The present invention provides compositions comprising therapeutic nucleic acids such as interfering RNA (e.g., dsRNA such as siRNA) that target aldehyde dehydrogenase (ALDH) gene expression, lipid particles comprising one or more (e.g., a cocktail) of the therapeutic nucleic acids, methods of making the lipid particles, and methods of delivering and/or administering the lipid particles (e.g., for treating alcoholism in humans).
