I am curious to how you and Stacy do this together. Do you alternate verses or do you actually do it together, helping each other with each verse. At any rate, I like this shared masterpiece!

Word Usage:
You painted a clear messsage of what addiction is all about. what the user feels, what the consequences are of drug usage. The reference to the drug being a 'her' makes it quite (hmm, what is the word I am searching for?) spooky? Personal?

Structure:
There is a definite rhyme scheme that changes through out the poem. Some verses seem to follow a 'ababab' scheme while others seem to have each line rhyming with each other. Very nice. The flow was great!

Imagery:
*shudders* I found this a frightenly true picture of addicition.

A drug induced dependency amidst this darken hole –
craving a chemical convention, ever out of control.
A tearful, terrifying rendition finally taking its toll –
a seductive senseless satire; stealing this tired soul.
The last verse could say it all but anchors this entire piece beautifully.

Emotions/Feelings:
Being that i have 'been there, done that', I can relate. I do, however, think this paints a clear enough picture that even a person who has never touched an illicit drug in their life could clearly see what 'using' causes users to become.

Overall Impression:
I think you and Stacy are an excellent team! this was indeed a masterpiece
