Working on a novel about drug culture - would greatly appreciate feedback

[washingtonbound]

Hi all, I have been toying with the idea of writing something centered around young people using drugs ever since I read "Less Than Zero" a few years ago. It is geared towards the 18-25 age demographic but hopefully older people would enjoy it as well. Here is the link: http://www.writerscafe.org/writing/CATVLYST/1959924/
I would greatly appreciate feedback; if you have a piece of work you would like input on let me know and I'll share my opinion as well.
Thanks.
