Hellobee Boards

The article doesn't link to the FDA.

To be honest I don't fully trust the FDA, I think they are easily persuaded by big companies to refrain from admitting to things until they absolutely have to. They allow drugs on the market that haven't been fully tested only to ban them later when there are horrible side effects later.
