It takes a few times to actually get "high". I put it in quotations because the first couple of times you will feel it but not really if that makes sense. Try it with your friend a couple more times to see if you like it.
Also, is the reason you don't like it because it's "bad" for you? There are multiple things that marijuana can help with and there are very very little bad things to come from smoking or eating (edibles) marijuana.
