Drugs and Toxins

I am thinking maybe I need to include more examples of Drugs and Toxins in the next version of Errant. I know some might call a template of how they work with a single example sufficient. But I am thinking a short appendix might be useful. The only drawback I see is that doing so might stifle creativity a little as people fall back to the same old stuff every game: "Potion of Cure Light Wounds" and whatnot. I want to encourage innovation on the GM's part.

Thoughts?
