Saw this story on bbc.com about Rimonabant -- a controversial weight-loss drug that was approved by the Britain's NHS. The drug has apparently been linked to an increased risk of depression and suicide especially among those already taking anti-depressants.

The story got me thinking about whether drugs that have death or suicide as a side effect should be approved? If so, does the patient and doctor assume all risks associated with the drug? Should a drug not be approved to protect a few with high risk factors?
