It's something we should be able to openly talk about as substance abuse is an illness. You can also make memes about an illness as a means of coping with it or to commiserate over it with others.
I don't think this is normalizing it at all. There's more of a self-deprecating subtext, and it's not too dissimilar to the humor I hear from other addicts/alcoholics (been sober from alcohol since 2017 myself)
