For my nephew DJM who has been struggling with a multi layer drug addiction. He refuses to acknowledge this problem and believes any form of drugs is good for him and helps him. Of late we have noticed that his mind has become very dull and is not capable of holding onto any job more than two years. He sees the the world as a place that is out to get him, holds to himself very rigidly. Has built walls around himself, and allows very few to penetrate.
