Summary

This study tests whether a broccoli seed and sprout extract can help heavy smokers break down and remove cancer-causing chemicals from tobacco. About 135 current smokers will take either the extract or a placebo daily for several weeks. Researchers will measure changes in urine levels of toxins like benzene and acrolein to see if the extract boosts the body's natural detox process.
