I feel the song is about deep love or relationship and how you behave and feel when you are completely consumed by it.
Same way a drug consumes you.
Its sometimes messy ,but you are so consumed by it even knowing you are free ,you have choice to get out of it, you can quit, you don't quit because you are in love with the addiction and like being sedated by it.
"Our veins are busy but my heart's in atrophy" : how restless you feel inside even though you are busy in some thing.

"You and I nursing on a poison that never stung"
