Cannabis has been used as a medicine for thousands of years. A body of evidence suggests that this plant, which contains hundreds of active compounds, has potential value for certain patients undergoing cancer treatment. However, largely due to nonscientific political issues, marijuana is still classified as a schedule I drug—an illegal substance having a "high potential for abuse" and "no currently accepted medical use in the United States." This classification, which has been repeatedly challenged, greatly complicates scientific research of this plant's medical potential.
