KARG: Knowledgebase for Addiction Related Genes

I was perusing the new PLoS Computational Biology just now, with my hands gripped to my coffee mug. I spotted this article:
Genes and (Common) Pathways Underlying Drug Addiction by Li et al. I was wondering if the genes that direct me to coffee each morning were identified. But it doesn’t look like they covered coffee. The list of Addiction Related Drugs from their site has other plants. Alas.
