I think you have not just the right but the obligation to set boundaries of what you will and will not allow in your life. Failure to do so results in all sorts of escalating problems. And yes, there was a meth bust one block north of me, one block west of me last week. I live in a meth-riddled area as does much of rural America. A person has the right of association..they have the freedom of speech, you have the right to shut them out of your life. mg
