Just as passionately she believes that education about cannabis along with safe, quality, and tested products will help to remove the negative stigma that continues to prevent cannabis from becoming mainstream medicine. This will change when regulations are in place that will set standards for growing, testing, producing, and packaging cannabis as a medicine.
