The fine print will say "this drug has not been tested and is not approved by the FDA. It may cause death or create an uncontrolled viral outbreak..."
The drug will sell like hotcakes though because the commercials will have lots of happy-smiley people and the distributor will get a healthy 80% profit margin on the sales.
There's some comfort in knowing that a non-profit agency is looking into the safety of a drug before it goes out to the public for consumption.
