My uncle is drug addict and always invites his druggie friends to do drugs inside our house?

I live with our uncle. Actually my mom my sister and my family lives in a one house with him and he doesn't have his own house so he lives with us and he has his private room but he always invites his druggie friends every midnight to do drugs and I just dont trust them when Im sleeping in the couch. ( I dont have my own bedroom) I just dont trust drug addicts and I don't know what to do? he's been in and out of prison and seems like he doesn't want to change. He lies t get money, steal our stuff to sell to people to get money, and he's also a peeping tom. Unfortunately rehab is very expensive in our country its about $1,000 a month When he is not using drugs he is gambling all day. I dont feel safe at home with him. how can I stop stressing over this?
