It's a question of professional responsibility. Only a qualified health professional can prescribe in medications. Because he knows the human physiology and the chemistry of the drugs he prescribes.
Unfortunately, training, diplomas, skills and permissions are very different in eatch countries of the world.
I think our Asgardian health ministry needs to think about this.
As a psychologist graduated in France I can offer psychotherapy but I can not prescribe drugs because I do not have the necessary training in physiology and chemistry. Being citizens of Asgardia don't give me these necessary knowledge anymore. So I will not prescribe drugs and let the physician doctor do.
We need to bring together all Asgardian's graduated health professionals. Then we can think together about our own health system: powerfull, fair and for all.
