Remains: A dying Siberian maiden who lived 2,500 years ago may have self-medicated with marijuana. Russian scientists using MRI scans determined that the #mummified and tattooed body of the "Ice Princess" showed breast cancer. In addition, scans found evidence of injuries consistent with a fall ---perhaps from a horse. To cope with the pain she must have been experiencing, the princess could have resorted to cannibis---which was found alongside the #mummy in her burial chamber.
