Hello- I am in need of some help as I'm not sure where to start but I know something is wrong. My brother lives with me in my basement and has been showing some serious signs of addiction. I know that he smokes weed and has for years, however, the things I am seeing are not anything I have ever known to be associated with marijuana. I have come downstairs to find him nodding out sitting at his computer. I yelled in the room to him and he looked right at me but it was like he didn't see me at all.....Last night I came downstairs to get laundry and he was leaning on the hallway wall. When I tried to get his attention, it was very hard and had to shake him, he then shuffled off to his room and shut the door. It's crazy because at other times he comes upstairs, very loud and excitable for no apparent reason. I am very worried as I have young kids and am concerned about explaining the behavior to them and also worried about my brother's health....Please help!
