Lol, yeah, that started reason doesn’t hold up well. Your basic urine drug screen (UDS) will flag benzos (midazolam in this article), natural opiates (not fentanyl and those derivatives), cocaine, barbiturates, marijuana, amphetamines, and I think that’s it. The only ones likely to cause fetal withdrawal are benzos and opiates. Works well enough for benzos, but withdrawals are pretty rare. The most common are opiates, but the most common opiates won’t show up on the UDS. So why use it?

The latter is called “doctor shopping” and it absolutely happens.

The goal of the advertisement is to have the patient be interested, not the doctor. Admittedly some doctors are not up to date on the latest obscure cutting edge treatments, so there is some possible benefit. However, most doctors are capable of performing cost benefit analyses and understanding side effects, but when a patient comes in asking for a medication, it definitely tips the scales towards the medication.
