Summary
This study is being done to see whether Avmacol®, a dietary supplement made from broccoli
sprout and seed extract powder, induces changes in inner cheek cells that may be protective
against environmental toxins such as tobacco.
There are three main goals of the study:
1. To learn whether the dietary supplement, Avmacol®, can stimulate cheek cells to repair
damage from environmental toxins;
2. to learn how the body metabolizes Avmacol®, by measuring its byproducts in the
participant's urine and blood;
3. to learn whether the immune system can be stimulated by Avmacol®, by studying the
natural killer cells and T cells in the participant's blood.
