Body makes its own morphine

A study was done using mice, showing that they possess the ability to create the necessary chemical reactions within their bodies to create morphine. Scientist believe that all mammals possess this same ability, including humans. Many questions still remain about the process, as the ground is just breaking with these initial tests. Scientists hope to pinpoint that exact location within the body where the morphine is being produced. They also hope, with further research, to discover the "unknown" reason why the body makes it in the first place.
