How to deal with our aversions & judgements?

There’s one issue that seems to be very divisive in my conversations. And I realize that it is because of me and my own aversion & anxiety. I have done drugs. But one drug that always bothered me since I was young was cocaine. My father abandoned my mother when I was young and was very much involved with it as an abuser and a seller. For this reason I was always sure to not use it. I’ve been around it a few times & each time I get extremely uncomfortable. Not only that, but when somebody close to me talks about it in a nonchalant way, it tends to make me so uncomfortable that I can’t help but get defensive & agitated. I feel very hypocritical because I have done other drugs like acid and mushrooms and feel no aversion to that. And I feel like I am being very judgemental in my reactionary ways when it is discussed. Is there any Buddhist guidance when it comes to how to deal with our aversions & judgements? I’m mostly sober now & plan to stay that way, but just because I’m on my own path, I feel that I shouldn’t judge others on theirs.
