I quit smoking, but my partner won’t

My husband and I used to party hard together, until I got pregnant. I still smoked while pregnant and he cut down on drinking, having no one to go with. And now my boy is 8mo and I hate being high around him it makes me feel like a terrible mother… *instilled in me from my parents* but my husband likes to smoke still. He is so much happier, and more attentive as a father when he is high, but it makes me so angry to see him high. Like parents aren’t supposed to need drugs to appreciate life. I’m just so torn by my emotions. I keep trying to override my morals and justify weed is as much a medicine as pharmaceuticals, because my husband is better high, it’s just the blazed eyes that break my heart.
