I’ve seen the needle and the damage done
A little part of it in everyone
But every junkie’s like a setting sun

It’s usually the simple lyrics that get me.

I know people have said the “setting sun” line refers to an addict burning out which is great in its own right but I always also loved the secondary meaning of how it alludes to the way in which an addict constantly burns out and it’s a guarantee they will be right back the next day for more just like the sun rises everyday.
