In Canada we have usual ads for OTC drugs and vaccines, but for prescriptions it's weird.

You're allowed to advertise that a drug exists for Condition X, but can't say what that drug is, OR that there is a drug out there called Drug Y, but can't say what it does or what it's for, and you're not allowed to combine the two. So we get the most inane ads out there where every single one is just a bunch of stock photo looking people doing stock photo things, talking about how they asked their doctor about drug Y.
