Interesting article, just one thing though, how exactly can someone 2pharmacy shop"? In the UK you get a prescription, hand it in and that's it, one prescription one pharmacy, i can't see how people can use the same prescription at more than one pharmacy.
SWIM has heard of this being used with online pharmacies. Scan the script, email it to a legit online pharmacy, they confirm the script and send it. Then take the paper script to a local pharmacy, which won't confirm it. This is highly illegal, and not recommended.
