"In terms of my lungs, pot smoking is not like cigarette smoking. It doesn't affect the lungs as quickly, or as much over time. If I stopped pot smoking today, my lungs could heal probably 100 percent in a few years."

For the first thirty years of my life I exercised very little, and I smoked cigarettes for ten or twelve years, and I ate junk food. And I began to see some elders in my community's health decline, and I didn't want that to happen to me.
