One World Essay: Chemical Abuse

For the first time in science we are writing a "One World Essay". That means that we had to chose an issue, that has something to do with chemistry or chemical reactions, that we have seen and write an essay about it. The topic I chose to do is chemical abuse. Below are some great sites, I've looked at to get an idea of what I am studying. There is also a link to my bubbl.us account so you can see my brainstorm! Hope you enjoy it!
