Lots of places do RC synthesis but almost all of them get their precursor chemicals from China, with India a distant second. China also does a huge amount of bulk research chemical synthesis. A lot of Benzos and Ketamine come from India, and India has been the number one supplier of bulk ketamine for ages although China has started to do clandestine ketamine synthesis more recently. Pharmacy robberies account for a small percentage of pills on the market I imagine, a lot of them are high quality counterfeits pressed with bulk powder clandestinely synthesized in India usually, and a lot of them are from pill mill operations where doctors write scripts to accomplices (Florida is a hot spot for this). You would be surprised how many pills on the illicit market were pressed in some garage by some dude with bulk powder connects.
