Ecstasy and anti-depressant drugs such as Prozac have the potential to stop cancer cell growth, research has found. A University of Birmingham team tested the impact of amphetamine derivatives such as Ecstasy and weight-loss pills, and antidepressants including Prozac. They found the drugs were effective at blocking cancer growth in more than half of lymphoma (white blood cell cancer) samples tested. It is hoped the FASEBJ Journal study will will lead to new cancer therapies.
