Weed without tobacco doesn’t get me high

I roll my weed into joints or smoke it up on a water bong. I add tobacco in a ratio, weed : tobacco, 60:40 and it’s pleasant to smoke that way. I have tried rolling joints without adding tobacco, however it feels very coarse and doesn’t get me high. Am I doing something wrong here, because I heard just weed makes you feel good but it’s not true in my case.
