I’m going to agree, perhaps you’re fearful of the weed they’re smoking, you have never mentioned that they behave aggressively towards you or say threatening comments. In Canada weed is legal and I can honestly say that I’ve seen more people misbehaving when drinking alcohol than smoking weed. The only thing that I don’t like about it is when they smoke indoors and it comes into my home, now that is what I call invasive, thankfully I dropped a note in their door asking them to go outside on their balcony and thankfully they complied, good luck with your mission.
