Jay Maynard writes:

If a doctor orders it. It's not difficult to obtain such an order, but
without it, they can't do it legally. The law says that the medication may
not be dispensed without the order of a physician. Dispensed does not mean
"used or administered", it means "sold or delivered by a pharmacy or drug
distributor or manufacturer".

Not true. Drug manufacturers deliver drugs all the time to pharmacies and
they do this without prescriptions.
