I believe this song is about freeing yourself from anything holding you. Whether drugs are involved or not, we all sometimes have feelings that imprison us, that repress or arbitrarily invade us making us feel bad. Hence the chorus about not getting enough space in a way that leaves us overwhelmed, indecisive, frozen in panic in front of conflict. Screaming for space is a way to demonstrate that we also think and feel. It's the end of the dead end road.
