kate mcmahon works for the medicines regulator. we're about to put maggie's hunch to the test.w what you are going to find. that's part of the excitement. you think, what am i going to see? what am i going to come across? it's always handy to have a sharp knife. absolutely. what have we got there? clearly labelled, diazepam tablets, 10mg. the 10mg version is the strongest you can get. for us, this is a good find. but it's also prescription only medication. this particular product, we'd say this is substandard unlicensed, so it's not licensed for the uk market. essentially, it's an illegal product entering the uk. in terms of quantity, it's certainly not for personal use. it's highly likely to be sold on websites, social media platforms. it might have diazepam on the label, but in reality you don't really know what the product is. while kate and i have been unpacking one illegal shipment, her colleague, charlie, is dealing with another. these claim to be a treatment for erectile dysfunction, but who knows? that's the danger of buying drugs illegally. border force has its own ons
