It sounds like your brother has created a great place to be while he considers his next move. Working with the animals most likely is very satisfying also. I guess being out of a body must make it different to do the pot thing. Can't hurt himself by smoking. No lungs to hurt or stuff like that. No fingers to burn with the roach. Perhaps he eats it? I find it interesting that he would even want to do it. If you get the chance, ask him what the purpose of the pot is there. Like you said, it might br just to annoy you.

hi Vee, have a suggestion: the next time you see your brother suggest to him whatever he "feels" when imbibing the pot, that he can bring that feeling into himself without the actual substance. with practice he will maintain the experience of being high at all times with his mind control.

the more I think on this retrieval I'm reminded when I visited with my deceased exhusband awhile back. it was a sleep retrieval I am thinking now.

Mike was an alchoholic. I learned later his pancreas was totally dead organ while he still yet walked around in his body. didn't know that could happen. gives new meaning to the phrase "walking dead man." 
so in the retrieval I was just appearing in his living room as my intention was to be checking out his welfare on the other side, his spiritual progress.
no one was in the room at first so I waited and he walked in looked at me, sat down some small object. now I think it was a glass. he liked bourban in a glass. but I blocked it out what he sat down, as I wanted to believe, that he was over the addiction. now I think I just didn't want to see that glass.

so anyhoo, part of my intention I remember now, for going to see him was to inquire about the addiction, so I must have had this thought in my mind and he sat the glass down due to 1) out of respect for me or: 2) he really had sat liquor down, to be done with it.

the reason I'm thinking I did  a retrieval rather than a visit, is two guides showed up in his kitchen and began talking to him about his future. I got the feeling the guides had been to see him more than once, that they were working on him friendly like. he was slow to warm up to new ideas. maybe stubborn is the word.

so if they were there before me, then maybe it wasn't a bonafide retrieval, I just know retrievals always have guides handy somewhere in the picture. well, in the beginning phases the guides are there. its not always they reveal themselves though.
I'd like to think I had something to do with the help he was getting, to advance along, he was such a non social type guy, and the guides were trying to get him out of himself into social and team work type environments, so it was all good.
