What should an expatriate do who lives with friends who consume hashish, and he has tried to advise them without success, and they have begun to avoid him?

We advise you to look for another dwelling with righteous people who do not commit evil deeds. Until that becomes possible, avoid these people who wrong themselves, and refrain from sitting with them and condoning their wrongdoing. Continue to advise them that using hashish is among the most reprehensible of evils. Do not pay attention to their words, and abandon them if abandonment will reform them.
