There's a lot of curveballs with Buprenorphine that isn't taught in the required training to get the license for the X-DEA number. E.g. they don't inform you that the withdrawal can go on for weeks, that even if you reduced the dosage to less than 1 mg a day the person can still have bad withdrawal when they stop it, that the studies on how long a person should be on Buprenorphine don't usually go past 1 year so it's not set in stone exactly how long someone should be on it, and what alternatives could be done on patients who are non-compliant with rules other than simply just terminating their treatment.
Another issue I see are several doctors are prescribing Buprenorphine but not providing therapy. They just have the patients show up, take their money, then give them a UDS (if even that) and the medication and bye bye. This is minimal and poor care. Some doctors here even defended the practice completely ignoring that there's a doctor-patient responsibility to this patient and not even screening the person for other disorders such as ADHD or depression.
The above curveballs aren't as mentioned above rocket-science but if you start doing Buprenorphine, don't expect the training for the license to cover these needed areas.
