Interesting chapter! Just don't overdo the gruesomeness!

Hmm...I like how you seem to know what you're talking about in this small chapter, I hope that you've done research or had first hand experience, either way, but to me I don't think I have to worry about it, since I was very convinced by this mystery drug's existence. I didn't quite like your allusions to Alice in Wonderland, because I consider them a little over-used in these types of situations, with drugs, ect. But I did like how you started the chapter off with the reference and ended with it-that was consistent, and even if the allusion was overused, it pulled the chapter together nicely.

It's really sad how people sometimes make the wrong choices which change their life. Maybe you can add a little authors note at the end adding some facts to make it clear that this changed the narrators life for the bad.
