They have a place in such things as antibiotics, where there's a public health problem (MRSA, anyone?) if used indiscriminately. A debatable claim can be made for marijuana having a public-health risk that justifies regulation.
But the key is "regulate," at an appropriate level. Banning use by patients who could benefit from it, with minimal public-health risk, is a different story.
Spot-on! I've thought of this a lot. There was a time that I wished I could purchase 2 tablets of a helpful drug during needed times. But the prescription was costly after considering the doctor visits. I wondered if registering as a user with one specific pharmacy and then having a purchase limit would help.
Of course, there would be druggies abusing this system....as with anything. But it would lower the government's intrusion into honest person's lives. Again, we have the criminals forcing the honest persons into government systems.
Strangely, the lawmakers show us they have more human failings than us....and that's putting it lightly!
