Toads are frogs, but not all frogs are toads.
As a member of the MDA Care and Well Being committee I have run into dentists and team members who have chemical dependence issues. People involved in health care who are addicts often find themselves using opiate pain medications (Vicodin, Oxycontin, Lortab, etc.) due to easy access.
Most of the dentists who have a problem with opiate pain medication make a point of having it available in their office. With an account and a DEA# most any supply house (Schein, Darby, etc.) will send you pretty much any pill you might want. This is a drug addict's dream, and any addicted dentist can get away with it.
There are Michigan dentists who keep controlled substances in the office (frogs). Some of them have them in the office for good reasons, but some keep them around so they have access to them for the wrong reasons, like personal use (toads).
There could be a good reason to keep controlled substances in the office, but it's easy to allow a pharmacy to deal with the headache of keeping track of them. To dispense medications from your office you need a drug control license, a lock box, a procedure for keeping track and you need to dispense them in properly labelled and child-proof containers. If you dispense controlled substances, you need to do all this and electronically submit your dispensing information to MAPS twice per month. Why go through the hassle? I can maybe see dispensing Chlorhexidine and Prevident from the office, but not much else.
The moral of my story: don't be a toad!
