Cover art for Weapon lyrics by Matthew Good Band

I think there are many ways to interpret this song but my personal feeling is that it's about drinking and driving. It is a weapon. "Breathe in, breathe out" after being pulled over. "Give in" to the temptation, and then your mind "give(s) out". "Heaven" is how you feel but it may lead to "destruction". You could also interpret as a political song or even about a relationship. It's pretty obscure.
