Sounds like an improvement, depending on how you look at it. Having experience with these types pharmacies going back decades, most used to just fill fake schedule II bottles with placebos, or worse, random Schedule III pills.
If you’re already copping, or trying to, illegal prescription narcotics in Mexico, you probably already know what you’re in for. You want to get high and you don’t have a doctor’s prescription.
Not saying this is good, just that it’s probably not surprising or unexpected to the people most impacted by it.
