@Cowy- simply antagonizing the original poster looking for honest input isn't very sporting. If you want skew off topic to discuss the merits or uselessness of incorporating CAM/Integrative medicine into FM Residency curriculum you should start a new thread.
You can start by taking issue with this pdf article by the STFM group looking at CAM in Residency training:

For the original poster: You'd probably be the most interested in the Santa Rosa, CA program which is not from what I can tell connected to the Arizona group (see below). The above article mentions the 8 programs affiliated with the Arizona group mostly through online web modules. Each program is at a varying level of individual development based off of particular faculty interests. The Beth Israel NYC program has a month incorporated and also actually has acupuncturists on staff in the hospital that will do inpatient consults and sessions. As far as resident involvement I am not aware of much (but fellows could be a different story).
My impression of the Arizona program and affiliates is that they prepare you more to work with other CAM practitioners within the community rather than really allowing you fully explore your own development in a particular modality. I think this is fairly justified as Family Medicine (the broadest field) already has an incredibly difficult job in cramming in all you need to know in 3 years. This being said most programs have between 3-6 months of elective and most program directors I've met seemed like they would be more than willing to let you do a month away in further training in something like acupuncture.
As far as longitudinally doing acupuncture in your outpt clinics the way some programs have setup for Osteopathic Manipulation for DOs-- it would be difficult but not necessarily impossible. You could speak to a program director about it but from his/her point of view there would probably be concern about how much it might take away from your regular clinic duties and ability to fulfill those requirements/responsibilities. In addition there might be some discomfort of having sufficient oversight if there are no faculty that would be involved. It might look something like taking one half-day a month (especially in R2-R3 years, probably not R1 year) to refer all your patients to for acupuncture, perhaps other residents might refer pain/headache pts to you as well (obviously 1x/month not ideal for patients requiring regular sessions).
As far as other programs that already have something started in addition to the Arizona 8 there is also Lawrence, MA and Santa Rosa, CA. Both of those are interesting in that they focus specifically on integrative medicine for underserved populations. I did not see much in the way of R1-R3 involvement at Lawrence for Integrative medicine- seemed more like a fellowship thing, and I am also unsure of the presence of TCM/acupuncture.
Santa Rosa has at least 3 faculty that use supplements as they precept in regular outpt clinic. An herb company in sebastopol (the neighboring town) also donates products that they can distribute to patients. Some previous residents have gotten trained in acupuncture during residency, but the meat of what they do from an integrative point of view is that they have an clinically based integrative medicine fellowship. So after the 3 years you can do an additional year that is focused on you developing a specific modality you want to or already have started to develop (ie you could definitely use your acupuncture in clinic). Their main integrative faculty have specific interest in TCM and Ayurveda I believe. As far as using herb products from Chinese formulas that they themselves are unfamiliar with-- they would still probably want some sort of evidence to back up your use of it before they would sign-off on it.
As mentioned above, PM&R is also another great field with implications for acupuncture although I believe they tend to use it there mostly just for pain indications.
Hope this was helpful. PM me if you have any additional questions.
