Based on her personal experiences, Mara Gordon, co-founder of Aunt Zelda's, has become passionate about using cannabis to treat patients with illnesses and injuries. Gordon notes that, based on her data, THC is the most medically useful cannabinoid, although she is also a strong proponent of medical-use CBD. She also points out that, typically, younger patients require higher doses, whereas older patients require lower doses. This could be due to number of cannabinoid receptors, metabolism speed, or mere differences in psychology. Besides science, Gordon believes that products need to be well understood with everything printed on the label.
