Pharmacists pick up on the subtle but then there's the obvious. If you're going to pass a fake Rx, your FIRST step is DON'T WEAR DARK SUN GLASSES. You'd think they'd figure it out by now. But no, they haven't. Week after week, WEEKEND after WEEKEND, here they come marching in with the fake prescriptions... Oxycodone 30mg #120, nearly perfect handwriting, filled out with date of birth and even address. Yeah, all my busy doctors do that, sure.
But the first dead giveaway is the dark sunglasses. It immediately says you're hiding something. And apparently there are still a few pharmacists out there who never question any of it, and maybe that's why you do it.
But don't expect to come around my pharmacy wearing dark sunglasses. I'm going to immediately check your Rx top to bottom, inside and out, to figure out if it's a fake.
