What are the chances that everyone here is right? I mean, is it possible that the message is something along the lines of "I've ruined my brain and not only may I trade you for yours, but could I also rely on you in the future, given how you've helped me now?" Maybe it's a stretch or maybe I'm being too objective, but I think it can have both meanings. Even if much of the phrasing ("blasting holes", "seeking stars") suggests drug use, the idea of supporting someone does fit.
