Are there really people out their purchasing hardcore pills on the web instead of visiting a doctor?
TONS. I work in the rehab field on the AdWords side, and that's what we see over and over - people can't get them from their doctors anymore, so they get them online. I dunno how, because I thought it was illegal too, but they do.
But what about ads for other prescription drugs like Ambien CR?
Google already has a bunch of rules about this, both on the pharmacy and trademark level.
