Bryson's primary prescriptions were for hydro. This is not the 1st or last time I have heard of the DEA warning people. People please remember the DEA has the hard core agents then a whole separately funded division called diversion and we may trivialize their responsibilities but visits like these are part of their job. Many members have pm'ed me over the last 18 months most of them just receive warnings. A few have faced charges that were reduced however who wants the hassle? The odds of getting popped? Slim but it does happen and it's usually not some grand scheme that causes the investigation just bad luck.
Take care. Billylll
