I can’t get drunk at all

Hello, I’m 20 and have been drinking and partying since I was 17. During all this time I’ve never been able to get drunk no matter what I’ve done. At one time I drank a half of bottle of titos and nothing ever happened. I only ever feel a little loose but never drunk. Im able to get high when I some weed and do shrooms but never get drunk. I was wondering if anyone knew what was wrong, cause I can’t seem to figure it out when I look it up.
