One sided relationship

My husband hangs around with my brother who constantly drinks alcohol every day smokes weed and is so brainwashed he’s like an evangelist for weed telling random people on the street to smoke weed. He deals weed. He talks loudly about dealing it. My husband who is a professing Christian but doesn’t go to church doesnt pray smokes cigarettes and swears. Now drinks all the time with my brother every time he sees him. I’ve spoken to my husband that I hate him drinking and it’s not good for my brother or for me having used to be an alcoholic myself I’m just so ticked off. I go to church alone and it’s just really tough. Advice please. It’s like he’s advocating and supporting my brothers addictions rather than being a light he has turned into a mess
