Addiction meds linked to depression

Anti-addiction medications designed to help people quit smoking, lose weight, and halt their addictions to alcohol and illegal drugs have been linked to depression, new research suggests. These drugs work by blocking pleasure centers in the brain that provide the feel-good response from smoking or eating. But experts say these drugs may block pleasure too well, possibly raising the risk of depression and suicide. A reporter from CNN explores the risks associated with such medications as the anti-smoking pill Chantix and the obesity meds Acomplia and Taranbant. The reporter also talks to experts about how problems with these drugs may affect the future development of addiction meds.
