I've been a drug addict most of my life, spent most of my time around opiates until I cleaned up, but met PLENTY of tweakers. Not until someone mentioned did the thought cross my mind, but the way he talks, as well as acts, its so similar to tweakers. The grandoise thoughts, as well as the speech patterns, and the jumping from topic to topic. It could be a strategy to avoid answering questions, but it seems eerily similar to friends I have known and lost. I really want someone to challenge him to a drug test.
