No weed in my house

I am very conservative when it comes to cigarettes and other types of smoke. My husband is having his friend come for the weekend and he warned me that this guy smokes weed and I said there is no smoking allowed in my house. He said his friend will smoke outside and I still don’t like that at all. I know I’m being annoying but I really don’t feel like dealing with any problems. My husband is against smoking and never has but can’t put his foot down when his friends do something. It’s pissing me off that he has no boundaries and thinks everything is okay. I honestly don’t even like the idea of a friend sleeping over in my house but I’m chilling out about it. Getting really sick of his behavior and being able to please everyone but me. I may be too anal but that’s just how I am. Is it wrong to be upset about this?

Update: the friend is a giant pot head and wants to smoke in the backyard with a bunch of nosy neighbors. We are new here and don’t know what kind of people we are dealing with and if they are crazy and call the cops. Also, it is not medicated marijuana and it is extremely illegal in our state. Mind you, since we live on a hilly neighborhood most people can see what we are doing in the backyard. If the friend was going to walk outside and do his business then I don’t care. I just don’t like having things done on my property and where I live. Not controlling, just very alert 🚨

✨ update number 2 ✨ some of you need to chillllll lol. I told him the friend can do whatever he wants outside (even though I disagree) and the conversation lasted 10 seconds. I just said not inside. I said “my house” a couple times. Maybe the wording was off big deal! I just came here to rant. Didnt know I’d get so much hate 😂

✨ update 3✨some of you have wayyyy tooo much time on your hands to be writing these newspapers of assumptions. Keep them coming it’s so entertaining 😂
