[]]] California Pain Laws
California has two laws on the books dealing with the issue of treatment for chronic intractable pain. In the Health & Safety Code is the Pain Patient's Bill of Rights. In the Business & Professionals Code is the Intractable Pain Law.
If you know your state has such laws, or think it might, contact your public library to find out which branch has the complete set of state laws. I found that only the central library had all the books, complete with updates, while the branches had excerpts and summaries. Search through the available subject indexes (which may be available at branches as well as the central library) to find out if such a law or laws exist in your state.
1.) Division of Health & Safety Code Part 4.5 -- Pain Patient's Bill of Rights
2.) Business and Professions Code -- "Intractable Pain Law"
