From publisher blurb: This six-page PDF, Modern Chemistry uses the rules provided in the Little Black Drug Book to present a variety of fictional drugs for use in a d20 Modern campaign. By no means does this product seek to trivialize or make light of the seriousness of drug addiction. But, most GMs should find Modern Chemistry useful for introducing both the positive and negative game effects drugs can have on Modern heroes and supporting characters alike. This product is an excellent supplement to the Little Black Drug Book.
