I think the disagreement in this thread stems from the following:
Many people think they have a "RIGHT" to receive/purchase medication. No where are you guaranteed the right to medication. We just happen to live in a country where there are pharmacies offering to sell you the medicine. So by not filling a prescription a pharmacist is not stifling your rights as you have none to receive the medication. He is stifling you convenience by not filling the script and forcing you to go somewhere else.
Keeping the script unless the pharmacist believed it was forged or counterfit was defintely wrong and he should be punished accordingly.
Will pharmacies who employ pharmacist who make these decisions probably lose business, etc.. They probably will, but it is within there rights to do so.
