would help me to feel better. To my surprise, this time it felt as though IT DID have an affect. For the first time, I felt completely rational and fully was able to trust my thinking I felt very insightful and also music definitely sounded a bit better. I also had much more energy and the sluggish quality I had before was gone completely. A couple of pinches, well chewed seemed to work wonders for me. I have tried it a few times, and it seems effective. Of course, it may be placebo, but part of me thinks not. Has anyone else had experiences with catnip? If so, was it effective? I have heard it is quite safe and some people use it every day!
