I am currently taking the ASAM 24 hour waiver training required for buprenorphine and it has some really great information for opiates and opioids. Even if you are not involved in addiction medicine this is a great resource of what to look for and how opiate addiction is being treated. Plus, AANP has approved a portion of it for the required pharmacology hours for recertification! Please consider taking the course.  Sign up takes a couple minutes but the course is free.
