I don't know why an optician, licensed or not, would be supplying Rx's for Canada. That must have been a typo. As for pharmacists, I can only say that for me being able to buy drugs from Canada has been beneficial. Fortunately, I do not need any meds but my wife is a cancer patient and does. I can get the same legend drugs from Canada that I get in this country at a savings of 50-70%. And the Canadian pharmacies will not ship without a valid Rx from a U.S. physician. Some of these drugs, by the way, are made in Canada.
The pharmaceutical companies spend millions of dollars on TV commercials and print media ads trying to convince people to use drugs that only a physician can prescribe, thereby encouraging patients to tell their doctors how to practice! They should stop that stupid advertising and reduce the cost of their meds.
