As a doctor practicing for 30 years, I sometimes have patients who then move to other states and have a hard time finding Physicians there. I am a psychiatrist and there is a national shortage of psychiatrists. In fact we are allowed to prescribe in certain circumstances in other states and this has been life-saving for some of my patients. I am not talking about opiates, which I don't prescribe, I'm talking about virtually all other medications, some of which are controlled such as benzodiazepines which my patients with epilepsy often require long-term to stay seizure free. To "carry and administer" medicine, not so much, but to sanction our ability to prescribe across state lines, absolutely.
