In lieu of a law change, treat drug ads like drugs themselves
In the rest of the developed world (again, except for New Zealand... weird, right?), drug ads are illegal. As long as there have been medicines marketed in America, their benefits have been exaggerated, or outright invented -- we're a proud nation of salespeople, but that doesn't mean everyone should be a gullible consumer.
Drug companies will say whatever they can get away with to sell their stuff, just as they always have. As long as we allow them to do so, we’re the ones lining their pockets... and if you choose to buy into the pharma industry's logic that drug ads educate and empower consumers, consider this the necessary list of side effects.
