"You're remarkable astute, for that is exactly what they do. No matter its intention or effects on humans, any drug I ingest merely dulls out the 'second sight' that makes me what I am, and counteracts the 'high' I get from utilizing it. Without those same drugs, even that relatively short trip we just took would have left me dazed and dreamy for hours. With them, it was about twenty minutes, a bit less. I could have taken more to cut the time down sooner, and have when necessary, but it's dangerous to do so. Navigators are not Space Marines, we do not process toxins instantly but only ignore them. I'm sure that if I took enough, it would kill me just as dead as a normal person, but I would feel none of its influence in the meanwhile."<br/><br/>He drained the last of his amasec, sliding the cup to one side for now. "Alcohol, on the other hand, is one of the few precious ways in which I am completely, absolutely human to the last drop, so to speak."
