Lyric discussion by Tobycek 

Clearly the drugs interpretation is right, but I had a different idea for the chorus. I hear it as: "I used to think that the day would never come I'd see the light in the shade of the morning sun My MOURNING SON is the drug that brings me near To the childhood I lost replaced by fear"

I understand it as a guy who sees the reaction of his own son to the effect drugs are having on him, and this is the thing that shakes him out of it. It's the one thing that reconnects him to the time before drugs were in his life. In this sense, thinking that "the day would never come" means that he never thought this day would come, where he finally gives it up.

Weird, eh? :-)

@Tobycek I think you're looking too closely into things, finding meanings that are infact simply not present.

Well spotted! And while I do not think that was the intended use, I am pretty sure you can not look too closely at an art form which uses word in creative ways to say things the words themselves do not say.
